Cryptosporidium muris infection in an HIV-infected adult, Kenya

We describe a case of Cryptosporidium muris infection in an HIV-infected adult with diarrhea in Kenya. Sequence analysis of an 840-bp region of the 18S rRNA gene locus demonstrated the isolate had 100% nucleotide identity with C. muris recovered from a rock hyrax, 98.8% with a C. muris calf isolate, 95.5% with C. serpentis, but only 87.8% with C. parvum human type.
