Fig. 3From: Range-wide genetic analysis of Dermacentor variabilis and its Francisella-like endosymbionts demonstrates phylogeographic concordance between both taxaPhylogenetic relationships among 257 geographically diverse Francisella-like endosymbiont sequences from the USA and Canada. A maximum parsimony bacterial 16S rRNA tree is given, illustrating a distinct genetic split within the endosymbiont population, which mirrors that of the tick hostBack to article page
