摘要
目的利用感染性腹泻病原体监测了解深圳市福田区感染性腹泻分布情况及流行病学特征。方法设置哨点医院采集门诊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,疾病预防控制中心对阳性菌株进行复核和分析。结果福田区腹泻病例肠道致病菌感染率为8.59%,检测出病原体为副溶血性弧菌,致泻性大肠埃希菌中的EPEC、EIEC、ETEC,不同性别、年龄段和户籍分布差异无统计学意义(P>0.05)。副溶血性弧菌感染情况不同季节感染情况不同,秋季较多见,差异有统计学意义(P=0.000)。致泻性大肠埃希菌中的EPEC、EIEC、ETEC感染不同季节差异无统计学意义。结论福田区感染性腹泻以致泻性大肠埃希菌的EPEC、EIEC、ETEC为主。
Objective To understand the infection status of diarrhea in Futian xtistrict,analyze its epidemiological characteristics, and provide measures of treatment and prevention. Method Stool samples, rectal swabs or vomit samples were collected from diarrhea patients without using any antibiotics from the sentinel hospitals for the isolation and culturing the pathogenic bacteria and analysis of the molecular characteristics of the positive strains. Results The infection rate of pathogenic intestinal bacteria was 8.59% （80/931）. The detected pathogens were Vibrio parahaemolyticus, diarrheagenic Escherichia coli of EPEC, EIEC and ETEC. The infection rates had no significance differences in gender, age or household register （P〉0.05）. The infection rates of EPEC, EIEC and ETEC showed no seasonal differences, but that of Vibrio parahaemolyticus showed seasonal difference and more often in autumn （P=0.000）. Conclusion Infectious diarrhea in Futian district was mainly caused by Escherichia coli of EPEC, EIEC and ETEC.
