宁波市感染性腹泻患者致病性弧菌和气单胞菌分布的研究

A Study on Distribution of Pathogenic Vibrio and Aeromonas among Infectious Diarrhea Patients in Ningbo

目的了解宁波市感染性腹泻患者致病菌中致病性弧菌和气单胞菌的分布情况,为致病性弧菌和气单胞菌引起的感染性腹泻提供防治依据。方法对宁波市2008—2011年肠道门诊监测点采集的9256份粪便标本进行病原分离鉴定。结果检出沙门菌、志贺菌、致病性弧菌、气单胞菌等8类16种病原菌共3473株,检出率为37.52%;其中致病性弧菌4种2167株,气单胞菌5种318株,合计2485株,检出率为26.85%;检出的病原菌以副溶血性弧菌为最多,占检出病原菌的55.95%。结论致病性弧菌尤其是副溶血性弧菌是本地区感染性腹泻病原菌主要组成部分。

Objective To explore the distribution of pathogenic vibrio and aeromonas among infectious diarrhea patients in Ningbo. Methods Regular isolation and identification of pathogen were used to detect 9256 feces and anus swabs from infected diarrhea patients who were eolleeted from 2008 to 2011. Results The total numbers of pathogen detected were 3473 strains, including 8 categories and 16 kinds. The total detected rate was 37.52%. 2485 detected strains were identified belonging to pathogenic vibrio and in which 2167 belonged to 4 kinds of pathogenic vibrio and 318 belonged to 5 kinds of aetomonas. The detected rate of pathogenic vibrio and was 26.85%. The most detected strains were vibrio parahaemolyticus with a detected rate of 55.95%. Conclusion Pathogenic vibrio is the main component of pathogen of infectious diarrhea in Ningbo.
