Increased susceptibility of white spot syndrome virus-exposed Penaeus vannamei to Vibrio parahaemolyticus causing acute hepatopancreatic necrosis disease

In this study, co-infection of white spot syndrome virus (WSSV) and AHPND-Vibrio parahaemolyticus (VpAHPND), was studied in juvenile Penaeus vannamei under the laboratory condition. Experimental shrimp were divided into 4 groups (group 1: WSSV only; group 2: VpAHPND only; group 3: WSSV + VpAHPND; group 4: not challenged), and for the co-infection, shrimp were challenged with dual pathogens (initially exposed to WSSV and subsequently exposed to...
