To know the contamination status of and in drinking water of Jiangsu Province, so as to provide the evidence for producing hygiene and safety drinking water. 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 cysts and oocysts. 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 cysts and oocysts were found. However, 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. oocysts were also detected in 3 (10.71%, 3/28) source water samples (Nanjing, Zhenjiang, Yangzhou cities), with the density of 1 oocyst/10 L of all. The source water in partial areas of Jiangsu Province has been contaminated by and . To ensure the safety of drinking, the regulation of source water and surveillance of drinking water should be strengthened.
了解江苏省饮用水中隐孢子虫和贾第鞭毛虫的污染状况，为生产卫生安全的饮用水提供依据。选取江苏省13个城市的28家水厂，在各采样点分别采集源水（10 L）、加氯水（100 L）和自来水（100 L）。水样经过滤、洗涤、离心浓缩、免疫磁分离和免疫荧光检测，以检测隐孢子虫包囊和贾第鞭毛虫囊合子数量。共采集13个城市的84份水样，包括28份源水、28份加氯水和28份自来水样。在加氯水和自来水样中未发现隐孢子虫包囊和贾第鞭毛虫囊合子。然而，在3份（10.71%，3/28）源水样品（盐城、连云港、常州市）中检测到隐孢子虫包囊，包囊密度均为1个/10 L。在3份（10.71%，3/28）源水样品（南京、镇江、扬州市）中也检测到贾第鞭毛虫囊合子，囊合子密度均为1个/10 L。江苏省部分地区的源水已受到隐孢子虫和贾第鞭毛虫的污染。为确保饮水安全，应加强对源水的监管和饮用水的监测。
