Figure 2. Genetic relationship among 6 Cryptosporidium ubiquitum subtype families (XIIa–XIIf) in animals as indicated by a neighbor-joining analysis of the partial gp60 geneThe XIIa subtype family contains all specimens from domestic and wild ruminants, whereas the remaining subtype families contain all specimens from rodents and other wildlifeWithin the XIIa subtype family, 1, 2, and 3 denote subtypes 1, 2, and 3, which differ from each other by a few nucleotidesBootstrap values are indicated along branchesScale bar indicates 0.02 nucleotide substitutions per site.
