Vibrio parahaemolyticus has been considered as one of the most important food-borne bacterial pathogens. Because of the safety concerns, detection and characterization of V. parahaemolyticus have attracted much attention. In this study, electrochemiluminescence polymerase chain reaction (ECL-PCR) method combined with universal probes hybridization technique was applied to rapid detection of V. parahaemolyticus, infected and uninfected sea foods for the first time. Whether the sea food samples were infected was discriminated by detecting the gyrase B (gyrB) gene. We detect V. parahaemolyticus both in artificially contaminated sea foods and natural samples. The experiment results show that the infected and uninfected sea food samples can be clearly identified and the detection limit for V. parahaemolyticus is 1.6 pg purified genomic DNA in the presence of 1 μg non-specific background DNA. The technique may provide a new means in V. parahaemolyticus detection due to its simplicity and high efficiency.
