Abstract:
Objective To investigate the effect of salinity and temperature on motility of Vibrio parahaemolyticus. Methods V.parahaemolyticus was inoculated on swarming or swimming agar plates containing different amounts of salinity (0.5%, 1.0%, 2.0%, and 4.0% NaCl, respectively), followed by incubation at 26 or 37℃, before the diameters of bacterial lawns were measured .Results and Conclusion The swarming motility was not affected by salinity , while the swimming motility was positively correlated with salinity .Maximum swimming occurred in 2.0% NaCl, and displayed a slight decline in salinity of 4.0%.Both swimming and swarming were affected by temperature , and the motility was signifi-cantly enhanced in 37℃vs 26℃.These results indicate that both salinity and temperature can modulate the motility of V. parahaemolyticus.
