Nucleotide sequences of the Cryptosporidium oocyst wall protein (COWP) gene were obtained from various Cryptosporidium spp. (C. wrairi, C. felis, C. meleagridis, C. baileyi, C. andersoni, C. muris, and C. serpentis) and C. parvum genotypes (human, bovine, monkey, marsupial, ferret, mouse, pig, and dog). Significant diversity was observed among species and genotypes in the primer and target regions of a popular diagnostic PCR. These results provide useful information for COWP-based molecular differentiation of Cryptosporidium spp. and genotypes.
隐孢子虫卵囊壁蛋白(COWP)基因的核苷酸序列取自多种隐孢子虫物种(怀氏隐孢子虫、猫隐孢子虫、火鸡隐孢子虫、贝利隐孢子虫、安氏隐孢子虫、鼠隐孢子虫和蛇隐孢子虫)以及微小隐孢子虫的不同基因型(人、牛、猴、有袋动物、雪貂、小鼠、猪和犬)。在一种常用诊断性聚合酶链反应(PCR)的引物和靶区域中,观察到不同物种和基因型之间存在显著差异。这些结果为基于COWP的隐孢子虫物种和基因型的分子鉴别提供了有用信息。
