Abstract:

RESUMO A tartaruga-verde, Chelonia mydas, apresenta distribuição cosmopolita. No Brasil, ocorre na costa, porém desova em ilhas oceânicas. A helmintofauna de tartarugas-verdes é diversificada, podendo-se dizer que tem a maior diversidade comparada com outras espécies de tartarugas. Objetivou-se avaliar aspectos ecológicos da comunidade de helmintos gastrointestinais e relacionar com a condição corporal de tartarugas-verdes recolhidas no litoral do Espírito Santo. Foram utilizados 36 exemplares juvenis da espécie C. mydas. O trato gastrointestinal foi separado e dividido em porções: esôfago/estômago, intestino delgado e intestino grosso. Cada porção foi inspecionada à procura de parasitos, e os exemplares encontrados foram separados para posterior identificação. Das 36 tartarugas avaliadas, 34 estavam parasitadas por helmintos (94,44%), com um total de 10.734 helmintos. Foram encontradas 18 espécies de trematodas pertencentes a quatro famílias. A riqueza de espécies encontrada foi de 4,29±2,19 (1-10) e a intensidade média de infecção foi de 315,64±281,83 (2-994) helmintos. Os parasitos mais prevalentes foram Cricocephalus albus, Metacetabulum invaginatum e Neoctangium travassosi, ambos com 61,11% (22/36), Pronocephalus obliquus com 33,33% (12/36), e Glyphicephalus lobatus com 30,55% (11/36). O helminto mais abundante foi M. invaginatum com 70,63 helmintos/animal, seguido de C. albus com 58,77 helmintos/animal e N. travassosi com 41,75 helmintos/animal.

Abstract:

A total of 213 faecal samples were collected from four abattoirs and households to determine the prevalence of helminthes infections in exotic and indigenous goats in Port Harcourt, South-South, Nigeria. The study revealed that out of 153 exotic goats (Red Sokoto) Capra hircus, 112 were infected with various species of gastrointestinal helminths; out of 60 indigenous goats (West African dwarf) Capra hircus, 49 were also infected with various types of gastrointestinal helminths. The formol-ether concentration method was used to analyse the specimens. The study revealed that an overall prevalence of (75.5%) was recorded, out of which 57 (76.0%), 55 (70.5%), and 49 (81.6%) were recorded for exotic goat in the months of May–September, 2010, exotic goat in the months October 2010–February, 2011 and for indigenous goats, respectively. The overall prevalence amongst the infected animals was not statistically significant (P>0.05). Species of helminthes revealed from the study were, Haemonchus, Strongyloides, Chabertia, Trichuris, Ostertagia, Bunostomum, Trichostrongyloida, Ascaris, Tenia, Avitelina, Fasciola, Eurytrema, Gastrothylax, Schistosoma, and Dicrocoelium.

Abstract:

Tests of the antiparasitic agent Albicomum 10% VK were carried out in the Uvinsky and Zavyalovsky districts of the Udmurt Republic on animals spontaneously infested by the association of helminthiases. Animals of the first group were infested with fasciolous-strongylatosis invasion, the second - with mixed invasion of dicroceliosis + gastrointestinal strongylatosis, cows spontaneously infested with three types of helminths (fascioliasis + dicroceliosis + gastrointestinal strongylatosis) were in the third experimental group. Control groups were also formed with the corresponding associations of parasites, in which the intensity and extensity of infestation remained at a high level throughout the entire experiment. In the first (fascioliasis + gastrointestinal strongilatoses) and in the second (dicroceliosis + gastrointestinal strongylatoses) groups, all treated animals were completely freed from helminths on the 45th day. The extensibility of the drug was 100%. On the 90th day after the treatment, the effectiveness of the drug decreased by 10%. In case of fasciolous- dicrocelious-strongylatous association, the drug showed low efficiency. In 1 g of feces of the treated animals, an average of 9.7 eggs of trematodes were found. In production trials, Albicomum 10% VK showed the highest efficiency (90%) in two-component helminthoses.

El objetivo del estudio fue estimar la prevalencia de helmintiasis gastrointestinal en cuyes de producción familiar-comercial del distrito de Matahuasi, provincia Concepción, Junín-Perú; así como determinar los géneros y especies de helmintos gastrointestinales; carga y tipo de parasitismo (monoparasitismo, biparasitismo o poliparasitismo), grado de concordancia entre el recuento diferencial de parásitos al examen post mortem vs las técnicas coprológicas y la sensibilidad/especificidad de las técnicas coprológicas en el diagnóstico de la helmintiasis gastrointestinal en cuyes. Se adquirieron 262 tractos gastrointestinales de centros de acopio de cuyes provenientes de crianzas familiar-comercial entre enero y marzo de 2017. Se evaluaron los segmentos de estómago, intestino delgado e intestino grueso para determinar la carga parasitaria y se colectaron muestras fecales del recto. El procesamiento de muestras se realizó mediante el recuento diferencial de parásitos al examen post mortem y técnicas coprológicas complementarias (Flotación y Dennis modificado). La prevalencia de helmintos gastrointestinales fue de 82.8 ± 4.6%. Se identificaron Paraspidodera uncinata, Capillaria spp, Trichostrongylus axei y Trichuris spp con frecuencias de 74, 34, 6.1 y 3.4%, respectivamente. El número promedio de helmintos por animal fue 24.7, donde P. uncinata, Capillaria spp, Trichostrongylus axei y Trichuris spp mostraron promedios de 23.5, 8.7, 1.2 y 1.2, respectivamente. El monoparasitismo fue 50.4% y el biparasitismo fue 30.2%. El grado de concordancia entre las técnicas coprológicas presentó valores de Kappa (K) igual a 0.19 y 0.13 indicando que fue del tipo pobre. Las técnicas de flotación y Dennis modificado presentaron una sensibilidad de 39.6 y 29.5% y una especificidad de 89.9 y 93.3%, respectivamente.

Abstract:

The purpose of the research is studying the epizootic situation on major helminthoses in cattle under different management systems in Georgia. Materials and methods. The epizootic situation in Georgia on major helminthoses in cattle subject to management systems and the altitudinal zonation of areas location was studied by coprological examination of animals. In 2014–2018, the cattle aged over 2 years held on pasture from March-April until November was studied in homesteads of 59 districts. Similar studies were performed at 19 farms owned by limited liability companies, homesteads and entrepreneurs. The livestock there is presented by Schwyz and Holstein; all processes of care, feeding and milking are mechanized. Results and discussion. Currently, the major helminthoses in pasture cattle in Georgia are paramphistomidosis, fasciolosis, dicrocoeliosis, gastrointestinal strongylatosis and dictyocaulosis which infect 67.5% of the examined cattle. Paramphistomidosis and fasciolosis are found in 59.7 and 21.5% of the examined cattle respectively. With increasing elevation of the altitudinal zonation, the paramphistomidosis and fasciolosis prevalence rates reduce. In case of paramphistomidosis, the infection ranges from 78.4% (low elevation from 0 to 200 m above sea level) to 23.9% (the subalpine area from 1901 to 2300 m above sea level), and in case of fasciolosis, 28.2–8.1% respectively. The rest species of helminths infected cattle to a lesser degree. Dicrocoelium sp. was found in 2.7% of animals, gastrointestinal Strongylata in 6.3%, and Dictyocaulus sp. in 3.9%. Paramphistomum spp., Fasciola sp. and gastrointestinal Strongylata infected 1.2% of the examined cattle in the farms with stabled cattle.

Abstract:

A exploração na ovinocultura vem contribuindo ao longo dos anos no agronegócio brasileiro e para a economia mundial, concentrando seus rebanhos principalmente nas regiões Nordeste e Sul. Entretanto, mesmo com a crescente demanda de produtos como a carne, leite e lã, ainda se apresentam limitações pelas inúmeras condições de manejo sanitário. Devido as parasitoses gastrointestinais diretamente interferirem na sanidade dos rebanhos, objetivou-se avaliar a ocorrência de parasitas gastrointestinais em rebanhos ovinos dos municípios de Canoinhas e Três Barras, Estado de Santa Catarina. Entre maio e junho de 2019, foram examinadas, pela técnica de Gordon e Whitlock e coprocultura, amostras fecais de 103 ovinos puros e mestiços e de diferentes faixas etárias procedentes de quatro rebanhos. As variáveis (raça, idade, gênero e rebanho) foram analisadas pelos testes de Student e qui-quadrado. Observou-se em 67,96% dos ovinos amostrados a presença de oocistos do gênero Eimeria e 80,58% de positivos para ovos de helmintos gastrointestinais, dos quais a ordem Strongylida e os gêneros Trichuris sp., Toxocara sp. e Moniezia sp. estavam presentes. Dentre estes, 64,08% estavam com infecção mista por helmintos e protozoários. As larvas identificadas das coproculturas indicaram infecções pelos gêneros: Haemonchus, Oesophagostomum, Trichostrongylus Cooperia e Ostertagia. O grau de infecção parasitária apresentou diferença estatística para os helmintos da ordem Strongylida quando comparados os borregos com animais adultos (p=0,011). Os gêneros Haemonchus e Trichostrongylus mostraram ser os mais importantes e abundantes no parasitismo gastrointestinal detectado nos ovinos do Planalto Norte Catarinense.

Abstract:

Domestic birds have significant contributory role in national economy and social world. In Kano, especially in rural areas farmers and agriculturists still depend economically on these animals. The study was conducted to find out various gastrointestinal parasites and their prevalence in domestic birds using Specimens processed through Sedimentation and Floatation method.The result shows that there is high rate of infection in pigeons. On the other hand a low rate of infection was observed in chickens. The helminthes found in the domestic birds were of five species: S. intercalatum, Paragonimus sp, H. nana, Taenia spp and S. stercoralis larva. This study indicated that there was a significant difference in the prevalence of helminths between pigeons and chickens. It indicated that pigeons are most affected among districts.

Abstract:

Th2 cells drive protective immunity against most parasitic helminths, but few mechanisms have been demonstrated that facilitate pathogen clearance. We show that IL-4 and IL-13 protect against intestinal lumen-dwelling worms primarily by inducing intestinal epithelial cells (IECs) to differentiate into goblet cells that secrete resistin-like molecule (RELM) β. RELM-β is essential for normal spontaneous expulsion and IL-4–induced expulsion of Nippostrongylus brasiliensis and Heligmosomoides polygyrus, which both live in the intestinal lumen, but it does not contribute to immunity against Trichinella spiralis, which lives within IEC. RELM-β is nontoxic for H. polygyrus in vitro but directly inhibits the ability of worms to feed on host tissues during infection. This decreases H. polygyrus adenosine triphosphate content and fecundity. Importantly, RELM-β–driven immunity does not require T or B cells, alternative macrophage activation, or increased gut permeability. Thus, we demonstrate a novel mechanism for host protection at the mucosal interface that explains how stimulation of epithelial cells by IL-4 and IL-13 contributes to protection against parasitic helminthes that dwell in the intestinal lumen.

Abstract:

Gastrointestinal parasitic infections in dogs and cats are a common problem in the clinical setting. Ascarids, hookworms, whipworms and tapeworms should be eliminated on a regular basis, not only to avoid possible health implications on the host itself, but also for the zoonotic potential of certain helminthes (ascarids, hookworms, Echinococcus spp.). Of the highly efficacious and safe medications that eliminate gastrointestinal helminths, commercially available in Greece are benzimidazoles, macrocyclic lactones, tetrahydropyrimidines and isokinolones. Since puppies, kittens, pregnant and nursing animals have a greater risk to acquire gastrointestinal parasites, more intensive anthelmintic schedules are usually instituted. In the less than 6-month old domestic carnivores, deworming should begin at the age of 2-3 weeks and proceed at biweekly intervals through the 12th week, followed thereafter by monthly administrations of the anthelmintics up to the age of 6 months. Nursing bitches and queens should be treated along with their offspring, since they often develop patent infections at that period of time. In animals older than 6 months, faecal examinations should be performed two to four times yearly, followed by the appropriate parasiticidal medication. In dogs which regularly receive heartworm preventatives, deworming schedules have to be modified according to their anthelmintic spectrum.

Abstract:

Abstract We predicted that haemophilia would create a prohaemorrhagic host-parasite relationship, which would make haemophiliacs very vulnerable to haemorrhagic effects of intestinal helminths in tropical countries like Nigeria. If our prediction is correct, the frequency and risks of gastrointestinal haemorrhage and iron deficiency will be higher among haemophiliacs infected by helminths in comparison with uninfected haemophiliacs. Frequency of gastrointestinal haemorrhages and iron deficiency among haemophiliacs with and without intestinal helminth infections were retrospectively obtained and analysed, and their relative risk determined by regression analysis. Haemophiliacs with intestinal helminths had significantly higher frequencies of gastrointestinal haemorrhage (73.3% vs. 18.5%, p<0.05) and iron deficiency (60% vs. 22.2%, p<0.05) in comparison with haemophiliacs without intestinal helminths. Haemophiliacs with intestinal helminths had significantly elevated relative risks (RR) of gastrointestinal haemorrhage (RR=3.4, CI95%: 2.4- 4.3, p=0.007) and iron deficiency (RR=2.5, CI95%: 1.7-3.3, p=0.009). These results showed that helminth infections were associated with increased risks of gastrointestinal haemorrhage and iron deficiency in haemophiliacs. This is thought to be due to a pro-haemorrhagic host-parasite relationship resulting from host haemostatic abnormality, coupled with the concurrent manipulation of the host haemostatic system by anticoagulants produced by some of the parasites. Haemophiliacs in tropical countries should be regularly screened and treated for intestinal helminths.

Abstract:

New scientific data on the modern epizootic situation on helminthoses of sheep of the breed Edilbayevskaya introduced on the territory of Altai region are provided. To study the contamination of animals with helminths, ovoliroscopic methods commonly used in parasitology were applied. In total 889 fecal samples received from sheep of different gender and age groups are investigated. Gelminthocomplex of animals is characterized by a variety. Tapeworms include parasites of the suborder Anoplocephalata, the family Anoplocephalidae, the genus Moniezia (M. brodeni, M. expanza) and the family Avitellinidae of the genus Thysaniezia (Thysaniezia giardi). Roundworms belong to the Strongylata suborder and are represented by 4 genera nematodes – Nematodirus, Ostertagia, Hemonchus, Oesophagostomum. The infection of lambs with helminths, including Nematodirus spp. and Moniezia spp. in 1.6–3.8 times more than at adult animals also makes respectively 48.1; 42.9 and 15.8%. A distinction of the sheep hermitage of the breed Edilbaevskaya is the low level of infection of animals with strangulates of the gastrointestinal tract, including esophagostomies (0.19%), ostertagies (1.3%), and hemones (0.2%). The dominating and subdominating components of helminthocomplex are Nematodirus spp. and Moniezia spp. For the first time the Skrjabinema ovis is registered in territory of Altai region.

Abstract:

Las parasitosis gastrointestinales son producidas por helmintos y protozoarios. Representan un peligro para las mascotas en general, por ocasionar anorexia, poca ingesta de alimentos, pérdida de sangre y proteínas plasmáticas del tracto gastrointestinal, y alterar el metabolismo proteico, con reducción de minerales, depresión de las enzimas intestinales y diarrea. Hoy en día combatir los parásitos internos en perros se realiza mediante productos químicos, de los cuales, en las localidades rurales resulta difícil conseguir estos medicamentos, convirtiéndose los perros en importantes hospedadores de agentes parasitarios de mucha importancia zoonótica en la salud pública. Se debe destacar la actividad del ajo como vermífugo, es decir, actúa contra los parásitos intestinales. Esto se debe a que su propiedad antibacteriana se mantiene activa en el tracto gastrointestinal, además, actúa como tónico digestivo, depura la sangre y facilita que el organismo depure las sustancias de desecho, también favorece la respuesta del sistema inmune y prevendrá nuevos episodios de parásitos intestinales.

Abstract:

Data on a modern epizootic situation on helminthoses of hens in the Novosibirsk region are provided in article. To study the contamination of poultry with helminths, the ovoscopic Fulleborn method, commonly accepted in parasitology, was used. In total 360 fecal samples received from the poultry contained in personal farms of citizens of Suzunsky, Toguchinsky, Cherepanovky districts of the Novosibirsk region were investigated. It is found that the parasitic complex of the gastrointestinal tract is represented by 2 classes of helminths – Nematoda and Cestoda, as well as unicellular class Sporozoa, the genus Eimeria. Nematodes include the helminths belonging to 3 families and 5 genus – Capillariidae (g. Capillaria, g. Eucoleus, g. Thominx), Ascaridiidae (g. Askaridia) and Heterakidae (g. Heterakis). Parasitosis proceed in the form of mixtinvasions. In gelminthokomplex of a poultry the dominating components are nematodes of families Capillariidae with high average infection level – 50.8%. Subdominants are Ascaris and Heterakis, their average poultry invasion is 19.2 and 23.6% respectively. The widespread distribution of pathogens nematodes is revealed, but poultry infestation with individual nematode species both in the regions and in individual settlements differs. The infestation of poultry nematodes of the families Capillariidae, Ascaridiidae and Heterakidae varies, including the level of one area. The maximum and minimum infestation of a poultry is registered by the specified helminths in Suzun, Suzunsky district and in the settlement Semenovsky of Cherepanovsky district, with infestation respectively 70,0; 46,7;40,0% and 26.9; 20.4; 21.3%. The infection of the poultry with cestodoses ranged from 0.8 to 9.4% and averaged 3.3%.

Abstract:

The purpose of the research is to establish the species composition and contamination of saigas with the main helminths, as well as to determine the effectiveness of the supramolecular complex of albendazole with polyvinylpyrrolidone at helminthoses in the conditions of the West Kazakhstan region. Materials and methods. Incomplete helminthological autopsy according to K. I. Skryabin was used to study the contamination of saigas with helminths. Supramolecular complex of albendazole with polyvinylpyrrolidone was tested on 30 saigas spontaneously infected with gastrointestinal strongylates and Moniezia spp. Animals of different groups of 10 animals each were administered orally the supramolecular complex of albendazole with polyvinylpyrrolidone at a single dose of 2.0 mg/kg of the AS compared with the base drug albendazole in a dose of 7.5 mg/kg of the AS. The control was a group of saigas that did not receive the drug. The effectiveness of the drugs was considered according to the data of coproovoscopic studies of saigas by the flotation method before and 14 days after administration. Results and discussion. The prevalence of saiga infection with Moniezia spp. in the West Kazakhstan region averaged 37%, Echinococcus sp. 25, Trychostrongilus spp. 62, Ostertagia spp. 87, Marshallagia sp. 87, Haemonchus sp. 75, Nematodirus spp. 87 and Trichocephalus spp. 25%. The 100 % efficiency of the supramolecular complex of albendazole with polyvinylpyrrolidone was obtained at strongylatosis of the gastrointestinal tract and monieziosis of saigas at a dose of 2.0 mg/kg of the AS according to the studies of fecal samples with 80–70% effectiveness of the base drug.

Abstract:

Scientific data on a modern epizootic situation on helminthoses of productive animals in Altai Republic are provided in work. Helminths applied helmintoovoskopiya techniques according to Kotelnikov-Hrenov to studying of infectiousness of animals and a helminthoovoscopy according to Berman-Orlov. More than 1.500 fecal samples from sheep, goats, marals and horses from farms of 6 administrative regions of the Republic are investigated. It is established what in the specific relation zooparazitokomplex of sheep, goats, cattle, marals and horses from various regions of Altai Republic is characterized by a variety and are provided practically by all main classes of activators – nematodes, trematodes, cestodes. Infectiousness level of animal helminths by results of an ovoskopiya and larvoskopiya fluctuated from 10.0 to 100% and from 42.8 to 100%. The characterization of the epizootic situation with the use of additional data obtained by the larvoscopic method gives a more complete picture of the structure of the helminth complex and the infection of animals with nematodes of the Strongylata suborder. This explains the fact that the average infection with helminths according to the results of larvoscopic studies is higher than with ovoscopy – due to the cumulative registration of the starch larvae of the gastrointestinal tract and respiratory system. High level of infectiousness of animals with helminths in the region emphasizes their relevance for mountain territories where the traditional systems of maintaining livestock production practice, and natural communication of animals with the environment remained. The received results of researches testify to need of constant observation of the level of an infectiousness of animals and assume realization of a system of antiparasitic actions.

Abstract The present study describes the occurrence of various gastrointestinal helminths and liver flukes in goats from post mortem examinations performed between 2010 and 2011. Forty five adult goats were euthanized necropsy examination and for identification of adult gastrointestinal helminths and liver flukes. Eleven animals (24.44 %) were found to be infected with one or more species of gastrointestinal helminth. Haemonchus contortus emerged as the most prevalent species (15.5 %), with Moniezia expansa and Fasciola gigantica also being common (11.11 % and 4.4 %, respectively). Additionally, Haemonchus longistipes, Cysticercus tenuicollis, and Paramphistomum microbothrium were present at low infection rates (2.2 %). Mixed infections were similarly most prevalent. Haemonchus longistipes; the most pathogenic Strongyle nematode of camels was reported for the first time infecting goats in Egypt. The present study indicates that abattoir surveys would reveal the prevalence of various species of problematic helminths, and thus appropriate measures can be adopted to control the respective worms.

Abstract:

AbstractThe present study was carried out to determine the prevalence of gastrointestinal helminthiasis in ruminants in an irrigated area of lower Punjab (Pakistan). For this purpose, 100 faecal samples were collected from sheep, goats, cattle and buffaloes. Parasitological procedures including direct and indirect methods (sedimentation and floatation) and coproculture were used for the identification of helminths. The overall prevalence of helminthiasis was 51% in cattle, 47% in buffaloes, 62% in sheep and 52% in goats, with nematodes being the most common helminths. The prevalence of helminths was higher in young animals compared with adults in cattle (P < 0.0001), buffaloes (P < 0.0001), sheep (P < 0.059) and goats (P = 0.010). The prevalence of different species of helminths also varied in different age groups, with Toxocara vitulorum being higher in calves than adults both in cattle (P = 0.017) and buffaloes (P < 0.0001). Sex-wise prevalence of helminths was higher in males than females for buffaloes (P < 0.0001) and sheep (P = 0.014) in contrast to cattle and goats.

Abstract:

Background. Gastrointestinal helminth parasite infection is a major influencing factor against the profitability of working equines all over the world. Methods. A cross-sectional study was conducted to determine the prevalence of gastrointestinal tract (GI) helminths and assess the associated risk factors in donkeys and horses in the Hawassa district. A total of 214 fecal samples were collected from randomly selected equines (112 donkeys and 102 horses) and examined for the presence of eggs of GI helminths using standard coprological techniques. Results. According to the current study, the prevalence of GI helminths in equine was 78.5% (168/214) and the highest prevalence was reported in donkeys 92% (103/112) as compared to horses 63% (65/102). Out of 168 positive samples, the different species of parasites were identified, namely, Strongyle species 120 (56.1%), Strongyloides westeri 76 (35.5%), Parascaris equorum 54 (25.2%), Anoplocephala perfoliata 34 (15.8%), Oxyuris equi 20 (9.3%), Fasciola hepatica 18 (8.8%), Gastrodiscus species 12 (5.6%), and Dictyocaulus arnfieldi 4 (1.8%). There was a strong association between the prevalence of GI helminths and factors such as the species of equine, body condition scores, and feed type ( p < 0.05). However, no significant association ( p > 0.05) was observed between the prevalence of GI helminths and putative risk factors such as age, sex, housing, and water source. The coproculture performed on 30 pooled fecal samples revealed that Cyathostomes species, Strongylus vulgaris, and Strongylus edentatus were the major helminth parasites of donkeys and horses. Conclusion. The frequency of gastrointestinal helminths in equine species was high, especially in donkeys. Hence, strategic deworming using broad-spectrum antihelminthic drugs and a rotational grazing program should be implemented to control and prevent the diseases.

Abstract:

Poultry industry is the promising sub-sector in livestock, which has been expanding day by day. Among the poultry species, backyard chicken is one of the appropriate incomes generating species in rural areas of Bangladesh. Parasitic infections have been considered as one of the major hindrances for backyard chicken rearing. Therefore, the present study aimed to investigate the prevalence of gastrointestinal helminths of backyard chicken in some selected areas of Bangladesh through their detailed morphological identification. A total number of 108 gastrointestinal tracts were examined for helminths from April 2018 to July 2018. The collected helminths were identified according to the keys and description of Yamaguti (1961) and Soulsby (1982). A high rate of helminth infection (100%) was observed in backyard chickens in Bangladesh. One cestode, Raillietina tetragona (67.59%); two nematodes, Ascaridia galli (43.51%) and Heterakis gallinarum (28.70%); and two trematodes, Catatropis verrucosa (21.29%) and Echinostoma revolutum (6.48%) were encountered during the study. Most of the helminths were recovered from small intestine followed by caecum. All five species of helminths were found from Dhaka and Pabna, but surprisingly no trematodes were found from Bandarban. Out of 108 chickens, 29.62% were infected with single species of helminths while the rest 70.38% harbored mixed infections. This work strongly suggests that helminths create serious problems in backyard chicken as they hamper production and therefore, appropriate control strategies are needed to design for better production.

Abstract:

AbstractAn investigation into the potential for transmission of gastrointestinal helminths from wild hogs to livestock and humans was prompted by concerns of recreational wild-hog hunting in the Caribbean region and the recent practice, by livestock farmers in Jamaica, of co-rearing wild and domesticated swine. Thirty-one wild hogs from the Hellshire Hills, a dry limestone forest in southern Jamaica, were necropsied during the period June 2004 to August 2006. Thirteen of the captured animals were male and 18 female. Four species of adult helminths were recovered from the gastrointestinal tracts of the wild hogs: Hyostrongylus rubidus (77%), Globocephalus urosubulatus (48%), Oesophagostomum dentatum (42%) and Macroacanthorhynchus hirudinaceus (77%). Two (6.2%), ten (32.2%) and 18 (58.0%) hogs harboured one, two and three species of helminths, respectively. Mean infection intensities varied from 8.1 for M. hirudinaceus, to 115.5 for O. dentatum. There was no association between any of the recovered helminths and sex of the host; however, a multivariate analysis indicated a positive association between the prevalence of G. urosubulatus and host age (odds ratio (OR) = 6.517). Domesticated hogs co-reared with wild hogs are potentially at risk of infection with all four helminths, while wild-hog hunters and pig farmers may be exposed to M. hirudinaceus.

Abstract:

A total 270 samples were collected from July 2012 to December 2012 from three upazilas (Barisal sadar, Bakergonj and Mehendigonj) of Barisal district to know the prevalence of gastrointestinal helminthes. Samples were collected in 10% neutral buffered formalin and shifted to Parasitology laboratory of the department of Pathology and Parasitology under the Animal Science and Veterinary Medicine (ANSVM) faculty of Patuakahli Science and Technology University. Samples were examined by direct smear method and simple sedimentation method of fecal sample examination technique. Among 270 samples 107 (39.6%) samples were found positive for gastrointestinal helminthes. Five types of helminthes were identified namely Fasciola gigantica (26.17%), Amphistomes (60.75%), Neoascaris vitulorum (1%), Schistosoma bovis (1%), Trichostrongylus axei (2%). The prevalence of mixed infection with Fasciola gigantica and Amphistomes was 9.34%. No cestode was found in this study. Comparative study among three different upazila shows highest prevalence in Barisal sadar (44%) and lowest in Mehendigonj (25%). Geographical location of different char island of Sadar upazila and season of sample collection may be the cause of highest prevalence of gastrointestinal helminthes in Sadar upazila of the district. Study period covered rainy season and part of winter season only. Highest parasitic ova were found in rainy season (44.32%) than winter season (29.41%). The age specific prevalence were 12.15%, 14.02%, 40.19%, 33.65% in 0-6 months, 7 months-2 years, 3 years- 6 years & 7 years - above respectively. History of administering anthelmintic (Levamisole hydrochloride) to the calf may be the cause of lowest prevalence of parasitic infection at early age in the study area. In this study, highest number (60.75%) of Amphistomes was found among positive cases. Some important Amphistomes of buffalo are Paramphistomum, Cotylophoron, Gigantocotyle, Gastrothylax etc. are difficult to differentiate through fecal sample examination. So, to understand the detail epidemiology, at least a year study using gross morphological examination with molecular characterization of helminthes is needed.DOI:http://dx.doi.org/10.3329/bjvm.v11i2.19137Bangl.J.Vet.Med.

Abstract:

Summary The aim of this study was to determine the prevalence and species composition of helminths in commensal rodents captured inside private residences in the city of Villahermosa in Tabasco, Mexico. Trapping was performed at each house for three consecutive nights from October to December 2015. Fifty commensal rodents were captured: 23 Rattus norvegicus, 16 Mus musculus and 11 Rattus rattus. Rodents were transported alive to the laboratory and held in cages until they defecated. Feces were analyzed for helminth eggs using the Sheather’s flotation technique. The overall prevalence of helminths in rodents was 60 %: R. norvegicus was more likely to be parasitized (87.0 %) than R. rattus (63.6 %) and M. musculus (18.8 %). Eggs from at least 13 species of helminths were identified: Hymenolepis diminuta, Rodentolepis nana, Moniliformis moniliformis, Heligmosomoides polygyrus, Heterakis spumosa, Mastophorus muris, Nippostrongylus brasiliensis, Strongyloides ratti, Syphacia obvelata, Syphacia muris, Toxocara sp., Trichosomoides crassicauda, and Trichuris muris. This is the first study to report the presence of H. polygyrus, S. ratti and T. crassicauda in commensal rodents in Mexico. In conclusion, our results suggest that helminths commonly infect commensal rodents in Villahermosa and therefore rodents present a health risk to inhabitants in this region.

Abstract:

<p>El presente trabajo tuvo como objetivo evaluar los parásitos gastrointestinales de equinos procedentes de ocho localidades de la Provincia de Corrientes, Argentina. Mediante técnicas de concentración se examinaron 30 muestras fecales a fin de identificar los helmintos y protozoos, así como estimar la prevalencia general y específica. Se registró una prevalencia general de P=50% y se identificaron cuatro taxones (S=4) representados por dos protozoos, Blastocystis sp (P=3,3%) y Eimeria sp (P=16,6%) y dos nematodes, Strongylus sp (P=13%) y Cyathostomun sp (P=20%). La mayoría de los reportes sobre parásitos en equinos se refieren a nematodes, por lo que el registro de protozoos es un aporte novedoso al conocimiento sobre el tema. Respecto a los nematodes identificados, han sido reportados en diferentes provincias argentinas y los grandes estróngilos representan los de menor prevalencia, mientras que los pequeños estróngilos, género Cyathostomun, los de mayor prevalencia. Los resultados obtenidos acrecientan el conocimiento sobre la temática y ponen en relieve la necesidad de implementar medidas sanitarias a fin de controlar la transmisión y mantener las cargas parasitarias por debajo de niveles que potencialmente afecten la salud, productividad o performance de los equinos.</p>

Abstract:

AbstractTransmission success for helminths with free-living stages depends on the ability of eggs and larvae to develop and survive once in the environment. While environmental conditions are often suggested to influence egg phenology and hatching rate, immunity against parasite eggs might also play a role. We examined this hypothesis using the gastrointestinal helminths Trichostrongylus retortaeformis and Graphidium strigosum, two common infections of the European rabbit. Changes in egg hatching rate and volume were examined in relation to specific antibodies in the serum and bound to eggshells, using eggs shed in host faeces over a 15-week period. Hatching rate was consistently higher for T. retortaeformis than G. strigosum and no changes were observed between weeks. Egg volume increased for G. strigosum but decreased for T. retortaeformis. We did find evidence of egg-specific antibody responses and fewer antibodies were bound to eggs of T. retortaeformis compared to G. strigosum. Little to no association was found between antibodies and hatchability, or volume, for both helminths. We suggest that host antibodies play a relatively minor role in the egg hatching rate of these gastrointestinal helminths.

Abstract:

Os cães representam os animais de estimação que mais convivem com o homem. A ligação emocional estabelecida pode trazer benefícios físicos e psicológicos, além de melhorar a integralização social de portadores de doenças imunossupressoras, idosos, crianças e pessoas com necessidades especiais. Porém, a proximidade com o cão de estimação resulta em maior exposição humana a agentes com potencial zoonótico. Este estudo teve como objetivo verificar a prevalência de ovos de helmintos e oocistos/cistos de protozoários gastrointestinais nas fezes dos cães internados no Hospital Veterinário da UnC, assim como, verificar a influência de idade, raça e sexo no percentual de animais parasitados; analisar se os parasitas encontrados possuíam potencial zoonótico; e desverminação dos animais com exames coproparasitológicos positivos. Foram coletadas amostras de 42 cães, estas foram submetidas a exames coproparasitológicos pelos métodos de sedimentação simples e Willis-Mollay. Das 42 amostras de cães analisadas, 33 apresentaram-se positivas (78,6%), e nove negativas (21,4%).O helminto encontrado com maior frequência foi Ancylostoma spp., sendo observado em 22 cães (66,6%), seguido de Trichuris vulpis e Toxocara canis que foram observados nos exames 16 (48,5%) e 11 (33,3%) animais positivos, respectivamente.

Abstract:

The objective of this study was to evaluate the performance, ingestive behavior and gastrointestinal helminths control of suckling lambs raised on pastures of Brachiaria ssp. supplemented in creep-fed and not supplemented. Thirty-one lambs being 15 lambs in the control treatment (without supplementation) and 16 lambs in the creep feeding treatment (with protein-energetic supplementation) were evaluated. Performance of lambs supplemented was superior to lambs no-supplemented. Lambs without supplemented had weaning age of 81 days and an average gain of 194 grams. Lambs supplemented showed weaning age of 58 days and average daily gain of 268 grams. eggs per gram of stool (EPG) count in the control treatment was 4553, while in the creep feeding treatment the mean was 763. The morbidity rate caused by gastrointestinal helminths in the control treatment was 6.6% and there was no morbidity due to helminths in the treatment creep feeding. The morbidity rate due to hepatogenic intoxication was 46.6% in control and 12.5% in the lambs supplemented. The ingestion of protein-energy supplementation in creep feeding promoted an increase in productive performance of lambs, as well as increased resistance and tolerance to gastrointestinal infections and decreased cases of hepatogenic intoxication by ingestion of Brachiaria spp.

Abstract:

As part of an ongoing project to investigate the epidemiology of gastrointestinal helminths of cattle in Nigeria, we carried out a systematic random sampling of cattle slaughtered in a major abattoir in Ibadan, south-western Nigeria. Using sedimentation and floatation methods, we analyzed fecal samples from 397 animals between March and May 2013. Overall, 163 (41.6%) of the animals had at least one gastrointestinal helminth egg, comprising a total of eight helminths from different genera (i.e., four nematodes, three trematodes, and one cestode), with nematode infection being the highest (71.54%). In addition, eggs of four helminths of zoonotic importance were also obtained. Among the cattle examined, the Bunaji breed was the most infected (46%; 69/150). Furthermore, female animals (OR=1.1; 95% CI: 0.60–1.84) and animals with moderate body condition (OR=1.2; 95% CI: 0.80–1.79) are more likely to be positive to helminth infection. Our findings reveal that there were helminth infections of both zoonotic and socioeconomic importance among the cattle screened. Considering the impact of the infections on animal production and public health, we advocate that effective prophylactic measures be adopted as a first step to curtail helminth infections of cattle in Nigeria.
