Frequently it is necessary to search for oocysts of Cryptosporidium sp. in the stools potentially contaminated with human immunodeficiency virus (HIV). For the protection of the laboratory personal handling fecal material formalin has been considered useful. However, this disinfectant has not been evaluated when the stool examinations were performed with the technique of flotation-centrifugation in concentrated solution of sugar and with that of "Coprotest". Our experience indicates that the use of formalin may interfere with the results when the first of these methods is used, but it does not alter the results of the second one. This information is of importance for the future assistential and scientific studies.
经常需要在可能被人类免疫缺陷病毒（HIV）污染的粪便中寻找隐孢子虫属的卵囊。为保护处理粪便材料的实验室人员，福尔马林被认为是有用的。然而，当采用糖浓溶液浮选离心技术和“粪便检测”技术进行粪便检查时，尚未对这种消毒剂进行评估。我们的经验表明，使用福尔马林可能会干扰第一种方法的检测结果，但不会改变第二种方法的结果。这一信息对未来的辅助和科学研究具有重要意义。
