Phylogenetic analysis of the microorganisms found in ectoparasites. Neighbor-joining trees were based on the fragments of the gltA and 16S rRNA genes of the microorganisms found in the ectoparasites and rodents described in this study. Sequences were aligned and analysed as described in the Methods section. The number of sequenced isolates is between brackets. Small triangles indicate less than 1% variation. Only bootstrap values >75 are indicated. The Bartonella-related sp. found in ~ 10% of the questing ticks is indicated in the gltA-tree as "? Ca. Midichloria mitochondrii".
