2004-2013年北京市外环境及食品中霍乱弧菌监测结果分析

Surveillance for Vibrio cholerae in environment and food in Beijing,2004-2013

  • 摘要: 目的 了解北京市外环境及食品中霍乱弧菌污染状况,为人间霍乱疫情防控提供科学依据。方法 2004-2013年,每月均在全市的16个区(县)采集地表水、游泳池水、养殖池水、水产品、熟食、其他等6类样品,分别进行霍乱弧菌培养,对培养结果应用描述流行病学的方法进行分析。结果 2004-2013年养殖池水和其他类别样品的霍乱阳性率最高,分别为1.16%(44/3808)和1.48%(61/4135);游泳池水中未检出霍乱弧菌;外环境疫情在北京市集中在城近郊区,呈环形分布;牛蛙和甲鱼检测阳性率较高,霍乱毒素(cholera toxin, CT)阳性疫情较少,占检测总起数的9.09%(5/55),且均为水产品涂抹疫情。2007年以来,霍乱外环境疫情较少,O139群霍乱弧菌污染呈下降趋势,O1群稻叶型则有所增多。结论 北京市霍乱弧菌污染较轻,且检出菌株也以CT阴性菌株为主,对人体威胁较小。

     

    Abstract: Objective To understand the contamination status of Vibrio cholerae in environment and food in Beijing, and provide evidence for the prevention and control of V. cholerae infection in human. Methods From 2004 to 2013,Six types of samples, including surface water, swimming pool water, aquaculture water, aquatic products, cooked food and others, were collected monthly from 16 districts and counties in Beijing. V. cholera was cultured by using these samples and a descriptive epidemiologic analysis was conducted. Results The positive rates of V. cholerae were high in aquaculture water samples(1.16%, 44/3808) and other type samples(1.48%, 61/4135). The detection results were all negative in swimming pool water samples. The environmental V. cholerae positive samples were mainly distributed in suburb around urban area. The detection rates in bullfrog and soft-shelled turtle were high. A small number of CT toxin positive V. cholerae samples were identified, accounting for 9.09%(5/55) of the total and all of these samples were from swabs of aquatic products. Since 2007,less cholera outbreaks occurred in environment. Contamination of V. cholerae O139 tended to decrease, while the contamination of V. cholerae O1 Inaba serotype was in increase. Conclusion In Beijing, the contamination of V. cholerae is relatively mild and the CT toxin negative strain is predominant, indicating the lower risk to human health.
