Abstract:Acute hepatopancreatic necrosis disease (AHPND) caused by Vibrio parahaemolyticus has been one of the most problematic diseases in marine shrimp aquaculture throughout Southeast Asia and Latin America. To evaluate the effectiveness of a bacteriophage (phage) treatment for AHPND, a series of bioassays were carried out in a marine shrimp (Penaeus vannamei) model using an AHPND-V. parahaemolyticus strain that is highly pathogenic to shrimp. We monitored the mortality and histopathological changes during phage treatment. Shrimps treated with phage prophylaxis and phage therapy displayed significant protection from AHPND and survived a lethal bacterial challenge.
