Phylogenetic tree for small subunit ribosomal RNA sequences of Cyclospora and Eimeria species. Quartet puzzling maximum likelihood results are shown, with Toxoplasma gondii as the outgroup. After analysis, the outgroup branch was removed for clarity. Numbers to the left of the nodes indicate the quartet puzzling support for each internal branch. The scale bar indicates an evolutionary distance of 0.01 nucleotides per position in the sequence. Vertical distances are for clarity only. GenBank acce
