The purpose of the research to study the mixed course of sheep infection, caused by pathogens of fasciolosis and paraphistomatosis, in the conditions of Samarkand and Tashkent regions. Materials and methods. The research material was fallen and forcibly killed sheep from two regions of Uzbekistan, simultaneously infected by Fasciola gigantica and Paramphistomum spp. (Gastrothylax crumenifer, Calicophoron calicophorum). The animals' liver was subjected to complete helminthological dissection, followed by the presence of young immature in the parenchyma, and in the bile ducts – sexually mature fasciola. To detect pathogens of paramphistomatosis, we examined the scar and mesh, and, if necessary, the mucous membranes of the abomasum and the initial part of the small intestine. To kill the collected F. gigantica and complete bleeding with a Paramphistomum spp., they were kept in water for one and three to four days, respectively. After they took their natural form, their type, age and number were determined, and then fixed in Barbagallo fluid. If necessary, coprological studies of sheep and malacological studies of biotopes of freshwater mollusks, intermediate hosts of the studied trematodes, were carried out. Results and discussion. In recent years, cases of a mixed course in sheep fasciolosis (F. gigantica) and paramphistomatosis in farms of Uzbekistan have become more frequent. When opening the liver of the fallen sheep, up to 278 specimens were found immature F. gigantica and up to 3994 sp. G. crumenifer. In some farms, the death of individual owners' sheep from calicophorosis caused by C. calicophorum was observed with an intensity of infection of 592 sp. of C. calicophorum.

The purpose of this study was to comparative histomorphological investigation of the non affected and affected bile duct and gall bladder by fascioliasis in Black Bengal goat. The average weight of affected gall bladder was 26.10±0.70 gm which was significantly (p<0.001) higher than non affected gall bladder (19.40±0.96 gm). The average length and girth of affected gall bladder were 10.30±0.37 cm and 8.24±0.30 cm, respectively which were also significantly (p<0.001) higher than the length (6.10±0.30 cm) and Girth (5.85±0.25 cm) of non-affected gall bladder of Black Bengal Goat. The gross changes in acute form, thickening of the bile ducts and fibrosis in a portal area due to chronic fascioliasis was found in case of affected bile duct but were not found in case of non affected liver. A brownish exudates and a number of mature Fasciola gigantica were found in the lumen. The adult Fasciola gigantica was noticed in cross section in the lumen of the thickened bile ducts. Acute pathological lesions could only be produced by developing flukes prior to their entry to the bile ducts. Microscopically the epithelial layer of the bile ducts were seen to the partially disintegrated, but simultaneous proliferation of epithelial cells occurred. Thickening of the bile ducts was the result of connective tissue proliferation. Deposition of bile pigment in the tissue space and bile duct in some parts showed periductal cellular infiltrations, mainly neutrophiles, lymphocyte and eosinophiles. No calcification in the wall of the bile ducts in chronic Fascioliasis in goat could be seen in this study. The gall bladder was very dark usually contained blood clots, the consistency of bile was also very dense. Microcopically hyperplasia of the tubuloalveolar glands and numerous eggs were seen in the bile of infected goat which were absence in case of non infected goat. Asian J. Med. Biol. Res.

The dynamics of infection of horses with the trematode Schistosoma turkestanicum Skrjabin, 1913 in Karakalpakstan was studied. We carried out scientific research in various regions of the Republic of Karakalpakstan in 2016–2020. When determining the infection of horses with trematodes in the districts of Karakalpakstan, we used methods of complete and incomplete helminthological dissection by K. I. Skriabin (1928). A total of 143 horses were examined by the complete dissection method. The article presents the results of studies carried out on the territory of the Republic of Karakalpakstan. Helminths were found in all 143 horses examined during the study. The trematode Schistosoma turkestanicum Skrjabin, 1913 was among the identified helminths, which is very common in this region. The parasitic worms Schistosoma turkestanicum were found to belong to the Plathelminthes type, the Trematoda class. The study results indicate that the simultaneous presence of mixed (associative) invasions by trematodes was observed in horses. It was established that trematodes found in horses parasitize on blood vessels of the bile ducts, gallbladder, liver and intestinal mesentery. The prevalence of the trematode Schistosoma turkestanicum in horses was 18.8%, and the intensity of invasion was 3876–12538 specimens. The trematode Schistosoma turkestanicum, depending on the development cycle, develops in the presence of an intermediate host. Freshwater mollusks Lymnaea auricularia, belonging to the family Lymnaeidae perform the function of an intermediate host.

An investigation was carried out on incidence and pathology of fascioliasis in deer of Chittagong Zoo and some houses of Chittagong city during the period from January 2001 to June 2004. A total of 57 domesticated deer of various types were examined to diagnose the fascioliasis in Chittagong zoo and some house deer of Chittagong city. By faecal examination out of 44 cases 34 (77.3%) were positive for fascioliasis, of which, 15 (34.1%) cases were recorded in Chittra deer, 12 (27.3%) in Maya deer, 05 (11.4%) in Shambar deer and 02 (4.5%) in Nathrini deer. In post mortem examination, fascioliasis found in 13 (100%) cases, of which, 08 (61.5%) from Chittra deer and 05 (38.5%) from Maya deer. The overall incidence of fascioliasis in deer was 82.5%. In relation to sex the fasciolasis was significantly (p < 0.05) higher in female (82.6%) than male (71.4%) deer. The incidence of fascioliasis in various types of deer in relation to age was significantly (p < 0.05) higher in age group of above 2 years old than in age group below 2 years old. The gross examination revealed enlarged livers with round edges and thickened capsule with numerous haemorrhagic spots on the parietal surface (subacute form). In chronic form, the livers were cirrhotic and reduced in size. The affected intra-hepatic bile ducts were protruded and were engorged with flukes. Microscopically the migratory tracts were represented by the presence of haemorrhagic, oedema and infiltration with numerous eosinophils mixed with few lymphocytes. The wall of the bile ducts was thickened with fibrous tissue proliferation and the lining epithelium showed hyperplastic changes.

Liver fluke infections is an important parasitic disease that common attack cattle, buffalo and others ruminant. The disease in the tropics is caused by Fasciola gigantica trematodes. Fasciolosis found in Bali cattle besides causing high economic loss also has the opportunity infect humans. This study aims to determine the pathology changes of Bali cattle hepatobiliary system infected by F. gigantica. In January 2019 were examined a hundred of liver tissue Bali cattle. Based on the sex as many as 75 bali cattle are cows and 25 are bulls. On macroscopic examination was found fifteen bali cattles in gallbladder containing of F. gigantica. In positive Fasciolosis the surface of liver look uneven with enlargement of lymph nodes. The tissue of Bali cattle liver infected with F. gigantica is cut into 1x1x1 cm and put in a pot that has been filled with 10% neutral buffered formaline. The fixed tissue then processed in a tissue processor and stained with hematoxylin-eosin (HE). Microscopic examination was found bile ducts proliferation and blocked of the lumen accompanied by cholangio cirrhosis. Found longitudinal pieces of Fasciola gigantica liver fluke surrounded by fibrous connective tissue and multifocal coagulative necrosis with fibroblast proliferation. In some location the infiltration of neutrophil cells around the bile ducts can also be seen. Congestion, bleeding, and neutrophil infiltration are also seen in areas of necrosis. In the bile duct wall bleeding, adenomatus hyperplasia, infiltration of mononuclear cells with mild intensity and foci of calcification are found. It can be concluded that there was a change with severe intensity accompanied by chronic inflammation in the hepatobiliary system of Bali cattle with Fasciolosis.

Passive Experiment

Reindeer, in contrary to the notion of him as a ruminant animal, moreover, is able to develop strategies against ectoparasites and has a specific eating habits, increasing its chances of helminths invasion. Thus, there are reports of the reindeer eating snow soaked in human urine, brackish soil, horns of both reindeer and elks, chicks, bird eggs and excrement, as well as lemmings. Using the method of a passive experiment (observation), reindeer have been investigated in a recreational farm in the Leningrad Region (60°8′32′′N, 30°19′35′′E60.142207, 30.326466) starting from February 2018. The animals of the parent flock were brought there from the Murmansk region, and in May-June 2018 females calved. Animals are kept in a fenced area in conditions close to natural. During the growing season, they eat grass (with the addition of concentrates), in the winter they are fed with lichen. Fresh water is always available in drinkers. Photo registration of animals was carried out using a 5D Mark II (Canon) SLR camera and Xperia XA2 smartphone (SONY) camera. In addition to typical ruminant eating behavior (grazing, rumination), synchronized drinking and urination/defecation were recorded. This illustrates the route of invasion of reindeer with elafostrongylosis (previously diagnosed in these animals) – namely, through the absorption of freshwater mollusks, which, along with land gastropods, are intermediate hosts of Elaphostrongulys rangiferi. Thus, it was discovered that reindeer not only tend to avoid water consumption from reservoirs polluted with feces and urine in the presence of an alternative, but also intentionally prefer this method to compensate for the loss of minerals.

Pathology anatomy changes in liver and bile duct of Aceh cattle infected with fasciola giganticABSTRACT. This study was conducted in Banda Aceh Municipality, Aceh Province to report the pathological changes in liver of Aceh cattle infected with Fasciola gigantica. In this study, livers of male aceh cattles were collected from slaughter area when Qurban in Idul Adha during two years (2011 to 2012). A total of 15 aceh cattle livers were examined. Establishment of F. gigantica were observed, and pathological changes of liver were identified. The result showed that out of 15 male Aceh cattle livers 6 (40%) were found infected with F. gigantica. The common pathological changes found in this study were the hepatic damage, and the bile ducts were changes in size and shape with the dilated lumen. The bile ducts were found filled with blackish brown exudate, which contained adult F. gigantica. In conclusion, fascioliasis is greatly responsible for hepatic damage, and currently expanding as an important veterinary public health problem.

Fascioliasis is one of the most common neglected zoonotic disease caused by Fasciola species. The current study was conducted during January to December 2019,in which five districts were selected in various parts of Duhok governorates which differ in their environmental and geographical conditions they included: Duhok city, Zakho, Shelidiza, Aqrah and Bardarash. Each slaughter house was visited once monthly to determine the rate of fascioliasis among domestic animals; cattle, sheep and goats. The infected livers were examined grossly and the bile duct and gall bladder were inspected for the presence of Fasciola species, the work was performed in Parasitology Laboratory, Biology Dept., Faculty of Science, Zakho University. Fascioliasis was diagnosed in 2.0% (195/9757) of total slaughtered livestock, with the highest rate of infection in cattle which was 3.27% (66/2021), followed by sheep 1.76% (122/6932) and the lowest in goats 0.87% (7/804). Slightly higher prevalence rate from positive cases was found in local livestock compared to imported one (2.10% versus 1.88%). According to gender, males showed higher prevalence than females (2.08% versus 1.08%). Regarding Fasciola species, among sheep and goats; the prevalence of F. hepatica was higher than Fasciola gigantica. While among cattle, F. gigantica was the most common species. With respect to parasite burden, the heaviest burden was recorded in 38.46% (20-100 flukes/liver) of slaughtered livestock with the heaviest being in sheep (55.74%), followed by goats (71.43%) while lightest burden was recorded in cattle in 62.12% (1-10 flukes/liver). Most of the liver flukes were recovered from the bile ducts (67.69 %), followed by gall bladder (21.54%) and the least (10.77%) from both the bile ducts and gall bladder.

AbstractSpecies composition of intermediate hosts of Elaphostrongylus cervi — terrestrial snails, prevalence and intensity of their infection in natural invasions have been determined. The intermediate hosts of E. cervi are Succinea putris, Bradybena fruticum, Perforatella bidentata and Zonitoides nitidus. From June to August the percentage of snails S. putris infected with E. cervi larvae has been on constant level and in September and October decreased. Snails B. fruticum the highest prevalence of invasion showed on July and later it successively lowered. In the case of P. bidentata prevalence of E. cervi infection was the lowest in August, and than raised up to the highest value in October. For the first time the highest extensiveness of spontaneous infection has been found in P. bidentata. Till now as the most infected species of snail always has been noted S. putris. The highest intensity of infection — 242 larvae was found in B. fruticum, and little lower 73- 202 in S. putris. In two other species intensiveness ranged from 1 to 23 larvae. The most important role in spreading of E. cervi in Białowieża Forest fulfil S. putris and B. fruticum because of their high number in environment and P. bidens because of the highest intensiveness of infection.
