Phylogenetic tree based on 322 partial sequences of cox1 of 61 taxa, including the seven Sarcocystis species (types 1–7) from this study and inferred using the neighbour-joining method and with evolutionary distances computed using the p-distance method. Bootstrap support (1000 replicates) is shown at each node. Subtrees formed by two or more haplotypes of the same species have been collapsed. The number of haplotypes included is given in parentheses. The number of sequences of each Sarcocystis species used in this analysis and their GenBank accession numbers are shown in Table S3.
