| dc.description.abstract | This study was conducted in Sylhet district, Bangladesh to determine the prevalence of Fascioliasis in goats of different age groups, sex and in seasons. Prevalence of Fascioliasts among ruminants in Bangladesh is rampent and the economic loss from this disease is considerably high. In this study, livers of male and female gouts of different age groups were collected randomly from slaughter house during a period from October, 2007 to September, 2008. Out of 318 livers examined of which 66 (20.75% were found to contain Fasciola gigantica. The prevalence rate was 20.75%. The prevalence was significantly (P<0.05) higher during rainy season (26.16%) followed by dry season (17.14). Fascioliasis was observed significantly (P<0.001) higher in older (58.33%) animals at one year of age and the female (36.79%) were affected more (P-0.001) with the disease than males (12.73%). Acute infection of Fascioliasts causes severe inflammation in the liver and death occurs accompanied by passage of blood stained discharge from the anus and nostril. In clinical cases dullness, weakness, hes of appetite and abdominal pain may be observed. Chronic Fascioliasis characterized by progressive fibrosis of the liver. The bile ducts frequently show hyperplasia and, later loss of their epithelium; their walls are thickened and may eventually become calcified (pipestem liver') Affected animals also tend to show progressive anensita, low plasma albumin submandibular edema (bottle jaw), depression and weight loss. Direct lonnes due to Fascioliasis are host mortality and liver condemnations whereas indirect losses may occur in a form of losses in body weight and decreased weight of kids from infected goats Fascioliasis has recently been shown to be an important public health problem with human cases reported from countries in five continents, the level of endemcity ranging from hypo to hyper codemic. Despite the wide prevalence of the malady and huge loss sustained from it, no epidemiological study on the disease in gouts have so far been undertaken in Sylhet district of this country. Considering this fact, the present study was designed to determine the prevalence of Fillipinen praty Jarmy October, 2007 to September, 200% at Sylhet, Bangladesh | en_US |
