Abstract

Six Cryptosporidium spp. were found in 50 of 179 Milwaukee wastewater samples collected weekly over a year. Of the eight subtypes of Cryptosporidium hominis and Cryptosporidium parvum present, allele Ib was found in 14 of 16 samples, and its sequence was identical to that of the subtype in human samples from the 1993 Milwaukee outbreak of cryptosporidiosis.

Relationship among C. parvum and C. hominis subtypes inferred by neighbor-joining analysis of GP60 nucleotide sequences. The Kimura two-parameter model was used in distance calculation. Numbers on branches are percent bootstrap values from 1,000 resamplings.
