摘　　要：目的通过了解2009—2011年间深圳市龙岗区急性感染性腹泻的流行病学特征,以便及时采取措施以防传染病疫情暴发流行。方法选择每日排便≥3次的患者作为研究对象,在患者未使用抗菌药物之前进行大便细菌病原学检验并进行描述性统计分析。结果共检测1 807份标本,检出病原菌500株,阳性率为27.67%,以中青年发病居多;500株病原菌中居前3位的是产毒性大肠埃希菌、致病性大肠埃希菌和副溶血弧菌,其分别分离出172株(34.4%)、143株(28.6%)和68株(13.6%);检测出1例O157:H7致病菌;秋冬季检出致病菌359株(71.8%),高于春夏季141株(28.2%)。结论要针对各病原菌检出率的差异在不同季节开展相应的预防控制措施,还要结合地域的特点对特定的病原菌进行重点监测。[Objective]By understanding the epidemiological characteristic of acute infectious diarrhea in Longgang District of Shenzhen City from 2009-2011,to promptly carry out the measures for preventing outbreaks of infectious diseases.[Methods]Patients having defecation more than 3 times a day were collected for the study,the examination of pathogenic bacteria was performed in the fecal specimens before antimicrobial therapy,and the results were analyzed with descriptive statistics.[Results]Among 1 807 specimens,500 strains of pathogenic bacteria were isolated with the positive rate of 27.67%,and most of the patients were young and middle-aged people.The top three pathogenic bacteria were Enterotoxigenic Escherichia coli,Pathogenic Escherichia coli and Vibrio parahaemolyticus,which were isolated from 172 strains（34.4%）,143 strains（28.6%） and 68 strains（13.6%）,respectively.One cases of O157∶ H7 pathogen has been detected.359 strains of pathogenic bacteria were isolated in autumn and winter,which were more than 141 strains（28.2%） in the spring and summer.[Conclusion]It is necessary not only to carry out prevention and control measures according to the differences in the detection rate of pathogen during different seasons,but also to monitor the specific pathogenic bacteria based on the geographical characteristics.
