实验室规模的实验确定了不同剂量的多色紫外线（UV）辐射对微小隐孢子虫卵囊的杀菌效果。用中压连续波紫外线灯或脉冲紫外线灯发出的多色光照射悬浮在处理过的地表水中的微小隐孢子虫卵囊，然后用人类细胞培养技术进行分析。使用大于或等于16 mJ/cm2的脉冲紫外线剂量进行的实验提供了微小隐孢子虫悬浮卵囊的gt2对数灭活。在较低紫外剂量下的实验建立了与中压和脉冲紫外灯的剂量响应关系。当在同等剂量的基础上比较两种光源的消毒结果时，两种介质的消毒能力没有统计学差异- 压力和脉冲紫外线灯。两种灯的结果表明，低至7.5和11 mJ/cm2的紫外线剂量可提供灭活 微小隐球菌感染性卵囊的比率为1对数（90%）和2对数（99%）， 分别地作者还研究了异养细菌的紫外线消毒 细菌和大肠杆菌。他们发现异养细菌对紫外光的反应在统计学上与微小梭菌不同，而大肠杆菌对紫外光的反应在统计学上与微小梭菌没有差异。这表明大肠杆菌可能是紫外线技术提供的微小隐球菌消毒的替代生物。包括39个参考文献、表格和图表。

Bench-scale experiments determined the germicidal effects of varying dosages of polychromatic ultraviolet (UV) radiation on oocysts of Cryptosporidium parvum. C. parvum oocysts suspended in treated surface water were irradiated with polychromatic light emitted by either a medium-pressure, continuous-wave UV lamp or a pulsed-UV lamp then assayed with human cell culture techniques. Experiments conducted using pulsed-UV doses of greater than or equal to 16 mJ/cm2 provided >2-log inactivation of suspended oocysts of C. parvum. Experiments at lower UV dosages established a dose-response relationship with both the medium-pressure and pulsed-UV lamps. When disinfection results from both light sources were compared on an equivalent dosage basis, no statistical difference in disinfection power was found between the medium-pressure and pulsed-UV lamps. Results from both lamps showed that UV doses as low as 7.5 and 11 mJ/cm2 provided inactivation of infectious oocysts of C. parvum at rates of 1 log (90%) and 2 log (99%), respectively. The authors also examined UV disinfection of heterotrophic bacteria and Escherichia coli. They found the response of heterotrophic bacteria to be statistically different from that of C. parvum, whereas E. coli's response to UV light did not statistically differ from that of C. parvum. This suggests that E. coli may be a surrogate organism for C. parvum disinfection provided by UV technologies. Includes 39 references, tables, figures.
