Assessment of Incidence of Enterocytozoon hepatopenaei (EHP) in Penaeus vannamei in Maharashtra and Gujarat

The occurrence of Enterocytozoon hepatopenaei in Penaeus vannamei samples were collected from Maharashtra and Gujarat farms. In the present study, shrimp samples from various shrimp ponds from two districts of Maharashtra and two districts of Gujarat were collected over a period of one year (February 2016 to April 2017). A total of 4513 shrimp samples were assessed for the presence of EHP by molecular characterization. Out of shrimp samples analysed, 31.2% samples were positive for EHP. The screening of EHP was done by single step and nested PCR targeting spore wall protein gene (SWP) of EHP resulting in product size of 514 bp and 148 bp for EHP respectively
