[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。
[Objective] To investigate the prevalence of Cryptosporidium in different populations in central urban area and provide a scientific basis for preventing Cryptosporidiosis. [Method] The infection of Cryptosporidium was confirmed by improved acid-fast staining and indirect immunofluorescence (IFA). [Results] A total of 500 fecal samples from different populations were collected, the infection rate of Cryptosporidium was 4.80%. The infection rate of Cryptosporidium in diarrhea patients was 5.30%, and the infection rate of Cryptosporidium in residential dogs was 13.33% Sporidium infection. Case-control surveys show that dirty food, cross contamination of raw and cooked foods and domestic dogs are risk factors for Cryptosporidium infection.
