Figure. Phylogenetic tree inferred from outer membrane protein ompB region (600 bp) showing 4 separate branches of Rickettsia spp. in ticks. The sequences we obtained (bold) were placed into highly supported subclade corresponding with R. raoultii. First sequence (haplotype 1) shows 100% identity with GenBank accession no. DQ365797 from D. reticulatus ticks from France. Second sequence (haplotype 2) has 100% identity with GenBank accession no. HQ232262 from D. reticulatus ticks from Germany. The numbers at the nodes show posterior probabilities under the Bayesian inference/bootstrap values for maximum likelihood. GenBank accession number are provided for reference sequences. Branch lengths indicate expected numbers of substitutions per nucleotide site.
