In recent years, several pathogens have emerged and caused heavy mortality in Asia. In this study, we investigated the prevalence of pathogens in specimens of whiteleg shrimp (Penaeus vannamei) collected from greenhouse ponds. In total, six pathogens were tested in these shrimp, three of which, including Enterocytozoon hepatopenaei (EHP), acute hepatopancreatic necrosis disease (AHPND)-causing Vibrio parahaemolyticus and infectious hypodermal and haematopoietic necrosis virus (IHHNV), were detected in shrimp aquaculture, with EHP being the most prevalent; Taura syndrome virus (TSV), White spot syndrome virus (WSSV) and yellow head virus (YHV) were not detected in these samples. Ultrastructure examination revealed the presence of a large number of EHP spores infecting hepatopancreatic epithelial cells of shrimp. Body weight (BW), body length (BL) and BW/BL ra.. View More»
