Objective:To analyze the effects of salinity and temperature on the survival rate and motility of Vibrio parahaemolyticus.Method:Using a single-factor controlled variable method,the survival rate and colony diameter of Vibrio parahaemolyticus were measured under different temperatures and salinities.The experimental results were subjected to single-factor analysis of variance and multiple comparison analysis.Result:The study found that the temperature and salinity significantly affected the survival rate and motility of Vibrio parahaemolyticus.The highest survival rate and motility were observed at a temperature of 36℃.Below 15 ℃,the bacteria ceased to grow and showed no motility.The optimal salinity for survival rate was 3％,while the best motility was recorded at 4.5％salinity.The survival rate and motility were significantly higher than other experimental groups at 3.0％and 4.5％salinity(P＜0.01).Conclusion:Temperature and salinity are crucial factors in regulating the survival rate and motility of Vibrio parahaemolyticus.
