Abstract:

The effects of three inhibitors(ethylenediaminetetraacetic acid (EDTA), sodium nitrite and magnesium chloride) on the bacterial motilities of Vibrio parahaemolyticus were investigated by testing the flagellum-mediated swimming, flagellum-mediated swarming, and type IV pilus-mediated twitching on different plates. The motilities were evaluated by measuring the size of colony in the culture adding with EDTA, sodium nitrite and MgCl2, respectively. The results showed that the three types of the motilities could be inhibited by EDTA, sodium nitrite, and magnesium chloride, and the effective concentrations of the three inhibitors in plates were 0.10 mmol/L, 50 mg/L, and 15.0 g/L, respectively. The results indicated that EDTA, sodium nitrite, and magnesium chloride have the strong influence on the motilities of Vibrio parahaemolyticus, so the three inhibitors can effective control the contamination of Vibrio parahaemolyticus.
