Figure 4.

The phylogenetic placement of S. arctica and S. svanai isolated from gray wolves in Lithuania on the basis of 18S rDNA (a), cox1 (b), rpob (c), 28S rDNA (d), and ITS1 (e). Phylogenetic trees were constructed using Maximum Likelihood method, scaled according to branch length and rooted on Toxoplasma gondii. The dashed line points out that its length does not correspond to the evolutionary distance. Figures next to branches display bootstrap support values. Sequences obtained in the present work are highlighted in indigo. Red rectangles show Sarcocystis species using members of order Carnivora as their intermediate hosts. Sarcocystis species employing birds in their life cycle are indicated with purple rectangles and Sarcocystis species cycling between rodents and birds are indicated with green rectangles.
