FIG. 2.
Genetic relationship among named Cryptosporidium species and unnamed genotypes inferred by a neighbor-joining analysis of the partial SSU rRNA gene. Values on branches are percent bootstrapping using 1,000 replicates. Numbers following species or genotypes are isolate identifications used in the construction of the phylogenetic tree, whereas numbers in parentheses are the number of isolates sequenced. Modified from reference 255.
