隐孢子虫是一类寄生于人和动物体内的肠道原虫,饮用含有其原虫卵囊的水可引起消化道感染,导致腹痛腹泻表现。隐孢子虫呈世界性分布,人群普遍易感,特别是老年人、儿童、吸毒人员、慢性乙肝患者以及HIV/AIDS等免疫功能低下者更易感染,其暴发流行多见于气候温暖与多雨季节。我国现行《生活饮用水卫生标准》(GB5749-2006)在微生物学指标中增加了隐孢子虫指标,在监测过程中,由于水样量大,富集较困难,检测回收率低,检测费用比较高,在农村地区难以实施。赤壁市在中国疾病预防控制中心改
Cryptosporidium is a type of intestinal protozoan parasites in humans and animals, drinking water containing its protozoa oocysts can cause gastrointestinal infections, leading to abdominal pain and diarrhea. Cryptosporidium is a worldwide distribution, the population is generally susceptible, especially for the elderly, children, drug addicts, chronic hepatitis B and HIV / AIDS and other immunocompromised persons more susceptible to the outbreak of epidemic more common in warm and rainy weather season. China’s current “Sanitary Standard for Drinking Water” (GB5749-2006) added indicators of Cryptosporidium in microbiological indicators, in the monitoring process, due to large water samples, enrichment is more difficult, the detection recovery is low, the test cost comparison High, difficult to implement in rural areas.
