Description Not Available
The present study was intended to screen the wild shrimps of Andaman and Nicobar Islands (ANI)
against infectious diseases. A total of 175 shrimp samples (35 pools) consisting of Fenneropenaeus indicus, Penaeus monodon, Penaeus merguiensis and Metapenaeus monoceros were collected from different landing
centres across ANI. Out of 35 pools of samples analysed by polymerase chain reaction (PCR), a total
of 10 pools of Penaeus monodon collected from Betapur (1 pool), Lohabarrack (4 pools) and Campbell Bay
(5 pools) were found positive for Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV).
Nucleotide sequence of IHHNV isolated from ANI showed 100% identity to the sequences of IHHNV
reported from Vietnam, Taiwan, Australia, China, Egypt, USA, Ecuador, 99% identity to IHHNV
reported from Brazil, Venezuela, Korea, 96% identity to IHHNV reported from Thailand and 95% identity
to IHHNV reported from India. Based on phylogenetic tree analysis, IHHNV of ANI is closely related to
IHHNV of Vietnam. Histopathological analysis revealed typical eosinophilic intranuclear cowdry type
A inclusion bodies in gill lamellae which further confirmed he IHHNV infection. The present study provides
a definitive evidence for the first report of infectious IHHNV in wild P. monodon from ANI.
