Abstract

A histopathological study of Penaeus monodon show-ing external symptoms of white spot disease, collected from culture ponds at Mulakuddu and Rambilli villages (Visakhapatnam District) during May and July 2001, provided evidence for the occurrence of multiple viral infections. Each diseased shrimp carried concurrent infections with four different viruses, identified on the basis of nuclear changes, resulting in the formation of characteristic inclusion/occlusion bodies, as WSSV, YHV, MBV and IHHNV. The iden-tification of the various viruses needs confirmation through molecular diagnostic methods. This consti-tutes a report recording concurrent infections with multiple viruses in a single shrimp.
