新疆自来水和河水中隐孢子虫污染状况调查

Investigation of river and runing water contaminated with Cryptosporidium in Xinjiang

目的了解新疆10个城市自来水和河水隐孢子虫污染情况。方法对水样品用微孔滤膜过滤、蔗糖溶液梯度分离和磁抗体分离法分离纯化,免疫荧光染色鉴定。结果4个城市的河水检测出隐孢子虫卵囊,10个城市的自来水中隐孢子虫检测为阴性。结论新疆部分城市河水已被隐孢子虫污染。

Objective To know the contamination of Crytosporidium parvum in river and tuning water in ten cities of Xinjiang. Methods Water samples were detectcd by following steps： filtering, sucrose gradient centrifugation, immunity magnetic seperation （IMS） and immunofluorescent assay （IFA）. Results Cryptosporidium parvum was not found in runing water of all ten cities, but detected in river water of four cities. Conclusion The rivers in some cities of Xin- jiang were contaminated with C. parvum.
