Objective Establish detection method to measure Vibrio vulnificus rapidly and accurately.MethodsUsing flow cytometry(FCM)and a 5'-FITC fluorescent labeled aptamer with high binding affinity to detect Vibrio vulnificus rapidly.Measure a series of concentrations of Vibrio vulnificus to identify the Limit of Blank, Lower Limit of Detection, Linearity Range, etc.ResultsCombined application of FCM and the aptamer can detect Vibrio vulnificus rapidly with the duration less than 1 hour and lower limit of detection as low as 29 CFU/mL.Conclusion The aptamer targeting Vibrio vulnificus is an excellent detective element, while FCM can realize accurate quantitative detection.The detection method has great application potential.
