Cryptosporidium parvum is usually considered to be the pathogen responsible for human cryptosporidiosis. We genotyped in 132 stool specimens from 80 Peruvian children, representing 85 infection episodes, using techniques that differentiate species and C. genotypes. Five types of were identified: (67), bovine (8), dog (2) genotypes, meleagridis (7), felis (1). Twenty-five (29%) episodes associated with diarrhea. There was no significant difference age, antecedent stunting, percentage diarrhea, or duration diarrhea genotype, compared those zoonotic Cryptosporidium. Duration oocyst shedding longer genotype than (mean, 13.9 days 6.4 days, respectively; P=.004). Serum samples 8 children meleagridis, felis, tested anti-human immunodeficiency virus (HIV) type 1 antibodies; all found negative. Contrary common belief, novel genotypes can infect HIV-negative children.
