Maximum likelihood for DNA phylograms of selected Sarcocystidae and Coccidia. a The cox1 tree was constructed based on an alignment of partial cox1 gene sequences from eight Polish Sarcocystis tenella isolates and available cox1 gene sequences of related species deposited in the GenBank (a total of 375 sequences). b The ssu rRNA tree was constructed based on an alignment of nearly complete ssu rRNA gene sequences from eight Polish S. tenella isolates and available ssu rRNA gene sequences of related species deposited in the GenBank (a total 184 sequences). The trees were rooted with Eimeria spp. The values between the branches represent percent bootstrap value per 1000 replicates. Bootstrap values below 50 % are not shown. Polish isolates are marked in red. The GenBank accession numbers of all sequences used for construction of the trees are given in Table S1
