Abstract
Juvenile shrimps (Penaeus monodon) weighing about 15-20 gms were procured from the grow-out ponds and reared under laboratory conditions. They were challenged with Vibrio parahaemolyticus MTCC 451 and their LD50 value was evaluated. The ascorbic acid and the histamine activity of both the control and experimental groups were assessed. The results showed a marked decline in both the parameters at all intervals. This reveals the pathogenesis of the inoculated bacterial strain, which affects the defense mechanism by reducing the glutathione content by the decreased level of ascorbic acid and letharginess by the decreased histamine content of the experimental prawns.
