Molecular genetic makers for Vibrio parahaemolyticus－A review

Abstract:

Abstract:Vibrioparahaemolyticus is an important foodborne pathogen，of which the O3:K6 serotype caused many outbreaks in different countries since 1996．Based on the 10 years data (1992-2001) from China，gastroenteritis caused by Vibrio parahaemolyticus accounted for 31. 1% of foodborne disease outbreaks that were resulted from microorganisms．Most environmental strains ofVibrioparahaemolyticus are non-pathogenic strains．However，clinical strains can producethermostable direct hemolysin (TDH)，TDH-related hemolysin，and other virulence factors．Here we reviewed three commonly used molecular markers forVibrioparahaemolyticus，including species-specific genes，the virulence genesand pandemic group-specific genes，so that to provide references for the rapid detection of Vibrio parahaemolyticus and the identification of its pathogenic factor.
