摘　　要：目的掌握从2008年1月至2013年12月福田区腹泻病哨点监测医院分离的145例副溶血性弧菌阳性病例的流行特征及血清分型,为控制副溶血性弧菌引起的腹泻病提供依据。方法福田区哨点医院门诊采集未使用抗生素腹泻监测病例的大便样本、肛拭子或呕吐物标本,进行致病菌的分离培养,对分离出的副溶血性弧菌感染年龄段、流行季节及血清型别进行分析。结果 5 980份标本共分离到145株副溶血性弧菌,2008、2009年的发病率较高,分别为32.41%、24.14%;阳性病例主要集中在20-和30-岁年龄组,10岁以下年龄组少见。副溶血性弧菌的发病高峰在6-9月,血清型以O3：K6为主（64.14%）。结论本区腹泻患者由副溶血性弧菌引起的比例较高,以青壮年为主,O3：K6为优势血清型,掌握副溶血性弧菌的发生规律,可有效预防和控制食源性疾病的发生。Objective To study the epidemiology and serotype of 145 Vibrio parahaemolyticusin diarrhea patients during Jan2008-Dec 2013 for the prevention and control of diarrhea caused by V. parahaemolyticus. Methods Stool samples, rectal swabs or vomit samples of no use antibiotics cases in sentinel hospitals were collected for the isolation isolate and culturing of pathogenic bacteria. Epidemiological features such as age distribution,seasonality and serotype of V. parahaemolyticus were analyzed. Results There were 145 V.parahaemolyticus isolated from 5 980 stool samples. The positive rates of 20- years age group and 30- years age group were the highest,while the positive rate of the children age below 10 years old was the lowest.The peakwas between June and September and the main serotype was O3 ：K6（64.14%）. Conclusions Diarrhea was mainly caused by V. parahaemolyticus infection in Futian. O3：K6 was the predominant serotype.It is essential to understand the incidence pattern of V.parahaemolyticus infection for the effective prevention and control of food borne diseases.
