Phylogenetic analysis for 28S rRNA using the maximum likelihood method with 1,000 bootstrap replications. Values <50% are not shown. The nucleotide sequences of 28S rRNA detected in this study were contained within Sarcocystis calchasi and formed a separate branch within a group encompassing Sarcocystis spp. obtained from birds as intermediate hosts or definitive hosts. Toxoplasma gondii was included as the outer group. Bootstrap values are shown on the interior branch nodes, and scale bars indicate the number of substitutions per site. Individual Sarcocystis spp. are named as follows: accession number, definitive or intermediate host, and species of Sarcocystis (country). A red circle represents the Sarcocystis spp. identified as LC796270 in this study. rRNA, ribosomal ribonucleic acid.
