摘　　要： 目的了解江苏省生活饮用水中贾第鞭毛虫和隐孢子虫的污染状况,为饮用水水质卫生、安全供水提供科学依据。方法选取江苏省13个设区市的28家水厂,分别采集水源水、自来水厂出厂水、管网末梢水样本(其中水源水采集10 L,出厂水和末梢水各100 L),并进行抽滤、淘洗、离心浓缩、免疫磁分离、荧光染色镜检的处理,检测贾第鞭毛虫包囊及隐孢子虫卵囊的含量。结果累计采集江苏省13个设区市的水样84份,包括水源水、水厂出厂水、管网末梢水各28份。其中,水厂出厂水和管网末梢水中均未检出贾第鞭毛虫包囊和隐孢子虫卵囊,但在盐城(盐龙湖)、连云港(蔷薇河)、常州(钱资湖)水源水中检出贾第鞭毛虫包囊,阳性率为10.71%(3/28),密度均为1个/10 L;在南京(长江)、镇江(长江)、扬州(京杭大运河)的水源水中检出隐孢子虫卵囊,阳性率为10.71%(3/28),密度均为1个/10 L。结论江苏省部分地区水源水中可检出贾地鞭毛虫和隐孢子虫,存在一定的安全用水隐患,须进一步加强水源卫生监管,加强饮用水的监测,保证居民的饮水安全。 Objective To know the contamination status of Giardia lamblia and Cryptosporidium in drinking water of Jiangsu Province,so as to provide the evidence for producing hygiene and safety drinking water. Methods A total of 28 water plants of 13 cities in Jiangsu Province were selected,and the source water（10 L）,chlorinated water（100 L）and tap water（100 L） were collected separately in each site. The water samples were then treated by filtration,washing,centrifuging concentration, immune magnetic separation,and immunofluorescent assay,to detect the numbers of Giardia cysts and Cryptosporidium oocysts. Results Totally 84 samples from 13 cities were collected,including 28 source water,28 chlorinated water and 28 tap water samples. Among the chlorinated water and tap water samples,no Giardia cysts and Cryptosporidium oocysts were found. Howev-er,Giardia cysts were detected in 3（10.71%,3/28）source water samples（Yancheng,Lianyungang,Changzhou cities）,with the density of 1 cyst/10 L of all. Cryptosporidium oocysts were also detected in 3（10.71%,3/28）source water samples（Nan-jing,Zhenjiang,Yangzhou cities）,with the density of 1 oocyst/10 L of all. Conclusions The source water in partial areas of Ji-angsu Province has been contaminated by Giardia and Cryptosporidium. To ensure the safety of drinking,the regulation of source water and surveillance of drinking water should be strengthened.
