Abstract:

Hepaotopancreatic Microsporidiosis (HPM) caused by Enterocytozoon hepatopenaei (EHP), a microsporidian parasite to be associated with slow (retarded or stunted) growth and white feces syndrome (WFS) in cultured shrimp in many of the shrimp growing countries in Asia, also in India. In the present study, shrimp samples from various shrimp ponds from different Mandals of SPSR Nellore district, Andhra Pradesh, India, were collected over a period of five months (February 2016 to June 2016). Important diagnosis observed were histopathological studies, molecular technique (PCR). Histologically, the infected animals showed severe degeneration of hepaotopancreatic tubule, basophilic inclusions resembling the developmental stages of EHP were found in the epithelial cells and large number of spore aggregations was observed in the tubular lumen. Enlargement of haemal sinuses was also observed in some cases. From this study, out of 50 pond case studies, 31 cases were showing EHP symptoms with 62 % prevalence by using tools of detection like PCR and histology.
