The phylogenetic relationships of the identified Rickettsia species. Analysis of the gltA partial gene based on Bayesian inference (model GTR + G + I, 2,000,000 generations). Our own isolates are marked with a black circle. Rac indicates sequences previously obtained from raccoons and available in GenBank
