Abstract:
Introduction. The class Cestoda is divided into two subclasses: the Cestodaria — unsegmented tapeworms, and the Eucestoda — true cestodes. The representatives of the orders Pseudophyllidea and Cyclophyllidae, which are part of the subclass of true cestodes parasitize in carnivorous mammals. At the same time, only representatives of the latter order parasitize in chiropterans. Data on the species composition and distribution of cestodes in the Rostov region have not been published yet. The list of bat species living in the Rostov region have been compiled previously. In this article, the authors study the cestode fauna parasitizing in chiropterans in the region under study. This review aims to analyse the current state of knowledge about the species composition of helminths parasitizing in bats in the Rostov region.Materials and Methods. The research materials have been obtained from the libraries and open access resources: PubMed (pubmed.ncbi.nlm.nih.gov), CyberLeninka (cyberleninka.ru), Google Scholar (scholar.google.com), BHL (www.biodiversitylibrary.org ), JSTOR (www.jstor.org), etc. Some data has been provided by the colleagues. Results. 17 species of cestodes of 4 genera, 1 family and 1 order can be found in 15 species of bats living in the Rostov region. Among them dominate the species of the genus Vampirolepis (11 species).Discussion and Conclusion. The results of the review carried out showed that maximum diversity of cestodes was found in one species of bats — the serotine bat (10 species). The smallest number of cestode species (1 per each) was found in the giant and lesser noctules. None of the cestode species found in bats in the Rostov region were recorded in companion animals or humans. However, some cestode species of the Hymenolepididae family, common in rodents, can infect the humans.

Abstract:
An ecological and physiological study of Common Eider (Somateria mollissima) nesting on the coast of Eastern Murman was carried out. The species composition of helminthofauna of birds and the quantitative parameters of the infection were studied. It is established that trematodes of the genus Microphallus, three species of cestodes - Lateriporus teres (Cestoda: Dilepididae), Fimbriarioides intermedia (Cestoda: Hymenolepididae), Microsomacanthus diorchis (Cestoda: Hymenolepididae) and one species of acanthocephalan - Polymorphus phippsi (Palaeacanthocephala: Polymorphidae) parasitized in the small intestine of Common Eider. It is shown that the activity of proteases decreased at the locations of F. intermedia and M. diorchis in the intestines of birds, with infestation with the acanthocephalan P. phippsi, on the contrary, increased. The activity of glycosides in the intestinal mucosa was reduced in comparison with the control values by infection cestodes M. diorchis. There was an increase in the values of hematological indices in infected individuals relative to the control parameters.

Abstract:
Tapeworms of domestic ducks (Anas platyrhynchos dom.) causing helminthiasis and serious damage to the hosts, cause economic damage in the poultry industry. Helminthological research devoted to the study of the parasite fauna, including tapeworms of domestic ducks, has been carried out in many countries. But there is no review information on the study of the helminth fauna of domestic ducks. We take our own materials and literature data and summarise the information on cestode parasites of Anas platyrhynchos dom., which have been recorded in the world until 2020. Each species is provided with the following data: scientific name, authority and year, intermediate and auxiliary hosts, habitat in the host body, collecting localities and geographic distribution, prevalence and intensity of infection and literature sources. Based on our own research and analysis of literature data, it was revealed that hitherto there are 419 species of helminths (Trematoda – 213, Cestoda – 89, Nematoda – 79, Acanthocephala – 11) recorded parasitising domestic ducks. The tapeworms found in Azerbaijan belong to four families (Dilepididae – 3, Hymenolepididae – 68, Davaineidae – 13, Diphyllobothriidae – 5). In Azerbaijan, 11 out of 89 species of helminths have been found in domestic ducks. Six of them were also noted in the course of our helminthological studies. The cestoda Diorchis inflata was recorded the first time in domestic ducks in Azerbaijan. Most species of cestodes were found in the north-eastern regions of Azerbaijan (Shabran – 11 species, Khachmaz – 6 species) and the southern region (Astara – 4 species). All of these areas are located on the shores of the Caspian Sea and are located on the annual migration route of wild birds involved in the spread of cestodes, which are considered biohelminths. Six species (Drepanidotaenia lanceolata, Hymenolepis apodemi, Hymenolepis diminuta, Ligula interrupta, Ligula intestinalis, Schistocephalus solidus) of cestodes parasitize both birds and mammals (D. lanceolata, H. diminuta in humans).

Abstract:
Objective of research: To study the activities and properties of nucleoside- diphosphatase (NDPase) in cestode Bothriocephalus scorpii. Materials and methods: Cestodes were homogenized with 10 vol. of extraction medium. NDPase was detected in mitochondria and microsomes with substrates (IDP, GDP, UDP). Inorganic phosphorus was determined by the method of Kochetov (1980). The effects of 10 anthelmintic drugs on the activity of NDPase were studied. Results and discussion: It was found that the mitochondrial and microsomal fractions of cestodes B. scorpii have nucleoside diphosphatase activity. The activity of nucleoside diphosphatase depends on substrates and Mg2+ ions. The impact of various effectors and ions (Ca2+, Mn2+, Zn2+) on enzyme activity was determined. Effects of 10 anthelmintic drugs on activity of nucleoside diphosphatase were studied. The anthelmintics Bitionol and Trichlorophen have been proved effective.

Abstract:
The aim of this study was to determine the distribution of parasites of the class Cestoda in farmed common carp from the cyprinid aquaculture facilities in Macedonia. The representatives of the class Cestoda occur most often during the winter (in 3.47% of examined fish), followed by spring (1.80%) and autumn (1.73%). They haven`t been identified during the summer. 20 fish out of 958 totally examined were infected with cestodes, with a mean intensity of 6.40, and a prevalence of 1.76%. In this study, the following parasite species were established: Caryophyllaeus fimbriceps, Bothriocephalus opsariichthydis and Ligula intestinalis (plerocercoid). Based on the total number of fish examined from cyprinid aquaculture facilities in Macedonia, the highest prevalence from the class Cestoda is determined by Bothriocephalus opsariichthydis (1.04%), followed by Caryophyllaeus fimbriceps and Ligula intestinalis with 0.55% each. The highest mean intensity with parasites of the class Cestoda is determined by Caryophyllaeus fimbriceps (9.40), followed by Bothriocephalus opsariichthydis (6.30) and Ligula intestinalis (3.60). The records of Caryophyllaeus fimbriceps in farmed common carp in the present study are considered as the first records for Macedonian aquaculture.

Abstract:
The brine shrimp genusArtemiaLeach (Crustacea, Branchiopoda), a keystone group in hipersaline wetlands all over the world, offers an excellent model to study species interactions (parasitism) and to explore “hidden fauna” (avian endoparasites). The present study is the first report on the parasite infection of the South American speciesArtemia persimilisfrom the Southern Chilean Patagonia (50°S–53°S). Samples were collected in Los Cisnes and Amarga lagoons, the two most austral populations of this crustacean described to date, during two seasons (spring and autumn). A total of 98 larvae of cestodes of the family Hymenolepididae (Cestoda, Cyclophyllidea) were found and identified as belonging to the following taxa:Confluaria podicipina(adult parasitic in grebes),Flamingolepissp. (a cestode parasite of flamingos),Fimbriarioides(?) sp. (adults of the species of this genus infect waterfowl and shorebirds) andWardiumsp. (definitive host unknown, most probably charadriiform birds). This is a new geographical record ofC. podicipinaand the genusFimbriarioidesfor the Neotropical Region, the latter being the most widely distributed species at both localities and seasons surveyed, and the only species recorded in autumn (April). Cestode community composition in Los Cisnes population was characterised by dominance ofFlamingolepissp., representing more than 65% of the total cestode species recorded, whereas in the Amarga population the most abundant parasite (>83%) wasFimbriarioides(?) sp. Significant seasonal variations were detected in Los Cisnes lagoon forFlamingolepissp. andC. podicipina, with exclusive presence of them in spring (November). Besides providing novel information on cestodes infection inA. persimilis,this study provides new data on the life cycle of cestodes of Neotropical aquatic birds such as South American flamingos and grebes. Our finding expands the knowledge on the biodiversity and population dynamics of extreme and unique environments from high latitudes (Patagonia) and makes evident the need of further taxonomical and ecological studies for better understanding the life cycles of avian helminth parasites in the Neotropics and the role of aquatic invertebrates in them.

Abstract:
Helminths of 12 fish species collected near the South Orkney Islands, West Antarctica were studied. In the whole sample of 115 fish specimens, we identified one species of Monogenea, 5 species of Trematoda, 4 species of Cestoda, 5 species of Nematoda, and 7 species of Acanthocephala. All cestode species, 3 species of nematodes, and 5 species of acanthocephalans were represented only by larval stages; fish are definitive hosts for the remaining 10 helminth species. Details of composition and structure of helminth communities were studied in 3 fish species: Chaenocephalus aceratus (Lönnberg, 1906), Champsocephalus gunnari Lönnberg, 1905, and Pseudochaenichthys georgianus Norman, 1937, each represented by more than 20 specimens in a sample. In these hosts, 19, 8, and 16 helminth species were found, correspondingly. In the helminth communities of C. aceratus and P. georgianus, the highest values of the infection prevalence and abundance were recorded for larval cestodes (Diphyllobothrium sp., Tetrabothriidea), nematodes (Pseudoterranova sp., Contracaecum sp.), acanthocephalans (Corynosoma spp.), as well as adults of the trematode Neolebouria georgiensis Gibson, 1976. The same trematode species and larval cestodes predominated in the helminth community of C. gunnari. All recorded species of parasites are generalists, each known from a range of fish hosts in Antarctica.

Abstract:
In many countries, poultry (including Anser anser dom.) play an important role in meeting population needs for meet. One of the factors that affect directly the meat quality and the industrial products obtained from domestic waterfowl are helminths, which cause diseases in their hosts. Helminthological research of the helminth fauna of domestic geese has been carried out in many countries, including Azerbaijan. Nevertherless, there is no general survey or species list of the world fauna of the domestic goose helminths. Tapeworms (Class: Cestoda) also parasitize the geese, causing them serious harm. Taking into account the relevance of the topic, we set the task to determine and systematize the species composition of tapeworms parasitizing the domestic goose (A. anser dom.) with the use of extensive literature data and our personal material. The species list is arranged in alphabetical order, families, genera and species of cestodes follow the nomenclature and classification by Khalil et al. (1994) and Olson et al. (2001), with updates by Kuchta et al. (2008) and Caira et al. (2014). We also took into account the classification adopted from the database of Fauna Europaea. Each species is provided with the following data: scientific name, author and year of description, synonyms, final, intermediate and auxiliary hosts, habitat in the bird body, collecting localities, geographic distribution, prevalence (PI) and intensity (II) of infection, and literature sources. An analysis of the worldwide literature and our personal data has established that 147 helminth species (Trematoda – 64 species, Cestoda – 33, Nematoda – 46, Acanthocephala – 4) are hitherto known from the domestic goose. The 33 tapeworm species of this list belong to five families (Dilepididae – 1 species, Hymenolepididae – 27, Mesocestoididae – 1, Paruterinidae – 1, and Diphyllobothriidae – 3). In Azerbaijan, 11 cestod species were found in the domestic goose. Six of them (Diorchis inflata, Drepanidotaenia lanceolata, D. przewalskii, Fimbriaria fasciolaris, Tschertkovilepis setigera, Ligula intestinalis) were registered in the course of our helminthological studies. The cestodes D. inflata and L. intestinalis were recorded in domestic geese in Azerbaijan for the first time. Five helminth species (Dilepis undula, Drepanidotaenia lanceolata, Ligula interrupta, L. intestinalis, Schistocephalus solidus) parasitize both birds and mammals (D. lanceolata in humans). Of these, two species (D. lanceolata and L. intestinalis) were found in Azerbaijan.

Abstract:
O Filo Platyhelminthes inclui todos os vermes achatados e contém quatro Classes: Turbellaria, Menogenea, Trematoda e Cestoda. A primeira é composta predominantemente por organismos de vida livre, a segunda por ectoparasitas e as Classes Trematoda e Cestoda são compostas por endoparasitas obrigatórios. Os cestódeos são agentes etiológicos de algumas das principais doenças de seres humanos e animais domésticos, apresentado complexos ciclos de vida que abrangem, pelo menos, dois hospedeiros. Entre as suas adaptações ao parasitismo, alguns cestódeos da Subclasse Eucestoda apresentam repetição seriada dos órgãos reprodutivos (metamerismo) e a segmentação externa destes (proglotização), apresentando, assim, uma enorme capacidade reprodutiva. Porém, pouco se sabe dos aspectos moleculares envolvidos na biologia do desenvolvimento desta estrutura corporal. O presente trabalho descreve as relações evolutivas entre organismos endoparasitas do Filo Platyhelminthes através de análise filogenômica, assim como a interrelação dos platelmintos com demais representantes do Superfilo Lophotrochozoa. Por meio da comparação de dados genômicos, transcritômicos e inferência funcional, este trabalho descreve um total de 34 proteínas associadas ao processo de proglotização, conservadas em platelmintos da Classe Cestoda. Entre estas proteínas, 12 estão relacionadas a processos de desenvolvimento, incluindo vias bem conhecidas como as vias de sinalização da wnt e do TGF-β/BMP. Adicionalmente, a identificação de 22 proteínas hipotéticas conservadas e a descrição de seus domínios, adiciona importantes alvos para o estudo da evolução deste processo de desenvolvimento na Classe Cestoda.
The Phylum Platyhelminthes includes all flatworms and contains four classes: Turbellaria, Menogenea, Trematoda, and Cestoda. The first one is predominantly composed of free-living organisms, the second by ectoparasites and the Trematoda and Cestoda Classes are composed of obligatory endoparasites. The cestodes are etiologic agents of some of the major diseases of humans and domestic animals, and present complex life cycles that include at least two hosts. Among its adaptations to parasitism, some cestodes of Eucestoda Subclass have serial repetition of their reproductive organs (metamerism) and external segmentation of these (proglottisation), thus presenting an enormous reproductive capacity. However, little is known about the molecular aspects involved in the biology of development of this kind of body structure. This work describes the evolutionary relationships among endoparasite organisms from Phylum Platyhelminthes through phylogenomic analysis, as well as the interrelationship of flatworms with other species representing the Superphylum Lophotrochozoa. Through genomic data comparison, transcriptomic analysis and functional inference, this work describes a set of 34 proteins associated with the proglottisation process, preserved in flatworms Class Cestoda. Among these proteins, 12 are related to developmental processes, including well described pathways as the Wnt and TGF-β / BMP signaling pathways. Additionally, the identification of 22 conserved hypothetical proteins and the description of its domains adds important targets for the study of the proglottisation evolution in the Class Cestoda.

Abstract:
Gastrointestinal (GI) helminths pose a significant threat to the livestock industry and are a recognized cause of global morbidity in humans. Control relies principally on chemotherapy but in the case of nematodes is rapidly losing efficacy through widespread development and spread of resistance to conventional anthelmintics and hence the urgent need for novel classes of anthelmintics. Cysteine proteinases (CPs) from papaya latex have been shown to be effective against three murine nematodes Heligmosomoides bakeri, Protospirura muricola and Trichuris muris in vitro and in vivo and against the economically important nematode parasite of sheep Haemonchus contortus. Preliminary evidence suggests an even broader spectrum of activity with efficacy against the canine hookworm Ancylostoma ceylanicum, juvenile stages of parasitic plant nematodes of the genera Meloidogyne and Globodera and a murine cestode Hymenolepis microstoma in vitro. This project focused on tapeworms. Using 2 different rodent cestodes Hymenolepis diminuta and Hymenolepis microstoma and 1 equine cestode Anoplocephala perfoliata I have been able to show that CPs do indeed affect cestodes whether young newly hatched scoleces in vitro (by causing a significant reduction in motility leading to death of the worms) or mature adult worms in vitro (by causing a significant reduction in motility leading to death of the worms) and in vivo (resulting in a significant, but relatively small, reduction in worm burden and biomass), despite no effects on worm fecundity. Although only minimally efficacious against Hymenolepis microstoma and moderately efficacious against Hymenolepis diminuta in vivo, efficacy was enhanced by the synergistic effects of the immune system demonstrated against Hymenolepis diminuta in the non-permissive host. The results offer the possibility that with further refinement, CPs may be developed into broad spectrum anthelmintics that in addition to their marked effects on nematodes also remove any concurrently residing tapeworms.

A presença de microssatélites no genoma de Echinococcus granulosus foi verificada utilizando-se oito oligonucleotídeos com repetições como sondas (GT15, CT15, AT15, CG15, CAT10, CAA10, CGG10 e CATA10). Experimentos de hibridização revelaram que as repetições GT, CAA, CATA e CT são as mais frequentes no genoma de E. granulosus. As sondas AT e GC não apresentaram sinais de hibridização. Seis lócus contendo repetições CA/GT, quatro lócus contendo repetições GA/CT e oito lócus contendo repetições AAC/GGT foram clonados e sequenciados. O lócus Egmsca1 foi analisado em 73 isolados do Brasil e da Argentina cujas linhagens haviam sido previamente caracterizadas e em 27 isolados provenientes da Etiópia cujas linhagens ainda não foram identificadas. Os isolados brasileiros da linhagem bovina e os isolados argentinos da linhagem do camelo apresentaram-se monomórficos e compartilharam o alelo (CA)7. Isolados argentinos das linhagens da ovelha e da ovelha da Tasmânia compartilharam dois alelos [(CA)8 e (CA)10] com os isolados brasileiros da linhagem da ovelha. O alelo (CA)11 foi encontrado somente em isolados brasileiros da linhagem da ovelha em uma baixa frequência. O alelo (CA)9 ocorreu apenas em um isolado da Etiópia. As populações brasileira e argentina da linhagem da ovelha foram testadas em relação ao equilíbrio de Hardy-Weinberg e somente a primeira estava de acordo com as expectativas. Protoescólices isolados de um único cisto hidático não apresentaram polimorfismo, validando a utilização de protoescólices de um mesmo cisto, agrupados como um isolado, em estudos populacionais. Um microssatélite contendo repetições de pentanucleotídeos, contido no complexo gênico do snRNA U1, também foi isolado. Este estudo descreve pela primeira vez o isolamento e caracterização de microssatélites em E. granulosus.

Abstract:
Over recent years it has been established that pollutants can have a significant impact on lost-parasite systems in water so much so that it has been proposed that parasite fauna may be a usefiil parameter to monitor water quality. Surprisingly, with perhaps the exception of trematodes, detailed observations on the interaction between other helminths and pollutants, such as heavy metals, are lacking. In this study eggs and coracidia of the carp tapeworm, BothriocepJialus acheilognathi were exposed to a range of cadmium concentrations (0.1-10,000μg/l). Results indicated that the egg is highly resistant to Cd pollution, hi contrast, the activity of the liberated coracidium is significantly decreased after Ih exposure to cadmium at 10 & 100μg/l.

Abstract:
The immunocytochemical study of cestode larvae, Mesocestoides vogae tetrathyridia (Cestoda, Mesocestoididae) detected serotonin-immunopositive neurons and fibers in the central and peripheral nervous system. The wholemounts were analyzed by confocal laser scanning microscopy. The size of serotonergic neurons, and the distance between the lateral nerve cords, and between the commissures were measured for the first time in the head, middle, and posterior regions of the larvae. Serotonergic nerve components of the M. vogae larvae were detected in the nerve ganglia in the head located between four suckers on the anterior part, as well as between clearly visible three pairs of lateral, dorsal, and ventral longitudinal nerve cords connected by transverse commissures. The distance between the lateral nerve cords was 130.90±33.92 µm, and between the commissures, 24.66±6.02 µm. Sizes of M. vogae’s neurons were as follows: length, 9.84±1.97 µm, and width, 7.19±1.50 µm. The largest serotonergic neurons were observed in the head region of the cestodes. The neurons in the head and middle regions of the body demonstrated the most intensive staining. The results indicate wide spreading serotonin in flatworms which is already found in the early stages of their life cycle.

Abstract:
Eight out of the eleven indigenous fish species of Prespa are endemic, i.e. they exist only in the Lake Prespa. One of these endemic fish species is Prespa bleak (Alburnus belvica). The parasitological examination from the Macedonian part of the Lake Prespa in 2023 showed that all of 14 examined specimens of Prespa bleak fishes were infested (100.0%). In our case study the presence of 8 parasite species was established: Gyrodactylus sp., Dactylogyrus alatus f. typica, Dactylogyrus fraternus, Dactylogyrus sphyrna, Posthodiplostomum cuticola (larva), Cestoda gen. sp. (larva), Raphidascaris acus (larva) and Ergasilus sieboldi. Individually, by the parasite species, the highest prevalence was with Dactylogyrus fraternus, Dactylogyrus sphyrna and Posthodiplostomum cuticola (larva) (71.43%). The lowest one was with Cestoda gen. sp. (larva) (7.14%). In our case study the parasites Gyrodactylus sp., Dactylogyrus fraternus and Cestoda gen. sp. (larva), are recorded for the first time in the ichthyoparasitofauna of Lake Prespa and Macedonia.

Abstract:
On the territory of the North-Western Caucasus from 2010 to 2022, 60 badgers from 3 landscape-geographical zones were studied by the method of complete helminthological dissection. The prevalence and intensity of invasion, abundance index and dominance index were calculated. Infection of badgers with helminths was 100%. Helminthic cenosis was represented by 20 species of parasitic worms from 4 classes Trematoda, Cestoda, Nematoda and Acanthocephala, and 16 families. The detected helminths included 6 trematode species (30.0%), 3 cestode species (15.0%), 10 nematode species (55.0%) and one species of Acanthocephala (5.0%). Nineteen helminth species were found in the plain zone, 15 species in the foothill zone, and 9 species in the mountainous zone. The dominant trematode species was Euparyphium melis (the II average 32.0 specimens; AI 9.6; DI 16.5%). Subdominant species were Alaria alata (the II average 16.4 specimens; AI 5.5; DI 9.4%) and Pharyngostomum cordatum (II average 31.5 specimens; AI 3.1; DI 5.4%). The dominant cestode species was M. lineatus (II average 11.0 specimens; AI 5.1; DI 8.8%), and subdominant species was T. crassiceps (II average 7.3 specimens; AI 2.8; DI 4.8%). The dominant nematode species was U. stenocephala (II average 37.5 specimens; AI 17.5; DI 30.1%), and subdominant species were Molineus patens (II average 24.6 specimens; AI 4.5; DI 7.8%), and Thominx aerophilus (II average 7.6 specimens; AI 2.4; DI 4.1%). Analysis of the stomach contents of the badgers showed that a significant proportion of the diet consisted of animal feed which was present in the stomach of 90.0% of the examined animals. Fragments of rodents, amphibians, reptiles, fish, insects, mollusks, and annelids were found in their stomach.

Abstract:
Bank vole (Myodes glareolus) is widely spread silvicolous species, inhabiting in woods, forest clearings, shrub vegetation, at forest edge, near ponds with abundant vegebtation. The parasite fauna is structured of 3 classes, 13 families, 14 genera and 15 species, of which 6.6% belong to class Trematoda, 46.7% to class Cestoda and 46.7% to class Nematoda. The results of the parasitological investigations show a prevalence of Plaghiorchis elegans of 13.8% and an average intensity of 3.8 ex, respectively with Mesocestoides lineatus larvae 14.0%, 1.5 ex, Paranoplocephala omphaloides - 10.3%, 2.7 ex, Rodentolipis straminea - 69.0%, 3.0 ex, Hydatigera taeniaeformis larvae - 10.3%, 1.0 ex, Catenotaenia cricetorum - 10.3%, 2.7 ex, Skrewabinotaenia lobata - 3 ex, Taenia pisiformis - 13.7%, 1.0 ex, Capillaria hepatica - 27.5% and liver infestation is about 50.0% (++), Syphacia stroma - 17.2%, 94 ex, Syphacia obvelata - 24,1%, 84,9 ex, Heligmosomoides polygirus - 10,0%, 5,3 ex, Strongyloides ratti - 6,9%, 23,3 ex, Mastophorus muris - 17,2%, 3 , 6 ex and Trichocephalus muris 17.2%, intensity 3.8 ex. The share of the Trematoda species is 6.6%, in the Cestoda class - 46.7%, and in the Nematoda class - 46.7%. The massive abundance of foxes on large land surfaces, including ecological plasticity with tendency toward synantropization, are the primary factors in the formation, maintenance and spreading of parasitosis outbreaks in natural and anthropic ecosystems. The aim of the research is to study the diversity of parasite fauna in Myodes glareolus from forest ecosystems with specifying the parasite taxonomic structure and determining the degree of infestation.

Abstract:
The importance of wetlands for humanity is very high. They provide a huge number of people in the world with their water and biological resources, determine the stability of local climatic conditions, and serve as habitats for many sedentary and migratory waterfowl and semiaquatic birds. In the reservoirs of the transboundary rivers Amudarya, Syrdarya and Zarafshan (within Uzbekistan), numerous species of wetland birds are concentrated, which are poorly studied in terms of parasitology. The paper presents some features of the helminth fauna in wetland birds of NorthWestern, Central and North-Eastern Uzbekistan. The material for this work was the collection of parasitic worms of waterfowl, marsh and semiaquatic birds caught in the water bodies of the Amudarya, Syrdarya and Zarafshan river basins (within Uzbekistan) during the hunting season (2018–2022). More than 750 birds belonging to 40 species, 26 genera, 15 families and 9 orders were collected and studied. The studied birds turned out to be infected with helminths of 4 classes, Cestoda, Trematoda, Acanthocephala and Nematoda. One hundred seventeen species were identified: 29 species belonged to the cestode class, the trematode class was represented by 67 species, the nematode class, by 27 species, and the acanthocephalan class by 4 species. Original data on the structure of the helminth fauna of 9 orders of birds were presented. Various transmission ways of helminths to the final hosts were elucidated.

Abstract:
The study of the diversity of the parasite fauna in the investigated foxes showed a high level of infestation (100%). The taxonomy of parasitofauna in foxes includes 12 parasitic invasions (Isospora canis – 14,3%, Alaria alata – 51,0%, Mesocestoides lineatus – 21,7%, Taeniidae spp – 27,0%, Syphacia obvelata – 17,0%, Strongyloides stercoralis – 13,3%, Toxocara canis – 59,0%, Toxascaris leonina – 65,5%, Ancylostoma caninum – 8,7%, Trichuris vulpis – 26,1%, Trichuris muris – 4,4%, Capilaria hepatica – 35,0%), which belong to 5 classes, 10 families, 11 genera and about 12 species. The share of species from the Sporozoa class is 8.3%, from the Trematoda class - 8.3%, from the Cestoda class - 16.7%, from the Secernentea class - 41.7% and from the Adenophorea class - 25.0%. Analyzing the parasitic species on epidemiological criterion, it was found that 10 species (83.3%) with large spread have zoonotic impact (A. alata, M. lineatus, Taenia spp., S. obvelata, S. ratti, T. canis, T. leonina, A. caninum, C. hepatica, T. vulpis) with a major risk to public health, and the identified invasions (100%) can parasitize domestic animals, as well as game fauna.

Abstract:
One of the problems in horse breeding in the Tyumen Region is significant spread of helminthiasis. The purpose of our research was to study the species composition and symptoms of equine helminth infections on the farms in the Tyumen Region. We performed clinical examinations of the animals and coprological studies of horse feces for intestinal helminth infections. We also check the surface contents with perianal, circumanal and perineum swabbing taken with a stick and clear adhesive tape. Тhe diagnosis was confirmed by common laboratory research methods (Fülleborn’s method, helminthoscopy, G. A. Kotelnikov and V. M. Khrenov flotation method). The results of studies found that the horses had Class Nematoda helminths of the suborder Strongylata (Delafondia vulgaris, Strongylus equinus and Trichonema sp.) recorded most frequently with the prevalence of 67.20±2.07% and the infection intensity of 647.10±5.47 eggs per gram of feces; the Parascaris equorum prevalence, 48.00±1.52% with the infection intensity, 409.7±5.4 eggs/g; the Oxyuris equi prevalence, 20.2±1.16% with the infection intensity, 436.40±3.67 eggs/g; and the Strongyloides westeri prevalence, 9.4±0.53% with the infection intensity, 87.60±2.78 eggs/g. Class Cestoda helminths of the species Anoplocephalata perfoliata were found less frequently with the prevalence of 0.20±0.03% and the infection intensity of 10.30±0.74 eggs/g.

Abstract:
There are not so many comprehensive studies for helminthological contamination of urbanized environment of the northern part of Belarus with eggs of helminths of carnivores including domestic ones. The routine examination for environmental contamination by helminth eggs carried out by the Sanitary and Epidemiological Services is limited to foci of incidence in humans. This determines the need for constant monitoring of parasitic contamination of environmental objects on urbanized territories of the northern part of Belarus. The article contains data on the species diversity of helminths in domestic carnivores found in the soil of the selected area. 813 soil samples were taken and analyzed. Twelve helminth genera were identified, namely, Toxocara spp., Toxascaris spp., E. granulosus, Taenia spp., Dipylidium spp., Ancylostoma spp., Uncinaria spp., Strongyloides spp., Trichocephalus spp., Capillaria spp., Mesocestoides sp., and Alaria sp., which belong to three classes, Trematoda, Cestoda, and Nematoda. The highest prevalence in both urban and rural areas was observed for representatives of the genus Toxocara. The helminth species diversity in urban areas exceeded that in rural areas. The found species were represented by bio- and geohelminths. Eight of the species found belong to the group of zoonotic helminths: T. canis, T. leonina, D. caninum, A. caninum, U. stenocephala, T. vulpis, E. granulosus, and A. alata.

Abstract:
Northwestern Uzbekistan occupies a large area in the lower reaches of the Amu Darya. The region is distinguished by peculiar natural and climatic conditions. Most species of wild artiodactyls of the order Artiodactyla are represented here, and sheep, goats and cattle are also raised here. However, the helminth fauna of the study groups of mammals in North-Western Uzbekistan covering the territories of the Khorezm Region and the Republic of Karakalpakstan remains poorly studied to date. We have studied some features of the helminth fauna in domesticated and wild cavicornians, Bovidae Gray, 1821, of North-Western Uzbekistan. The species composition of helminths of the studied animals consisted of 26 species belonging to 3 classes, Cestoda, Trematoda and Nematoda. The helminth fauna of cavicornians turned out to be uneven. Twenty six species of parasitic worms were recorded in cattle, 23 species in sheep, 17 species in goats, 15 species in saigas, and 16 species in goitered gazelles. The total helminth infection rate was 100% in sheep, 75% in goats, 95.0% in cattle, 55.0% in saigas and 61.5% in goitered gazelle. The intensity of invasion in the studied animals ranged from single to several dozen specimens. At the same time, in most cases, mixed invasions of various combinations were detected.

Abstract:
Este trabalho tem por objetivo aplicar uma metodologia para a mensuração de efeitos distributivos relacionados à incidência de impostos indiretos sobre as despesas de consumo das famílias brasileiras. A metodologia consiste basicamente de duas etapas. Na primeira, as alíquotas efetivas dos principais impostos e contribuições que compõem a carga tributária indireta brasileira são estimadas a partir dos coeficientes técnicos da Matriz Insumo-Produto de 1996 do IBGE e dos valores arrecadados dos impostos informados nas Contas Nacionais de 2002 do IBGE. Na segunda etapa as alíquotas efetivas são aplicadas sobre as despesas com uma cesta de consumo; despesas essas informadas pelas famílias ao IBGE e que constam dos microdados da última Pesquisa de Orçamentos Familiares (1995-96). Os resultados finais consistirão portanto de estimativas do peso da carga tributária indireta incidente sobre uma cesta de consumo bastante representativa no orçamento das famílias de baixa renda. Essas estimativas serão apresentadas como proporção da renda média de cada décimo populacional (indicador de regressividade) e das despesas de consumo (alíquotas efetivas)
