Phylogenetic relationships among gp60 subtype families of Cryptosporidium ubiquitum. Four polymorphic loci of CP47, cgd6_60, cgd2_3690, and cgd4_370 were selected in constructing trees by a neighbor-joining analysis of nucleotide sequences using distance calculated by the Kimura 2-parameter model. Bootstrap values greater than 50% from 1000 replicates are shown.
