pirAB^vp -Bearing Vibrio parahaemolyticus and Vibrio campbellii Pathogens Isolated from the Same AHPND-Affected Pond Possess Highly Similar Pathogenic Plasmids.

ABSTRACT: Acute hepatopancreatic necrosis disease (AHPND) is a severe shrimp disease originally shown to be caused by virulent strains of Vibrio parahaemolyticus (VP_AHPND). Rare cases of AHPND caused by Vibrio species other than V. parahaemolyticus were reported. We compared an AHPND-causing V. campbellii (VC_AHPND) and a VP_AHPND isolate from the same AHPND-affected pond. Both strains are positive for the virulence genes pirAB^vp . Immersion challenge test with Litopenaeus vannamei indicated the two strains possessed similar pathogenicity. Complete genome comparison showed that the pirAB^vp -bearing plasmids in the two strains were highly homologous, and they both shared high homologies
