Full textAbstract:
Micronutrient deficiencies are a major problem throughout the world and hundreds of millions of the world's population are affected by micronutrient deficiency disorders. In Europe the prevalence of clinical micronutrient deficiency disorders is less than that in the Third World. However, marginal deficiency of some of the micronutrients might be involved in the aetiology of many of the so-called lifestyle diseases, e.g. cancer, cardiovascular diseases, diabetes, osteoporosis. Supplementing domestic animals with micronutrients in excess of their needs could be one strategy to increase the intake and, thereby, status of micronutrients in the human population. This approach should, however, be considered carefully, in relation to both animal and human welfare. Many micronutrients that may accumulate in animal foods are toxic in high doses. It would also be unethical to expose animals to doses that might have deleterious effects on their health, and concentrations in animal products that might have adverse effects when consumed by man should be avoided. Furthermore, food quality should not be impaired by the supplement. On the other hand, to be relevant in relation to human nutrition, the given micronutrient should accumulate in animal tissue in concentrations that make an important contribution to total intake. Finally, the micronutrient should be incorporated in a way and in a form that is bioavailable to man, i.e. is well absorbed and utilized.

Full textAbstract:
Earlier, after our bioinformatic analysis of single-nucleotide polymorphisms of TATA-binding protein-binding sites within gene promoters on the human Y chromosome, we suggested that human reproductive potential diminishes during self-domestication. Here, we implemented bioinformatics models of human diseases using animal in vivo genome-wide RNA-Seq data to compare the effect of co-directed changes in the expression of orthologous genes on human reproductive potential and during the divergence of domestic and wild animals from their nearest common ancestor (NCA). For example, serotonin receptor 3A (HTR3A) deficiency contributes to sudden death in pregnancy, consistently with Htr3a underexpression in guinea pigs (Cavia porcellus) during their divergence from their NCA with cavy (C. aperea). Overall, 25 and three differentially expressed genes (hereinafter, DEGs) in domestic animals versus 11 and 17 DEGs in wild animals show the direction consistent with human orthologous gene-markers of reduced and increased reproductive potential. This indicates a reliable association between DEGs in domestic animals and human orthologous genes reducing reproductive potential (Pearson’s χ2 test p < 0.001, Fisher’s exact test p < 0.05, binomial distribution p < 0.0001), whereas DEGs in wild animals uniformly match human orthologous genes decreasing and increasing human reproductive potential (p > 0.1; binomial distribution), thus enforcing the norm (wild type).

Journal of the American Veterinary Medical Association 202, no. 6 (March 15, 1993): 865–72. http://dx.doi.org/10.2460/javma.1993.202.06.865.
Full textAbstract:
Summary: Surveys were performed in which the state veterinarian and the major state veterinary diagnostic laboratories in every state were asked about selenium (Se) deficiency and toxicosis in livestock and wildlife in their state. Selenium-deficiency diseases were diagnosed in 46 states and were reported to be an important livestock problem in regions of 37 states; deficiencies were diagnosed in wildlife in 10 states. Natural Se toxicosis was a rare problem, with only 7 states reporting naturally developing Se toxicosis. Oversupplementation with Se was reported as a cause of toxicosis in 15 states. Toxicoses in aquatic environments were reported from 4 states; in all cases, high-Se content in the water had resulted from agricultural irrigation or natural rainfall causing leaching of Se from high-Se soils. Current amounts of supplemental Se that can be fed to our major food-producing animals are being reviewed by the FDA because of speculation of potential environmental problems caused by Se supplementation in animals. Amounts of supplemental Se allowed in the western United States (states west of and including North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, and Texas) are proposed by the FDA to have more potential for environmental Se enrichment and toxicosis. This premise was not supported by our data. Selenium supplementation in domestic livestock was not involved in wildlife toxicosis found by these surveys.

Full textAbstract:
African swine fever virus (ASFV) is the etiological agent of an often lethal disease of domestic pigs, African swine fever (ASF). The ASFV Georgia 2007 isolate (ASFV-G) is responsible for the current epidemic situation in Europe and Asia. Genetically modified ASFVs containing deletions of virulence-associated genes have produced attenuated phenotypes and induced protective immunity in swine. Here we describe the differential behavior of two viral genes, NL (DP71L) and UK (DP96R), both originally described as being involved in virus virulence. Deletion of either of these genes efficiently attenuated ASFV strain E70. We demonstrated that deletion of the UK gene from the ASFV-G genome did not decrease virulence when compared to the parental virus. Conversely, deletion of the NL gene produced a heterogeneous response, with early death in one of the animals and transient fever in the other animals. With this knowledge, we attempted to increase the safety profile of the previously reported experimental vaccine ASFV-GΔ9GL/ΔUK by deleting the NL gene. A triple gene-deletion virus was produced, ASFV-GΔ9GL/ΔNL/ΔUK. Although ASFV-GΔ9GL/ΔNL/ΔUK replicated in primary cell cultures of swine macrophages, it demonstrated a severe replication deficiency in pigs, failing to induce protection against challenge with parental ASFV-G.

Increasing number of patients, who suffers from diseases such as immunodeficiency, autoimmune and inflammatory diseases, various congenital blood clotting disorders stimulate an increase in the pharmaceutical market in the number of drugs for treating these diseases. Providing high-quality, effective and safe drugs, obtained from blood is an urgent issue that can save lives.
The purpose of the work was to study the range of biological drugs containing active substances obtained from human and animal blood plasma and analyze the segment of these drugs on the pharmaceutical market of Ukraine for 2020. To study this segment, was used data from the State Register of Medicinal Products of Ukraine, the information retrieval program «Morion» and the ATX classification system of the electronic resource Compendium.online. Research methods: structural, statistical, graphic, generalization and systematization.
Established, that the segment of biologic drugs, derived from human and animal blood plasma, at the Ukrainian pharmaceutical market, are represented by 100 trade names of drugs, where 23% of the studied market segment is occupied by domestic manufacturers. The leaders of importing countries are Austria (31%) and Sweden (13%). Analysis of the nomenclature found, that the most common drug dosage form are lyophilized powders for injection and infusion solution (52%) and solutions for injection and infusion (35%).
Studies have shown, that the active ingredient in the largest share of blood products is the coagulation factor of human blood VIII (36% of the total assortment). The range of drugs produced using plasma of animal origin is limited, makes up only 14% and is represented by preparations of immunoglobulins (horse, rabbit) and drugs containing deproteinization of dialysate from calf blood. The lack of domestic technologies for obtaining PDMPs from cattle plasma (RED) with a sufficient number of cattle was determined.
Obtained data show, that blood is a strategic raw material for the production of a wide range of drugs for the treatment of diseases of various etiologies, interruptions in the blood supply can lead to regional and global deficiency of the main PDMPs, therefore, the development of drugs based on blood is relevant and promising.

Full textAbstract:
Evaluation of livestock genomes to identify gene complexes which lead to expression of the quantitative trait desired for breeding is impossible without knowledge of its fine molecular structure and characteristics of "work" of this complex system – the interaction of genes at the level of their protein products, regulation of gene activity, and so on. To address such complex issues focused efforts of leading scientists in the world who have worked within the mapping and sequencing the genomes of the most economically important species of farm animals – "transcript" of the genome of some dog breeds was completed in 2003, the structure of the genome of cattle, pigs, rabbits, horses and turkeys was identified only in 2009, and the noticeabout completion of international program "Honeybee Genome" appeared only in 2010.
The rapid genesis of methods of molecular genetic analysis of farm animals’ genomes is not in vain called "DNA Revolution" and the number of methodological approaches and developments in this field is huge, so we consider it appropriate to be limited to developments of a leading scientific center of Ukraine to address these important issues – Institute of Animal Breeding and Genetics nd. a. M.V.Zubets of NAAS of Ukraine.
The main focus of the institute is developments of scientists which help to solve an important problem of the state –preservation of the existing gene pool of domestic breeds. In this sense, the developments of genetic testing of cattle on the "major" genes of quantitative traits, involved in forming the qualitative indicators of milk and meat productivity (k-Cn, βLG, GH, TG5, CAPN1 530, MSTN), have shown uniqueness of domestic breeds and high frequency of genotypes desired for breeding aimed at improving quality of milk and meat products. For example, k-Cn (kappa-casein) gene can be determined in a herd of animals with genotypes determining the presence of milk protein with desirable properties for cheese-making and selection of animals on some genotypes of βLG, GH, TG5 not only helps to intensify breeding towards milk yield increase, but will increase its fat content. Some mutation, identified in CAPN1 530 (calpain) gene, will provide for its carrier –a representative of beef cattle breeds by expressed marbling of muscle and individuals with abnormalities in MSTN (myostatin) gene will have "double" hypertrophied muscle structure. By the way, convenience to address practical issues of production of molecular genetic markers is that any genetic material (blood, pinched hair from an ear at marking of animals, buccal scrape of mucous membranes, urine, manure, semen, hair with hair follicles and even a few cells of embryos, etc.) can be used for researches at any age of animals. The value of this information is an early assessment of a genotype of an animal, that is, its genetic potential immediately after birth.
Using crossbreeding of different local populations of farm animals with imported ones has helped to improve the genetic potential of productivity of many populations of animals in very short term and the widespread artificial insemination has created conditions for economically useful programmable transmission of genes from parents to offspring. But now, as a result of intensive breeding and breed formation the accumulated reserve of variability has been reduced that can’t affect the possibilityofstrategic breeding. Intensive processes of "holsteinisation" and use of the limited number of sires of leading lines of this breed at moderate inbreeding and limitation of effective population size have led to the accumulation of "genetic load" in herds of local breeds–mutant variants of gene with lethal and semi-lethal effects.
Determination of hidden genetic abnormalities in cattle (BLAD – Bovine Leukocyte Adhesion Deficiency, CVM – Complex Vertebral Malformation, DUMPS – Deficiency of Uridine Monophosphate Synthase) using DNA diagnostics is carried out to prevent the accumulation of genetic load and reproductive losses. The vast number of spontaneous abortions and reasonsof early death of calves with birth defects is caused by gene mutations appearing phenotypically only if carriers of mutant alleles are both parents of a descendant. Identification of animals with heterozygous genotype as carriers of hidden abnormalities, is possible only if using proposed DNA technology.
Another type of testing breeding animals which is obligatory under law "On Livestock Breeding" is a cytogenetic analysis. In the selection and breeding work it is important not only to use methods for assessing the genetic potential of animals on the basis of productivity traits and availability of genetic diseases caused by mutations in specific genes. We must also take into account the sensitivity of animals’ genetic apparatus to different mutagenic environmental factors; it makes possible to select animals to improve genetic stability of their offspring and creating genetically stable populations at some farms that will significantly reduce the likelihood of chromosomal or genetic reconstructions in animals.
Reliable ways to assess genetic and population situation, genetic differences at interspecies, within species and individual level include a method of ISSR-PCR. Effective criteria for determining the impact of mutagenic environmental factors and selection factors on the structure of the investigated samples are implemented via this method and it is used as a tool for search of genetic loci associated with expression of the desired quantitative trait. This development is intended for use primarily in pig breeding for obtaining heterosis of offspring with high potential fattening and meat qualities.
As a result of long-term molecular genetic monitoring with use of own-created informative DNA markers in technology ISSR, RAPD, the confirmation of selection achievements in beekeeping was received– creating Khmelnytsky intra-breed type of Ukrainian Steppe bees with construction of unique genetic passport. The basic genetic criteria of "pure breed" of three bee species – Ukrainian, Carpathian and Grey Caucasian Mountain were determined, thus the degree of "pure breed"of bees can be determined accurately on the basis of morpho-metric and molecular genetic indicators. Using ISSR-S4 primer is able to identify the genome fragment of Ukrainian bees with size 950 bp, which is significantly associated with the expression of honey productivity; the research is carried out in this field.
Conducting DNA certification of bees to determine the purebred Ukrainian Steppe bees and Carpathian bees is a necessary part of the breeding work in beekeeping for the prevention and elimination of consequences of undesirable interbreed crossbreeding, linear consolidation, increase of traits of honey productivity.
In 2014,"Guidelines for morphological and genetic evaluation of Ukrainian bees" were formed and approved by the Ministry of Agrarian Policy of Ukraine as a result of long-term comprehensive studies on the genetics of honey bees.
Despite the difficult economic situation, a significant reduction in funding scientific support, reduction of scientific staff, low technological level of existing equipment, the work towards the development of effective technologies for the needs of the agricultural sector is conducted. The unique researches of peculiarities of genetic structure of major histocompatibility complex of cattle and pigs are carried out to identify animals with the best heredity for reproductive capacity and resistance to infectious diseases. Further study of protective and hygienic behaviour of bees, which is currently underway, will enable to improve breeding work in beekeeping with getting environmentally friendly products which can be exported and receive significant foreign exchange earnings to the state budget.
In general, livestock of Ukraine is the most important part of the socio-economic development and food security, as it is a manufacturer of biologically important products in the human diet. It is decidedly, that the progressive development of agriculture which defines export potential, quality of life and prosperity of citizens of Ukraine is impossible without the development of modern technologies and appropriate scientific support.

Full textAbstract:
Introduction. Peptic ulcer is one of the most prevalent diseases of the gastrointestinal tract. Stress factor is considered to have the highest impact on the development of ulcers, as it is present in almost all cases of onset and exacerbation of this disease. Acute stress ulcers occur with severe injuries, acute diseases of various organs, shock, a sharp drop in blood pressure, oxygen deficiency of body tissues, liver, kidney and others. Given the above facts, in the correction of stress-induced lesions of the gastric mucosa (GM) therapeutically, the target should consider not only reducing the aggression factors of gastric juice, but also the normalization of changes in protein and carbohydrate metabolism in GM. In this aspect, our attention was drawn to the domestic biotechnological preparation of placental cryoextract (CEP), which has a range of valuable biological effects. The aim is to study the effect of cryopreserved placenta extract on the state of protein-lipid metabolism in the gastric mucosa in a model of water-immobilization stress in rats. Materials and methods of research. The studies were performed on 28 nonlinear laboratory male rats weighing 200–220 g. Stress-induced gastric ulcer was modeled under water-immobilization stress (WIS) in rats according to the method of Takagi et al. To obtain the homogenate, the GM was perfused with cold (+ 4°C) buffer solution and homogenized at 3000 rpm (teflon/glass). The content of oxidatively modificated proteins (OMP) in GM was determined by Dubinina spectrophotometric method. The content of total lipids in the GM was determined spectrophotometrically by color reaction with sulfophosphovaniline reagent. Phospholipids (PL) were fractionated by the method of Svetashev and Vaskovsky. Research results. Evaluation of changes in protein metabolism in GM showed that the level of total protein in rats, which were preventively administered CEP before WIS, was almost comparable with that of intact rats, i.e., 50.1 ± 1.7 μg/mg tissue and 51.1 ± 1.3 μg/mg of tissue, respectively, which indicated the elimination of disorders of protein homeostasis with the introduction of the studied cryoextract. Studies of changes in total lipids and PL showed that the content of PL of animals treated with CEP was 26.9 ± 0.9%, which was not significantly different from that of intact animals (30.5 ± 0.9%) and, at the same time, it was by 7.3% higher (p < 0.001) as compared with animals who were administered esomeprazole. Conclusions. Prophylactic five-day administration of CEP to WIS leads to normalization of all evaluated indices, in particular, to increase of the total protein level by 29.0% (p <0.01), decrease of oxidatively modified proteins level by 20.6% (p <0.01), and the 2.3-fold increase (p <0.001) of the level of phospholipids in the total lipids pool.

Full textAbstract:
The effect of alcohol and/or zinc deficiency was evaluated in seven groups of pregnant rats and their pups. Females which had been acclimated to alcohol before breeding were fed liquid alcohol diets with either 14 or 0.1 ppm Zn. Comparisons were made with animals pair fed isocaloric liquid carbohydrate diets with the same Zn levels. Other comparisons were made by pair feeding a high zinc diet to a low zinc diet, and by feeding a high zinc diet ad lib. A reduced food intake and Zn deficiency affected maternal status by decreasing weight gain, liver Zn and plasma Zn concentration. Litter size, litter weight, and fetal liver and brain weight were decreased only in the alcohol zinc deficient group compared to adequately fed controls. The concentration and total quantity of fetal liver Zn were decreased due to a Zn deficiency. The combination of Zn deficiency and alcohol decreased only total Zn in fetal brain. The concentrations of protein, DNA, and RNA in fetal liver and brain were similar regardless of dietary treatment. The quantities of protein, DNA, and RNA were decreased in fetal liver due to Zn deficiency. ln fetal brain, only the combination of alcohol and Zn deficiency decreased total protein and RNA, while DNA was not affected. Although alcohol by itself had no effect on the above variables, its combination with a Zn deficiency did. In addition, there were 58 resorptions and 15 malformations seen in Zn deficient alcoholic dams compared with no more than 15 and 2, respectively, in any of the other groups. Teratogenesis caused by a Zn deficiency was increased with alcohol consumption.Ph. D.

Full textAbstract:
The most important tick-borne diseases (TBDs) occurring in Zambia that affect domestic animals, particularly cattle and small ruminants, are theileriosis (East Coast fever and Corridor disease), anaplasmosis (gall sickness), babesiosis (red water), and heartwater (cowdriosis). Of these, theileriosis is the most important, causing significantly more deaths than the other tick-borne diseases combined. Despite their importance, little is known about the occurrence and prevalence of haemoparasites in cattle in the communal areas of Zambia. Clinical signs and post mortem lesions are pathognomonic of mixed tick-borne infections especially babesiosis, anaplasmosis and East Coast fever (ECF). The main objective of this study was, therefore, to screen selected communal herds of cattle for tick-borne haemoparasites and identify the tick vectors associated with the high cattle mortalities due to suspected TBDs in the local breeds of cattle grazing along the banks of the Chambeshi River in Mungwi, Zambia. East Coast fever is endemic to the district of Mungwi, Northern Province, Zambia and vector control using acaricides has proved to be very costly for the small scale farmers. Also, Mungwi experiences increased cattle mortalities between December to March and May to July. All age groups of cattle are affected. A total of 299 cattle blood samples were collected from July to September 2010 from Kapamba (n=50), Chifulo (n=102), Chisanga (n=38), Kowa (n=95) and Mungwi central (n=14) in the Mungwi District, Northern Province, Zambia. Ticks were also collected from the sampled cattle from April to July 2011. DNA was extracted and the parasite hypervariable region of the small subunit rRNA gene was amplified and subjected to the reverse line blot (RLB) hybridization assay. The results of the RLB assay revealed the presence of tick-borne haemoparasites in 259 samples occurring either as single or mixed infections. The most prevalent species present were the benign Theileria mutans (54.5%) and T. velifera (51.5%). Anaplasma marginale (25.7%), Babesia bovis (7.7%) and B. bigemina (3.3%) were also detected in the samples. Nine percent of the samples tested negative for the presence of haemoparasites. In a number of samples (4%) the PCR products failed to hybridize with any species-specific probes but hybridized only with the genus-specific probes which could suggest the presence of a novel species or variant of a species. Of the four Theileria species known to occur in Zambia (T. parva, T. mutans, T. velifera and T. taurotragi), T. parva is the most economically important, causing Corridor disease in the Southern, Central, Lusaka and the Copper-belt provinces, while causing ECF in the Northern and Eastern provinces of Zambia. In our study, only one sample (from Kapamba) tested positive for the presence of T. parva. This was an unexpected finding; also because the tick vector, Rhipicephalus appendiculatus, was identified on animals from Kowa (14%), Chisanga (8.5%), Chifulo (6%) and Kapamba (1.4%). We can only speculate that the RLB hybridization assay may not have been able to detect the parasite in the animals sampled due to a too low parasitaemia. The samples should also be subjected to the T. parva specific real-time PCR assay to determine a more accurate T. parva prevalence in cattle in the Mungwi district, Northern Province. In Zambia, Babesia bovis and B. bigemina are recognized as being of economic importance in cattle. In our study, B. bovis was present in 7.7% of the sampled animals and B. bigemina in 3.3% of the animals. We detected B. bovis in all of the five sampled areas with the highest detection in Mungwi central (14.3%) and Kowa (10.5%). As expected, the tick vector Rhipicephalus (Boophilus) microplus was identified from animals from all of these areas. Babesia bigemina was only reported from Kowa (10.5%). The most abundant ticks identified from the sampled animals from Kowa were Rhipicephalus (Boophilus) decoloratus (36.3%) and Rhipicephalus (Boophilus) microplus (8.8%). These tick vectors have been implicated in the transmission of B. bigemina. Our findings are in concordance with results obtained by other authors who have speculated that an increase in the detection of B. bovis may indicate that B. bovis is becoming endemic in this part of the country. This could be due to uncontrolled movement of cattle that frequently occurs within Zambia. Heartwater (cowdriosis) is caused by Ehrlichia ruminantium, a rickettsial disease that affects domestic and wild ruminants. In Zambia, heartwater is mainly a disease of cattle, although outbreaks in sheep and goats have been reported and recorded. In our study, only one sample (from Kapamba) tested positive for the presence of E. ruminantium even though Amblyomma variegatum ticks were identified from 52.9% of the sampled animals from all study areas. The cattle sampled in our study are not regularly dipped and no game has been spotted in cattle grazing areas. It is possible that these cattle may have attained a state of endemic stability to heartwater. It is also possible that the RLB hybridization assay may not have been sensitive enough to detect E. ruminantium infections if the parasitaemia was very low. Samples should also be subjected to the E. ruminantium-specific pCS20 real-time PCR assay to determine more accurately the E. ruminantium prevalence in cattle in the Mungwi district, Northern Province. Anaplasma marginale (the causative agent of bovine anaplasmosis) has previously been shown to be present in all the provinces of Zambia and is the only Anaplasma species of importance to cattle in Zambia. In our study, 25.7% of the sampled cattle tested positive for A. marginale; it was detected in all areas except Chisanga. Amblyomma variegatum was identified from 52.9% of the sampled cattle, and Rhipicephalus (Boophilus) microplus from 12.1% of the cattle. Rhipicephalus (Boophilus) microplus has been incriminated as being a vector of A. marginale. Furthermore, three samples (from Kowa) tested positive for the presence of Anaplasma centrale. To our knowledge, no vaccination regime using A. centrale is being conducted in the Mungwi district of Zambia. The presence of A. centrale is, therefore, an interesting finding. The results of our study suggest that the cause of cattle mortalities in Mungwi during the winter outbreaks is mainly due to A. marginale, B. bovis and B. bigemina infections. This was confirmed by the results of the RLB hybridization assay, clinical manifestation of the disease in the affected cattle (own observation) and the tick species identified on the animals. It appears that in Mungwi, babesiosis due to B. bovis mostly infects cattle above one year of age. Calves appear to be less affected by B. bovis infection. There is need for further epidemiological surveys in Mungwi district, Northern Province, Zambia to get a better understanding of the epidemiology of these tick-borne haemoparasites affecting cattle. We conclude that integrated control policies should be developed to take account of multi-species pathogen communities that are commonly associated with clinical and sub-clinical TBD infections in Zambia.Dissertation (MSc)--University of Pretoria, 2012.

Full textAbstract:
Abstract Little is known about a) the differences in allergic and respiratory diseases between the Finnish and Russian populations, and the environmental factors associated with those differences, and b) exposure to pollen grains indoors and the efficiency of penetration of pollen from outdoor to indoor air. This thesis is based on a cross-sectional population-based epidemiological study conducted in Imatra (Finland) and Svetogorsk (Russia) in 2003 and a rotorod-type-sampler-based pollen study conducted in the province of South Karelia (Finland) between 2003 and 2004. The prevalence of allergic diseases was higher among Finnish than Russian schoolchildren. The symptoms among allergic children were more severe, and the occurrence of respiratory infections was in general more frequent in Russia than in Finland. In the logistic regression analyses the risk of asthma was particularly related to high maternal smoking exposure, and the risk of the common cold was related to high combined parental smoking during infancy (adjusted OR 1.83, 95% CI 1.06–3.17) in Finnish children. Among Russian children, allergic conjunctivitis was related to maternal smoking, while the common cold was inversely related to paternal and parental smoking (0.60, 0.37–0.98 and 0.31, 0.11–0.83, respectively) during the study period. The risk of asthma was inversely related to any indoor dog-keeping in Finland (0.35, 0.13–0.95), whereas in Russia the risk of asthma was increased in relation to combined indoor cat exposure during infancy and the study period (4.56, 1.10–18.91). The concentrations of pollen grains decreased from abundant (0–855 pollen grains per cubic meter, pg/m3) to low (0–3 pg/m3), when moving from outdoors to indoors and further. The differences in diseases and symptoms in these two closely related populations could be ascribed to differences in culture, exposures, diagnostic criteria and treatment. The concentrations of pollen in indoor air during the flowering period were mostly on a level high enough to cause reactions in only the most sensitive subjects. The results suggest that more efforts should be directed to reducing parental smoking, to studying the role and effects of nationally different animal exposures in childhood, and to assessing the importance of different penetration routes of pollen grainsTiivistelmä Suomen ja Venäjän välisistä allergioiden ja hengitystietulehdusten esiintymiseroista ja esiintymiseen vaikuttavista ympäristötekijöistä tiedetään varsin vähän. Myös tutkimuksia siitepölyille altistumisesta sisätiloissa ja siitepölyjen tunkeutumiskyvystä ulkoilmasta sisäilmaan on niukasti. Tutkimus yhdistää sekä lääketieteellisen että luonnontieteellisen tutkimusalan tutkimustraditiot sekä atooppisten sairauksien ja/tai hengitystietulehdusten tärkeimpien määrittäjien tarkastelun yhdeksi tutkimuskokonaisuudeksi. Väestö- ja kyselylomakepohjainen poikkileikkaustutkimus toteutettiin Suomen ja Venäjän rajan molemmin puolin sijaitsevissa Imatran ja Svetogorskin kaupungeissa vuonna 2003. Tutkimusväestö koostui 512 suomalaisesta ja 581 venäläisestä 7–16-vuotiaasta koululaisesta (osallistumisaste 79 %). Rotorod-tyyppisen keräimen käyttöön perustuva siitepölytutkimus toteutettiin erilaisissa ulko- ja sisätiloissa Lappeenrannan ja Imatran kaupungeissa, Rautjärven kunnassa ja valtatie 6:lla vuosina 2003 ja 2004. Atooppisten sairauksien esiintyvyys oli runsaampaa suomalaisten koululaisten keskuudessa. Sitä vastoin allergisten lasten kokemat oireet olivat voimakkaampia ja hengitystietulehdusten esiintyvyys oli runsaampaa venäläisten koululaisten keskuudessa. Astmariski kytkeytyi erityisesti äidin runsaalle tupakoinnille altistumiseen raskauden (vakioitu OR 3.51, 95 % luottamusväli 1.00–12.3), ensimmäisen elinvuoden (3.34, 1.23–9.07) ja tutkimuksen aikana (3.27, 1.26–8.48). Nuhakuumeen riski oli suurentunut suomalaisten koululaisten keskuudessa, jotka olivat altistuneet molempien vanhempien runsaalle tupakoinnille ensimmäisen elinvuoden aikana (1.83, 1.06–3.17). Äidin tupakoinnille ensimmäisen elinvuoden (4.53, 1.49–13.8) ja tutkimuksen aikana (2.82, 1.07–7.44) altistuneilla venäläisillä oli suurentunut allergisen silmän sidekalvotulehduksen riski. Tutkimuksen aikainen isän ja vanhempien tupakointi vähensi nuhakuumeen riskiä (0.60, 0.37–0.98; 0.31, 0.11–0.83) Venäjällä. Suomessa koiranpito sisätiloissa vähensi astmariskiä (0.35, 0.13–0.95), vastaavasti Venäjällä raskauden jälkeinen sisätiloissa tapahtuva kissa-altistus lisäsi koululaisten astmariskiä (4.56, 1.10–18.91). Siitepölyjen pitoisuudet pienenivät siirryttäessä ulkoa (0–855 siitepölyhiukkasta ilmakuutiossa; sp/m3) sisätiloihin (0–17 sp/m3). Ympäristöaltisteisiin ja sairauden ennusteeseen vaikuttavat sekä kansallinen kulttuuri ja vakiintuneet tavat, että erot diagnosointikriteereissä, yleisessä tautitietoisuudessa ja lääkkeiden saatavuudessa. Näin ollen altisteiden voimakkuus ja kesto sekä terveysvaikutukset voivat vaihdella merkittävästi lähellä toisiaan sijaitsevien alueiden välillä. Siitepölypitoisuudet sisätiloissa olivat pääosin tasolla, jolle altistuminen aiheuttaa oireita vain kaikkein herkimmille allergisille. Tutkimuksen tulosten mukaan lisää voimavaroja tulisi suunnata passiiviselle tupakoinnille altistumisen vähentämiseen erityisesti yksilökehityksellisesti herkkien varhaisvaiheiden aikana, kansallisten eläinaltistuserojen terveysvaikutusten selvittämiseen sekä siitepölyjen erilaisten kulkeutumisreittien merkityksen tutkimiseen

The aim of this study was to determine the serologic and molecular occurrence of Rickettsia spp., Ehrlichia spp., Babesia spp. and Hepatozoon spp. in ticks and domestic and wild animals from two conservation units in the city of Natal, Rio Grande do Norte State, Brazil. The collection period was between October 2012 and August 2013. Serum samples were tested against Rickettsia spp. antigens and Ehrlichia canis by Indirect fluorescent antibody test. Tissue samples and ticks were processed for molecular detection of the pathogens. Twenty-seven marsupials and four rodents were captured, and up to three animals of each species were euthanized. In addition, serum samples from 155 domestic animals: 53 cats living inside the units, 29 dogs domiciled around the areas and 73 dgos of the Zoonosis Control Center of the City (ZCC). Twenty dogs from ZCC were also euthanized and samples of spleen were obtained. Antibodies to at least one of the Rickettsia species tested were detected in six Didelphis albiventris and in one Rattus rattus; 17% (17/102) of the dogs presented antibodies to E. canis and 13% (20/155) of all tested domestic animals (dogs and cats) were seropositive for Rickettsia spp. antigens. Three species of ticks (Amblyomma auricularium, Ixodes loricatus and Ornithodoros mimon) were collected and one A. auricularium was positive for Rickettsia amblyommii by PCR. Two D. albiventris spleen samples amplified PCR products for Ehrlichia spp. Spleen samples from three D. albiventris and spleen and lung sample from one Necromys lasiurus were positive for Babesia spp. by PCR test. Among the 20 spleen samples from dogs subjected to molecular analysis, eight were positive by PCR for E. canis and two for H. canisO objetivo deste estudo foi determinar a ocorrência sorológica e molecular de Rickettsia , Ehrlichia , Hepatozoon e Babesia em carrapatos e mamíferos silvestres e domésticos, provenientes de duas unidades de conservação ambiental (UC) na cidade de Natal, Rio Grande do Norte, Brasil. O período de coleta foi de outubro de 2012 a agosto de 2013. Os soros foram testados contra antígenos de Rickettsia spp. e Ehrlichia canis através da reação de imunofluorescência indireta. Amostras de tecido e carrapatos foram processadas para a detecção molecular dos patogenos. Foram capturados 27 marsupiais e quatro roedores para coleta de sangue, destes foram eutanásiados ate três animais de cada espécie e coletadas amostras de baço e pulmão. Paralelo, amostras de soro de 155 animais domésticos: 53 gatos que viviam nas UCs, 29 cães domiciliados no entorno das areas e 73 cães do Centro de Controle de Zoonoses do município, dos quais 20 tiveram amostras de baço coletadas. Foram detectados anticorpos para, pelo menos, uma das espécies de Rickettsia testadas em seis Didelphis albiventris e em um Rattus rattus , e 17 % (17/102) dos cães apresentaram anticorpos anti- E. canis e 13% (20/155) de todos os animais domésticos (cães e gatos) foram soropositivos para antígenos de Rickettsia spp. Três espécies de carrapatos (Amblyomma auricularium , Ixodes loricatus e Ornithodoros mimon ) foram coletadas e um A. auricularium foi positivo para R. amblyommii pela PCR. Duas amostras de baço de D. albiventris amplificaram produtos de PCR para Ehrlichia spp. e amostras de baço de três D. albiventris e baço e pulmão de um Necromys lasiurus foram positivas para Babesia spp. pela PCR. Entre as 20 amostras de baço de cão submetidas a análises moleculares, oito foram positivas na PCR para E. canis e duas para H. canis

Full textAbstract:
The study of the diversity of the parasitophauna in wild and domestic animals from various natural and anthropic biotopes of the Republic of Moldova allowed revealing that 80,8% of such animals were infested with mix forms of parasites, in diverse associations from two till five parasite agents. The obtained results suggest that the parasitophauna of the wild animals (deers, roedeers, bisons) roughly correspond to the parasitophauna of the domestic animals (cattle, sheep) pasturing in the neighboring regions. The analysis of the parasitological data show that the parasitic agents could be attributed into two groups: those obligate for wild animals and those common for the wild and wild animals. The high level of infestation of the wild ruminants with fasciolas, dicrocelium, intestinal and pulmonary strongyles, protista as well as the presence of the intermediary and complementary hosts demonstrate again that these take part in maintaining the epizootic chain of diseases and have a huge impact on infesting the domestic animals. In this way, the ambient environment plays an important role in maintaining the epizootic chain of the parasitic infections. The recent parasitic research conducted in domestic and wild animals in Moldova reveal the conversed situation – the wild and domestic animals are reciprocally infested by various parasitic agents while pasturing on the same territory.

Ectoparasites of domestic dogs continue to be regularly recorded in the city. Young animals under one year of age are most susceptible to the infection. The purpose of our research was to study the spread of ectoparasites in domestic dogs under one year of age in Moscow. The study was carried out on 543 dogs admitted to a veterinary clinic in 2018–2022. The animals were both with clinical manifestations of diseases and clinically healthy. All animals were examined, the coat condition was determined, and microscopy of ear exudate, superficial and deep skin scrapings, trichoscopy, and a wet paper test were performed. Ectoparasites were found in 30.9% of examined dogs under the age of one year. Ixodid ticks (9.2%), Demodex sp. (8.3%), Ctenocephalides sp. (5.3%), and Cheyletiella yasguri (4.0%) were most frequently diagnosed. Ticks Otodectes cynotis (2.2%) and Sarcoptes canis (1.3%) and biting lice Trichodectes canis (2.0%) were found less frequently. Combined infection by several types of ectoparasites was diagnosed in 8 cases (1.5%). Having compared our data with those previously published, it becomes obvious that the ectoparasite infection of young domestic dogs under the age of one year remains high in Moscow.

This review aimed to identify the general characteristics of , mechanism of action, types and uses of antimicrobial peptides in animals, antimicrobial peptides were lass of small peptides that widely exist naturally, they varied greatly in structure, composition are found in the animal's species, and were standard structural features, twenty to sixty residue long, cationic and amphipathic peptides, have a positive charge that interacted with negatively charged molecules on the bacterial cell surfaces, a have an expansive field of inhibitory effects and were made as the first line of protection by both multicellular organisms. An essential component of the innate immune method of various organisms can have broad movement to instantly destroy bacteria, parasites, yeasts, fungi, viruses, and even cancer cells, Several antimicrobial peptides were expressed in the gastrointestinal mucosa of the animals where they can modulate innate immune responses and the intestinal microbial, act some protective microbial species and modulate an immune response. Its interactions with innate immunity and the intestinal microbial reveal attractive drug targets, act as a new therapeutic approach against gastrointestinal infections, damage, and inflammations, and modulate obesity and metabolic diseases. In addition, its acts as a biomarker of gastrointestinal diseases. They have been useful parts of the host's defense systems for a long time. Because microbes become resistant to antimicrobial peptides more slowly than to traditional antibiotics, they could be used as alternative treatments in the future. Several thousand antimicrobial peptides have been isolated from microorganisms, plants, insects, crustaceans, creatures, and even humans. Conclusion: Antimicrobial peptides are small proteins found in plant and animal species. They are the first defense against infections caused by microorganisms. and work against a wide range of bacteria, fungi, and viruses, both gram-positive and gram-negative. They are related together to innate immunity and adaptive immunity.

Full textAbstract:
This work is based on helminthological data of amphibians, collected since 2013 until 2020, in the Republic of Moldova. The investigations on anura amphibians were conducted in the laboratory of Parazitology and Helminthology of the Institute of Zoology. One of the most common parasitic diseases in ruminants is fasciolosis, caused by the trematode Fasciola hepatica species. The results of parasitological research showed that adult cattle were infected with fascioles in 66.4% of cases, and young cattle - in 46.1% of cases. This is largely due to the grazing of animals of different species and ages in limited areas.The presence of the trematode species Haplometra cylindracea was established in 78% of cases in the amphibians in the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis). The results of laboratory helminthological investigations have shown that the relationships between the Fasciola hepatica miracidium and the Haplometra cylindracea miracidium are antagonistic. Amphibians of the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis) infested with Haplometra cylindracea tremateda may play an important role in the prophylaxis of fasciolosis.

The purpose of this research was to obtain current data on protozoosis and most important helminthozoonosis in domestic cats in Moscow. Coproovoscopic examinations were performed in 2022–2023 to study two age groups of domestic cats: 316 kittens aged under one year in 6 administrative districts, and 570 cats aged over one year in 9 administrative districts of Moscow. Domestic cats over 1 year were infected with helminthiasis: nematode species Toxocara cati with maximum prevalence of 15%, species Toxascaris leonina with the prevalence of up to 10%, species Uncinaria stenocephala with the prevalence of 4%, cestode species Dipylidium caninum with the prevalence of 4% and the cestode helminth Taenia spp. with the prevalence of 5.5%, protozoan parasites Isospora felis with the prevalence of up to 5%, and Giardia spp. with the prevalence of up to 5%. The Toxocara cati infection in domestic kittens under one year reached its maximum value with the prevalence of 26.08%. Toxascaris leonina was not found in the kittens under one year. Dipylidium caninum infection in the kittens reached maximum prevalence of 7.2%. Taenia spp. was not found in the domestic kittens under one year of age. Current obtained data on most important feline helminth infections will make it possible to develop and propose guidelines for health improvement and prevention of invasive diseases in animals and avoidance of parasitic contamination of social facilities in external environment in Moscow.

Parasitic arachnoses (sarcoptoses, psoroptosis, otodectoses, demodicoses, etc.), through their serious evolution, have anthroponotic characters with economic, sanitary and social implications. Infestation with arachnids diminishes considerably the quality of life of domestic animals, causing them metabolic diseases, scratching, stress, allergies and leads to the development of bacterial dermatoses. Fipronil is an acaricidal and stable remedy that lasts longer. The purpose of this study was the control of the efficacy of acaricide of the Demoged-Forte pharmaceutical product in order to combat the ectoparasites in cats and dogs, conditioned by the company Euro Prime Farmaceuticals LLC. The product is very effective in combating sarcoptoses and notoendrosis (98-100%) in dogs and cats. In the treatment of otodectoses, the product demonstrated an efficacy of 99%, and in demodicoses was found a result of about 90-92%. Thus, DemogedForte independently, without complexs therap, demonstrated a high efficacy in the treatment of sarcoptoses, notoendrosis, otodectoses and demodicoses, ranging between 92-99%, which confirms that we can treat animals without putting their lives in danger.

Full textAbstract:
Fossil fuels are an exhaustible resource on Earth, and their use pollutes the environment massively. The population of the planet has grown a lot, and for the production of domestic hot water, to ensure a decent standard of living, it is necessary to consume increasing quantities of fossil fuels. The very high level of greenhouse gases released into the atmosphere leads to an increase in average of annual temperature and climate change. Climate change is manifested by the melting of the ice caps, which has the consequence of increasing the level of the seas and oceans. Climate change also leads to extreme weather events such as floods, heat waves or the appearance of arid areas. Risks to human health have increased through deaths caused by heat or by changing the way some diseases are spread. Risks also exist for flora and wildlife due to rapid climate change.Many species of animals migrate, and other species of animals and plants are likely to disappear. Climate change also leads to costs for society and the economy due to damage to property and infrastructure, which have been more than 90 billion euros in the last 30 years, just because of the floods. In order to reduce the effects of environmental pollution, ecological energy production solutions need to be expanded. The article presents the creation of an experimental stand of a Solar - TLUD stove combined system for the production of domestic hot water in a sustainable way. TLUD is the acronym for "Top-Lit UpDraft". The advantage of the combined heat system is that it can provide thermal energy both during the day and at night. If the atmospheric conditions are unfavorable (clouds, fog) and do not allow the water to be heated only with the solar panel, TLUD gas stove can be used to supplement the energy. The TLUD stove has low Carbon Monoxide (CO) and Particulate Matter (PM) emissions. After gasification, about 10% of the carbon contained in the biomass is thermally stabilized and can be used as a "biochar" in agriculture or it can be burnt completely, resulting in very little ash. The stand is composed of a solar thermal panel, a TLUD stove, a boiler for hot water storage and an automation system with circulation pumps and temperature sensors. To record the experimental results, a data acquisition board was used, with which data were recorded from a series of temperature and flow transducers located in the installation. Experimental results include diagrams for temperature variation, available energy and heat accumulated in the boiler.

Full textAbstract:
It marked 120 years since the birth of Tatyana Semenovna Skarbilovich, the founder of Soviet and Russian phytonematology and helminthology (January 24, 1904). While in the Moscow University, T. S. Skarbilovich studied in a helminthological group organized by Academician K. I. Skryabin in 1924. In 1926 to 1933, T. S. Skarbilovich mainly worked in zoohelminthology. During this period, she published 20 scientific papers on helminth fauna of domestic and wild animals, as well as biology of some helminths. T. S. Skarbilovich stood at the origins of phytohelminthology in our country. From 1929 until the end of her life (1988), T. S. Skarbilovich’s scientific activity was associated with the All-Union Institute of Helminthology where she headed the Laboratory of Phytohelminthology for more than 25 years, and then continued to work as a consulting Professor. Tatyana Semenovna studied dozens of phytohelminth species that cause nematode diseases of agricultural, medicinal, and ornamental plants. The results of these studies were presented in the monograph that was translated into Chinese and published in the PRC. An in-depth and detailed study of biology and ecology of, and control measures against, the beet cyst nematode formed the basis of her doctorate thesis. She was the author of over 100 scientific papers. Bibliography "Domestic literature on nematodes of plants, insects, soil and aquatic environments for 1874 to 1980" published by T. S. Skarbilovich was translated into English in India.

Full textAbstract:
Geohelminth infections are a complex and multifaceted problem that attracts the
attention of both medical doctors and veterinarians, as well as scientists. They
are the most common parasitic diseases. The annual number of recorded cases
of geohelminthiasis in humans in the Kursk Region and conditions conducive
to their spread have determined the timeliness of studies on contamination of
environmental objects with geohelminth eggs. Analysis of the study results showed
that the contamination of environmental objects with parasitic agents was 8.4%.
Ascaris and Toxocara eggs were recorded in the samples. 7.9% of the examined soil
samples, 13.7% of the manure and 3.7% of the runoff samples from the territories
were positive for pathogens of geohelminthiasis. Depending on the season of the
year, the indicators of environmental objects contaminated with geohelminth eggs
were not the same. There was an increase in contamination of the soil and runoff from territories almost twice in the autumn period (prevalence, 12.6%) as compared
with the summer period (EO 6.5%). Thus, environmental objects contaminated
by parasitic agents indicate the circulation of geohelminthiasis pathogens among
domestic animals in the study territories and a risk of infection with larval toxocariasis
and ascariasis for the population.

Full textAbstract:
Foot-and-mouth disease (FMD), a highly infectious viral disease of cloven-hoofed animals, is economically the most important disease of domestic animals. Although inactivated FMD vaccines have been succesfully used as part of comprehensive eradication programs in Western Europe, there are a number of concerns about their safety. In this proposal, we have attempted to develop a new generation of FMD vaccines that addresses these concerns. Specifically we have cloned the region of the viral genome coding for the structural proteins and the proteinase responsible for processing of the structural protein precursor into both a DNA vector and a replication-deficient human adenovirus. We have demonstrated the induction of an FMDV-specific immune response and a neutralizing antibody response with the DNA vectors in mice, but preliminary potency and efficacy studies in swine are variable. However, the adenovirus vector induces a significant and long-lived neutralizing antibody response in mice and most importantly a neutralizing and protective response in swine. These results suggest that the empty capsid approach is a potential alternative to the current vaccination strategy.
