There has been an explosion of descriptions of new species of Cryptosporidium during the last two decades. This has been accompanied by confusion regarding the criteria for species designation, largely because of the lack of distinct morphologic differences and strict host specificity among Cryptosporidium spp. A review of the biologic species concept, the International Code of Zoological Nomenclature (ICZN), and current practices for Cryptosporidium species designation calls for the establishment of guidelines for naming Cryptosporidium species. All reports of new Cryptosporidium species should include at least four basic components: oocyst morphology, natural host specificity, genetic characterizations, and compliance with the ICZN. Altogether, 13 Cryptosporidium spp. are currently recognized: C. muris, C. andersoni, C. parvum, C. hominis, C. wrairi, C. felis, and C. cannis in mammals; C. baïleyi, C. meleagridis, and C. galli in birds; C. serpentis and C. saurophilum in reptiles; and C. molnari in fish. With the establishment of a framework for naming Cryptosporidium species and the availability of new taxonomic tools, there should be less confusion associated with the taxonomy of the genus Cryptosporidium. The clarification of Cryptosporidium taxonomy is also useful for understanding the biology of Cryptosporidium spp., assessing the public health significance of Cryptosporidium spp. in animals and the environment, characterizing transmission dynamics, and tracking infection and contamination sources.

隐孢子虫分类学：最新进展及其对公共卫生的影响。

在过去的二十年中，对隐孢子虫新物种的描述激增。这伴随着物种命名标准的混乱，这主要是由于隐孢子虫属之间缺乏明显的形态学差异和严格的宿主特异性。对生物学物种概念，国际动物学命名法（ICZN）和隐孢子虫物种命名的当前做法的回顾要求建立隐孢子虫物种命名的指南。所有有关隐孢子虫新物种的报告均应至少包括四个基本组成部分：卵囊形态，天然宿主特异性，遗传特征以及对ICZN的依从性。总共13个隐孢子虫属。目前公认的：C。muris，C。andersoni，C。parvum，C。hominis，C。哺乳动物的wrairi，C。felis和C. cannis；鸟类中的C.baïleyi，C。meleagridis和C. galli；爬行动物中的蛇形弯曲杆菌和嗜酸弯曲杆菌 和鱼中的C. molnari。随着命名隐孢子虫种类的框架的建立和新分类学工具的可用性，与隐孢子虫属的分类学相关的混乱应减少。澄清隐孢子虫的分类学也有助于理解隐孢子虫的生物学，评估隐孢子虫的公共卫生意义。在动物和环境中的传播，表征传播动态，并跟踪感染和污染源。随着命名隐孢子虫种类的框架的建立和新分类学工具的可用性，与隐孢子虫属的分类学相关的混乱应减少。澄清隐孢子虫的分类学也有助于理解隐孢子虫的生物学，评估隐孢子虫的公共卫生意义。在动物和环境中的传播，表征传播动态，并跟踪感染和污染源。随着命名隐孢子虫种类的框架的建立和新分类学工具的可用性，与隐孢子虫属的分类学相关的混乱应减少。澄清隐孢子虫的分类学也有助于理解隐孢子虫的生物学，评估隐孢子虫的公共卫生意义。在动物和环境中的传播，表征传播动态，并跟踪感染和污染源。评估隐孢子虫的公共卫生意义。在动物和环境中的传播，表征传播动态，并跟踪感染和污染源。评估隐孢子虫的公共卫生意义。在动物和环境中的传播，表征传播动态，并跟踪感染和污染源。
