Using DNA sequencing and phylogenetic analysis, we identified four distinct Cryptosporidium genotypes in HIV-infected patients: genotype 1 (human), genotype 2 (bovine) Cryptosporidium parvum, a genotype identical to C. felis, and one identical to a Cryptosporidium sp. isolate from a dog. This is the first identification of human infection with the latter two genotypes.
通过DNA测序和系统发育分析,我们在HIV感染患者中鉴定出四种不同的隐孢子虫基因型:基因型1(人源)、基因型2(牛源)微小隐孢子虫、一种与猫隐孢子虫相同的基因型,以及一种与从狗身上分离出的隐孢子虫属菌株相同的基因型。这是首次鉴定出人类感染后两种基因型。
