A survey on cryptosporidium parvum cryptosporidiosis in different people of Luwan district Shanghai

[目的]探讨中心城区不同人群隐孢子虫感染情况,为预防隐孢子虫病提供科学依据。[方法]采用改良抗酸染色法筛选,间接免疫荧光法(IFA)确定隐孢子虫感染情况。[结果]共收集不同人群粪样500份,隐孢子虫感染率为4.80%,其中腹泻病人隐孢子虫感染率为5.30%,养狗家庭居民隐孢子虫感染率为13.33%,社区居民无隐孢子虫感染。病例对照调查显示,食不洁食物、食品生熟交叉污染及家庭养狗是隐孢子虫感染的危险因素。[结论]中心城区腹泻病人和养狗居民存在隐孢子虫感染,应该加强宣传。注意饮食和个人卫生,饲养宠物家庭注意宠物卫生,不玩宠物并养成勤洗手的好习惯,是预防隐孢子虫感染的有效方法。
