Abstract

During June - July, 1995, a severe epizootic epidemic with heavy mortality occurred in cultured Penaeus monodon near Chidambaram, Tamil Nadu. The clinical symptoms and gross lesions observed resembled infectious hypodermal and haematopoietic necrosis virus (IHHNV) disease. Histological examination of the affected shrimp revealed prominent Cowdry type-A eosinophilic intranuclear inclusions within chromatin marginated and hypertrophied nuclei of cells of ectodermal and mesodermal tissues. Transmission electron microscopy sections of gills revealed intranuclear inclusions and paracrystalline arrays of icosahedral IHHNV particles in the cytoplasm. This is perhaps the first conclusive evidence of IHHNV in cultured P. monodon in Tamil Nadu, India.
