Abstract
In part, Cyclospora cayetanensis owes its recognition as an emerging pathogen to the increased use of staining methods for detecting enteric parasites such as Cryptosporidium. First reported in patients in New Guinea in 1977 but thought to be a coccidian parasite of the genus Isospora, C. cayetanensis received little attention until it was again described in 1985 in New York and Peru. In the early 1990s, human infection associated with waterborne transmission of C. cayetanensis was suspected; foodborne transmission was likewise suggested in early studies. The parasite was associated with several disease outbreaks in the United States during 1996 and 1997. This article reviews current knowledge about C. cayetanensis (including its association with waterborne and foodborne transmission), unresolved issues, and research needs.
摘要
卡耶塔环孢子虫被认定为一种新出现的病原体，部分原因是检测隐孢子虫等肠道寄生虫的染色方法使用增多。1977年在新几内亚的患者中首次报道了卡耶塔环孢子虫，但当时认为它是等孢球虫属的一种球虫寄生虫，直到1985年在纽约和秘鲁再次被描述之前，它几乎没有受到关注。在20世纪90年代初，怀疑存在与卡耶塔环孢子虫经水传播相关的人类感染；早期研究同样表明存在经食物传播。1996年和1997年期间，该寄生虫在美国与几起疾病暴发有关。本文综述了关于卡耶塔环孢子虫的现有知识（包括其与经水传播和经食物传播的关联）、未解决的问题以及研究需求。
