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