Epidemiological pattern of the helminths diseases would provide a basis for evolving strategic and tactical control of different diseases. By taking into consideration these points, authors were very interested to study about the epidemiological investigation of gastro-intestinal helminths infestation of swamp buffalo in Sylhet district. Materials and Methods: The study was conducted from the period of November, 2015 to October, 2016. For the purposes, total 947 buffalos faeces were collected and examined coprologically in the laboratory, Department of Medicine, Sylhet Agricultural University, Sylhet. All the collected data were entered to MS excel sheet and analyzed by using SPSS version 13. Results: A total of seven species of gastro-intestinal parasites were identified. The prevalence of Fasciola sp., Paramphistomum sp., Neoscaris sp., Strongyloides sp., Bunostomum sp., Moniezia sp. and Eimeria sp. were 32.02, 19.78, 8.38, 9.24, 10.53, 5.59 and 14.40%, respectively. The overall prevalence of GI parasite was 49.10%. From the epidemiological survey it was revealed that the prevalence of GI parasitic infestation was high in year round. The age, sex and season were highly enhancing the prevalent rate. Abundant rainfall, availability of intermediate host and other climatic condition enhanced the trematodal infestation in rainy season. The temperature and humidity become optimum for larval development of parasites and favorable for the migration and development of infective stages of snails. The female was affected much than that of male buffalo. The young were less susceptible than that of adult buffaloes. Conclusion: Its an important study for the identification and factors analysis for the occurrence of GI parasites in Sylhet. Only routine deworming practices and hygienic management can minimize the parasitic load of buffaloes in this area.]]>Kohler-Rollefson, I., H.S. Rathore and E.
