Dietary supplementation with probiotic Rhodobacter sphaeroides SS15 extract to control acute hepatopancreatic necrosis disease (AHPND)-causing vibrio parahaemolyticus in cultivated white shrimp.

Cultivation of Penaeus vannamei (Pacific white shrimp) is faced with the serious problem of acute hepatopancreatic necrosis disease (AHPND), caused by Vibrio parahaemolyticus that carries plasmids containing binary toxin genes. The disease is typically moderated by the use of antibiotics. To investigate the control of AHPND and maintenance of water quality without the use of antibiotics, the supplementation of shrimp feed with anti-vibrio compounds from a crude extract of probiotic Rhodobacter sphaeroides SS15 was evaluated.
