Abstract: To establish a rapid assay for detection of Vibrio parahaemolyticus(VP), Real-time PCR method was developed targeting to toxR gene of Vibrio parahaemolyticus.The results showed that the test for 15 bacteria strains using the Real-time PCR method, only Vibrio parahaemolyticus test was positive, indicating that the method had high specificity.In addition, the sensitivity of Real-time PCR was 4.9 CFU/mL.Furthermore, a total of 3 positive samples for Vibrio parahaemolyticus were detected from 150 clinical samples by the Real-time method, which was in accordance with the testing result by GB 4789.7-2013 standard detection protocol.Therefore, the Real-time method provided a novel rapid and sensitive detection method with good practicality for Vibrio parahaemolyticus infection.

Key words: Vibrio parahaemolyticus(VP); toxR gene; Real-time PCR
