Epidemiology of Food Poisoning Caused by Vibrio Parahaemolyticus and Its Drug Resistance in Shenzhen

Objective To understand the epidemiological characteristics of food poisoning caused by Vibrio Parahaemolyticus and its drug resistance in Shenzhen,and provide evidence for the control of Vibrio parahaemolyticus related food poisoning.Methods The sample collection from food poisoning cases was started in 2006.Vibrio Parahaemolyticus was isolated according to GB/4789.7-2003,and identified by GNID.The serotype was determined by slide agglutination.The drug susceptibility was conducted by ATB Fungus method of bio-Meieux,France.Results The peak season of Vibrio parahaemolyticus related food poisoning was during July-October.The majority of foods causing poisoning were cold dish and meat products which was not fully heated.O3:K6 was the predominant serotype of Vibrio Parahaemolyticus strains(52.4%).Most strains showed resistance to ampicillin(61.5%),ticarcillin(50.0%) and cefazolin(42.3%).Conclusion It is important to control the food poisoning caused by Vibrio parahaemolyticus O3:K6 serotypes.The antibiotics should be used rationally in the treatment of related disease.
