Abstract
The results of batch-process solar disinfection (SODIS) of Cryptosporidium parvum oocysts in water are reported. Oocyst suspensions were exposed to simulated sunlight (830 W m(-2)) at 40 degrees C. Viability assays (4',6'-diamidino-2-phenylindole [DAPI]/propidium iodide and excystation) and infectivity tests (Swiss CD-1 suckling mice) were performed. SODIS exposures of 6 and 12 h reduced oocyst infectivity from 100% to 7.5% (standard deviation = 2.3) and 0% (standard deviation = 0.0), respectively.
摘要
报告了水中微小隐孢子虫卵囊的间歇式太阳能消毒（SODIS）结果。将卵囊悬浮液在40℃下暴露于模拟阳光（830 W m(-2)）。进行了活力测定（4',6'-二脒基-2-苯基吲哚[DAPI]/碘化丙啶和脱囊）和感染性测试（瑞士CD-1乳鼠）。6小时和12小时的SODIS暴露分别将卵囊感染性从100%降低到7.5%（标准差=2.3）和0%（标准差=0.0）。
