New cryptosporidium genotypes in HIV-infected persons

Emerg Infect Dis. 1999 May-Jun;5(3):444-9. doi: 10.3201/eid0503.990318.

Abstract

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.
