Concurrent infection of a novel genotype of hepatopancreatic parvovirus and Enterocytozoon hepatopenaei in Penaeus vannamei in Taiwan.

Hepatopancreatic parvovirus (HPV) and Enterocytozoon hepatopenaei (EHP) are emerging and reemerging pathogens in shrimps. In the present study, a novel genotype of HPV concurrently infected with EHP in Penaeus vannamei in Taiwan leading to severe atrophy and damage of hepatopancreas were confirmed by histopathology, in situ hybridization, and PCR. The novel genotype of HPV exhibited 66%-69.
