Penaeus monodon densovirus (PmDNV) is one of the major causes of stunted shrimp in the aquaculture industry in Thailand. Significant reductions in levels of PmDNV as assessed by PCR analysis of shrimp hepatopancreas were seen in both prophylactic and curative experiments after feeding shrimp with a formulated diet containing mixed inactivated bacteria harboring dsRNAs corresponding to the PmDNV ns1 and vp genes. Significant reductions of approximately 88% (prophylactic) and 64% (curative) of PmDNV were observed, suggesting that this diet has a high potential for application in commercial aquaculture for reducing PmDNV associated stunted growth of shrimp.
