“…Multilocus genotyping of Cryptosporidium spp. associated with diarrhea outbreak in a day care unit by DNA sequencing analysis of fragments coding for 18S, COWP and a microssatelite locus (ML1) revealed the presence of C. hominis in all the 29 samples 4 . Cryptosporidium isolates identified in fourteen stool samples from five HIV patients and nine immunocompetent children revealed two C. parvum, eight C. hominis and two C. meleagridis 1 .…”

“…In Brazil, few studies on the relative frequency of Cryptosporidium genotypes found in humans have been published, with C. parvum and C. hominis being incriminated as the most prevalent genotypes 1,2,3,4,5 . In this paper, we aimed to reveal and discuss the relative frequencies of Cryptosporidium in human patients from an infectious diseases hospital in the municipality of São Paulo, São Paulo State, Brazil.…”

Cryptosporidium spp. are important cause of enteric disease in humans, but may also infect animals. This study describes the relative frequency of several Cryptosporidium species found in human specimens from HIV infected patients in the São Paulo municipality obtained from January to July 2007. Sequence analysis of the products of nested-PCR based on small subunit rRNA and Cryptosporidium oocyst wall protein coding genes revealed 17 (63.0%) isolates of C. hominis, four (14.8%) C. parvum, five (18.5%) C. felis and one (3.7%) C. canis. These findings suggest that, in urban environments of Brazil, the cat adapted C. felis may play a potential role in the zoonotic transmission of cryptosporidiosis whereas the anthroponotic transmission of cryptosporidiosis caused by C. hominis seems to predominate.
