摘要

In this study, we genotyped parasites from the fecal specimens of sporadic cryptosporidiosis cases in Brit-ish Columbia from 1995 to 1999. Genotyping was conducted by polymerase chain amplification of theinternal transcribed spacer region, a hypervariable region in the 18S rRNA gene and the Cryptosporidiumoocyst wall protein gene. Subsequent analysis was by restriction fragment length polymorphism and DNAsequencing. We identified two new Cryptosporidium genotypes in humans. One of these genotypes hasbeen found recently in deer in New York state. The other genotype has not been identified in humans oranimals. These results have important implications for drinking water quality strategies, especially for com-munities that obtain drinking water supplies from surface sources located in forested regions with deerpopulations
