Vaccination as one of prevention strategies against the Trichinella spiralis infection in hosts is an ongoing effort.However,no ideal vaccine candidates have been identified until now.Therefore,identification of more effective antigens in essential life stages of the parasite as vaccine candidates is of importance.In the present study,we identified a novel aquaporin gene in T.spiralis(TsAQP),and the potential antigenicity of TsAQP was evaluated by prediction of epitopes.
