Isolation and Identification of Vibrio campbellii as a bacterial pathogen for luminous vibriosis of Litopenaeus vannamei

摘要：

　　Outbreak of luminescent disease was reported from Litopenaeus vannamei shrimp farms in Zhangpu County,Southern China during May-July,2011.The clinical signs included fluorescent,less food consumption and high mortality.Bacteria were isolated from the infected shrimps.The pathogen,a luminescent bacterium named VH1 was identified as Vibrio campbellii based on MLSA analysis (16S rDNA,rpoD and toxR).The haemolysin (hly) gene specific in V.campbellii was detected in strain VH1.Pathogenicity test by immersion infection confirmed thatstrain VH1 was virulent to Litopenaeus vannamei post larvae and juveniles,and the LC50 value was 1.55×106CFU mL-1 and 1.7×106CFU mL-1,respectively.
