Figure 1
A consensus phylogenetic tree showing the position of Occidentia massiliensis strain OS18T relative to other strains within the family Rickettsiaceae , based on 16S rDNA sequence comparison. GenBank accession numbers are indicated in parentheses. Sequences were aligned using CLUSTALW, and phylogenetic inferences obtained using the Bayesian phylogenetic analysis [10] with the TOPALi 2.5 software (Biomathematics and Statistics Scotland, Edinburgh, UK) within the integrated MrBayes application [11], using the HKY85 + Г substitution model. Numbers at the nodes are percentages of bootstrap values from 100 replicates. Anaplasma ovis was used as the outgroup. The scale bar represents a 5% nucleotide sequence divergence.
