Whitespot virus could be experimentally transmitted from infected Penaeus monodon to P. indicus and repeatedly passed on through several batches of apparently healthy P. indicus . During these passages, white spots first disappeared before subsequently reappearing. Electron microscopic studies revealed the presence of oblong-shaped, fully-assembled virus towards the periphery and virus in paracrystalline arrays towards the center of the hypertrophied nuclei. The virus isolated here is referred to as whitespot syndrome baculovirus (WSBV) until more is known of its antigenic and genomic relatedness to isolates from other countries.
