[Application of pulse-field gel electrophoresis analysis in source-tracking of food-borne disease caused by Vibrio parahaemolyticus].

Objective: To apply pulse-field gel electrophoresis analysis(PFGE) in analysing a case of food poisoning caused by Vibrio parahaemolyticus.

Methods: PFGE using restriction enzyme Not I was employed in molecular subtyping of thirty strains of V. parahaemolyticus isolated from a case of food poisoning in Guangzhou city and PFGE patterns were analyzed by using BioNumerics Version 4.
