Optimal Neighbour-Joining tree inferred using a 791 bp alignment of the partial Eimeria cytochrome C oxidase I (COI) locus. Evolutionary distances were calculated using the Kimura 2-parameter model. The number of base substitutions per site between sequences are shown to the right of the sequence identifiers, presented as a/b (x), where a = maximum number within a recognised species/Operational Taxonomic Unit (OTU) group, b = minimum between recognised species/OTUs, and the figure in parentheses is the fold difference. Pairwise analyses were conducted using the Maximum Composite Likelihood method. Aus, Australia; Nig, Nigeria.
