Aims: To develop a multiplex PCR targeting the gyrB and pntA genes for Vibrio species differentiation. Methods and Results: Four pairs of primers targeting gyrB gene of Vibrios at genus level and pntA gene of Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vulnificus were designed. This PCR method precisely identified 250 Vibrio species and demonstrated sensitivity in the range of 4 -104 CFU ml-1 (c. 200 CFU per PCR) to 2 -103 CFU ml-1 (c. 10 CFU per PCR). Overall, the gyrB gene marker showed a higher specificity than the dnaJ gene marker for Vibrio detection and was able to distinguish Aeromonas from Vibrio species. Conclusions: The multiplex PCR based on combined gyrB and pntA provides a high discriminatory power in the differentiation between Vibrio alginolyticus and V. parahaemolyticus, and between V. cholerae and Vibrio mimicus. Significance and Impact of the Study: This assay will be useful for rapid differentiation of various Vibrio species from clinical and environmental sources and significantly overcomes the limitations of the conventional methods.
