Sensitivity of diagnostic methods for detection HPV infection at earlier stages of shrimp is very important for the prevention of widespread and losses in shrimp hatcheries. The earliest postlarval stage detected with HPV infection was 3 days old (PL₃). The presence of hypertrophied nucleus in the hepatopancreas tubule epithelial cell diagnostic of HPV intranuclear inclusion body is indicative of HPV infection. Histological method (H and E) was significantly (P less than 0.01) sensitive than impression smear in the diagnosis of HPV infection in Penaeus monodon postlarvae (PL₃ to PL∧29) reared at two stocking densities (25 and 50 PL/liter).
