Phylogenetic trees of selected members of Sarcocystis species. The trees were conducted using 18S rDNA (a), 28S rDNA (b) and mcox1 (c) sequences using maximum likelihood (ML) with the Kimura 2–parameter, Hasegawa–Kishino–Yano and Hasegawa–Kishino–Yano models, respectively. The values between the branches represent bootstrap values per 1000 replicates. Values < 50% are not shown. Besnoitia besnoiti, Cystoisopora suis, Toxoplasam gondii or Hammondia heydorni were selected to root these trees. The newly obtained sequences of the 18S rDNA (OP480004), 28S rDNA (OP480005) and mtcox1 (OP485287) for Sarcocystis platyrhynchosi n. sp. are shown in bold. The phylogenetic trees inferred from the three genes had similar topologies, and Sarocystis platyrhynchosi formed a separate branch within a group encompassing Sarcocystis spp. obtained from avian or carnivorous intermediate hosts and avian marsupial, or carnivorous definitive hosts
