Objective: To determine the prevalence of schistosomiasis in the fishermen community in Egypt.\udMethods: A cross-sectional survey for schistosomiasis mansoni was conducted among 150\udfishermen and their families from January to November 2013. Faecal samples were examined\udby Kato Katz method and formalin-ether concentration technique. Malacological survey was\udconducted to identify infection of the snail intermediate host by larval stage of Schistosoma\udmansoni. Snails were collected and checked for shedding of cercariae after light exposure.\udResults: Overall prevalence of infection was 26.6% with an intensity of (42.7依7.2) ova/g of stool.\udInfection was common in male and significantly increased in the age of 20-40 years. Praziquanteltreated individuals had a high significant decrease in intensity (27.2依2.4) ova/g of stool than\udthose with no treatment history. Biomphalaria alexandrina snail was infected with Schistosoma\udmansoni particularly in warm seasons and mice infection was established successfully from the\udshed cercariae, moreover adult worms were obtained via portal perfusion of the infected mice.\udConclusions: Findings indicated the endemicity of schistosomiasis mansoni in Lake Manzala\udregion, therefore, appropriate integrated control measures are needed among fishermen including\udhealth education, environmental sanitation, periodic screening and mass treatment with\udpraziquantel
