Figure S2. Bayesian phylogenetic analysis of all SSU rDNA sequence fragments. Unrooted phylogenetic tree comprised of 317 SSU rDNA sequences (277 G. microti, purple clade; 5 G. duodenalis, green clade; 32 G. muris, blue clade and 3 O. intestinalis, red clade). Reference sequences (GenBank accession numbers) of O. intestinalis, G. muris, G. duodenalis and G. microti are included (uncoloured sequence names). Posterior probabilities ≥ 0.5 are illustrated by black dots (proportionally increasing in size). Sequence names are color coded (colored ranges) according to the rodent host. Further color coding (inner to outer layer) was introduced according to locality [1 to 11: 1 (“Billerbeck”), 2 (“Gotha”), 3 (“Krahnberg”), 4 (“Schaderode”), 5 (“Jeeser”), 6 (“Saal”), 7 (“Kammerforst”), 8 (“Leinawald”), 9 (“Pahnaer Holz”), 10 (“Phönix Ost”), 11 (“Weissach”); see also Additional file 1: Figure S1 and Table 1], season (spring, summer, autumn), habitat (F = “forest”, GL= “grassland”) and year of sample collection (2011, 2012). Maximum likelihood analysis based on PhyML resulted in a similar tree (not shown). (TIFF 2598 kb
