Fig 2. A phylogenetic tree constructed using the maximum likelihood method based on the 16S rRNA sequences of the genus Coxiella.

Fig 2

Coxiella-like endosymbiont sequences analyzed in this study are marked by arrows. C. burnetii group is outlined within clade A. Four clades of the genus Coxiella are labeled A to D. The accession numbers of other sequences from GenBank are shown with the sequence names and countries. The numbers on the branches indicate bootstrap support (1,000 replicates). Scale bar shows the phylogenetic distance between sequences equivalent to 0.02 nucleotide substitutions per site. CLE = Coxiella-like endosymbionts.
