Description
Summary: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%–69.5% sequence identities with all known HPVs and carried unique amino acid deletions and insertions in the VP gene. According to phylogenetic analysis, the Taiwan HPV isolates were classified as the genotype IV. The present study not only provided the histopathological and molecular proof of HPV and EHP co‐infection in Taiwan, but also revealed the importance of investigating the geographical expansion of novel HPV genotypes.
