Genetic diversity of Dermacentor reticulatus: (a) phylogeny of Dermacentor spp. based on ITS-2. The evolutionary history was inferred by using the maximum-likelihood method and the Tamura 3-parameter model. The analysis contains sequences identified in the current study (marked with blue dot) and GenBank sequences. Accession numbers of sequences and country of origin are given. Bootstrap values are represented as percentage of internal branches (1,000 replicates), and values lower than 60 are hidden. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. Rhipicephalus microplus sequence KX450289 was used to root the tree; H—haplotype. (b) Geographical distribution of D. reticulatus haplotypes based on sequence analysis ITS-2 obtained in the current study and sequences available in GenBank. (c) Network analysis of geographical distribution of D. reticulatus haplotypes based on analysis of ITS-2 sequence obtained in the current study and sequences available in GenBank. The diagonal lines indicate the number of mutations between haplotypes.
