Figure. Phylogenetic relationships between 3 unusual Cryptosporidium genotypes and known Cryptosporidium species/genotypes as inferred by a neighbor-joining analysis of the small subunit rRNA gene. Evolutionary distances were calculated by the Kimura 2-parameter model with Eimeria tenella as an outgroup. Bootstrapping values >50% from 1,000 pseudoreplicates are shown at branches.
