serodiagnosis of fascioliasis in buffaloes by immunoprecipitation using adult fasciola gigantica antigens.partial purification of a saline extract of adult fasciola gigantica by chromatography on sephadex g200 gave four peaks, of which only the first two contained material which gave a precipitation reaction with sera from infected buffaloes. none of these gave false reactions with sera from uninfected animals but even the first and most sensitive fraction only reacted with 57.5 per cent of sera from animals known to be infected with moderate numbers of f gigantica.19873547527
hepatic fascioliasis in the abattoirs of basrah.hepatic fascioliasis due to fasciola gigantica among slaughtered animals was studied at the basrah abattoirs from october 1984 to september 1985. the infection rates were 4.8, 3.3, 0.72 and 0.13% for buffaloes, cattle, sheep and goats respectively. the approximate annual loss due to condemnation of infected livers is estimated as 29,855 iraqi dinars.19873446027
studies on the energy reserve of fasciola gigantica (cobb.) from nigerian zebu cattle. ii. the fatty acid composition.the fatty acids were studied of the total lipid extracts of mature liver flukes fasciola gigantica from the bile ducts of nigerian zebu cattle. the high content of saturated fatty acids, which amounted to more than 54% of the total fatty acids, conferred a high level of saturation on these parasites. this was brought about by a general increase in the values of palmitic acid. the results are discussed in connection with the parasite-host relationship.19873426530
protective effect of irradiated metacercariae of fasciola gigantica and irradiated cercariae of schistosoma bovis against fascioliasis in goats.sensitisation of goats for eight weeks with metacercariae of fasciola gigantica gamma-irradiated at 3 kr resulted in significant resistance to an homologous challenge with normal metacercariae. however, serum sorbitol dehydrogenase assay suggested that, whereas little damage was produced by immunising infections, considerable hepatic damage was caused by flukes remaining from challenge infections. on the other hand sensitisation with cercariae of schistosoma bovis gamma-irradiated at 3 kr did no ...19873424453
liver fluke infections of cattle in mali. an abattoir survey on prevalence and geographic distribution.six hundred and ninety two cattle, slaughtered in various abattoirs in mali between august 1983 and november 1984 were examined for evidence of fasciola gigantica and dicrocoelium hospes infections. a great variation in geographic prevalence was observed. sufficient knowledge was acquired to demonstrate both the importance of fascioliasis in some areas and also the high prevalence of d. hospes in other areas. we suggest that the difference in prevalence from one geographic area to another is inf ...19883400112

problem of fascioliasis in animal husbandry in of the most important parasitic diseases in adult cattle and buffalo in thailand is fascioliasis, caused mainly by fasciola gigantica. the economic loss from fascioliasis in cattle and buffalo throughout thailand has been assessed at not less than 100 million baht. recent investigations have been shown that the average prevalence of f. gigantica in cattle and buffalo in thailand was 11.8%. however, the prevalence varies considerably between villages, ranging from 0 to 85%. the prevalence is ...19911822925
partial purification and characterisation of the proteolytic enzymes of fasciola gigantica adult worms.the proteases of adult fasciola gigantica whole worm were analysed by preparative isoelectric focusing and by gelatin-substrate gel electrophoresis at acidic and neutral ph (4.5 and 7.0). at least 15 bands of proteases were observed. these proteases had molecular weights ranging from 26 to 193 kda and isoelectric points of 4.92-7.63. protease-rich fractions were subsequently separated from whole worm preparation of the parasite by filtration in sephacryl s-200. the proteases were able to digest ...19911788929
comparative pathological study of hepatic changes induced by fasciola gigantica and gigantocotyle explanatum in javanese thin-tailed sheep.pathological changes in the liver induced by fasciola gigantica and gigantocotyle explanatum were readily distinguishable from each other. lesions associated with the migration of immature flukes through the parenchyma were a prominent feature of infection with fasciola gigantica, whereas lesions induced by gigantocotyle explanatum were confined to the large bile ducts. the size of the hepatic lesions increased during the course of infection with fasciola gigantica and was associated with the fo ...19911779036
susceptibility to homologous reinfection with fasciola gigantica in goats.goats previously infected with 100 viable fasciola gigantica metacercariae and treated with rafoxanide (ranide, 7.5 mg/kg) at week 4 were not protected against subsequent homologous challenge with 250 metacercariae administered two weeks later. reinfection resulted in more severe hepatic lesions and a higher percentage of flukes recovered as compared with primarily infected controls. however, the size of flukes originating from the second (challenge) infection was considerably reduced. the plasm ...19911775694
