ABSTRACT: Decapod hepanhamaparvovirus 1 (DHPV), also known as hepatopancreatic parvovirus (HPV), has caused death in larvae or stunted growth in juveniles of cultured shrimp. To date, 4 genotypes (genotype I, II, III, and IV) have been reported from various shrimp species and various geographical regions. In the present study, we isolated 2 types of DHPV (GHPV-Goseong and DHPV-Geoje) from cultured Penaeus vannamei in Korea. Based on the capsid protein (VP) amino acid sequences, DHPV-Goseong was highly identical to previously reported DHPV genotype IV in Taiwan and Korea. Different from DHPV-Goseong, DHPV-Geoje showed approximately 63% similarity with DHPV genotype I, II, III and 84% similarity with DHPV genotype IV, suggesting an independent new genotype of DHPV (genotype V). Further research is needed to elucidate the origin and biological meanings of the present new genotype.
