Figure 4

Maximum likelihood trees inferred from Baylisascaris sp. mitochondrial and ribosomal gene sequences. A: ML of concatenated mitochondrial markers CO1 and CO2 shows a clear separation between B. procyonis and B. columnaris, which in turn is divided into two different groups. B: ML of concatenated ribosomal markers ITS1-5.8S-ITS2 and 28S again shows two B. columnaris groups, which separate from B. procyonis, although to a lesser extent, due to the number of G-A repeats (9, 7 and 6) as most important difference (see also Table 4).
