Figure 2. Phylogenetic analyses of rickettsiae based on gltA (A), 17 kDa (B) and ompA (C). Based on analyses in Modeltest 3.06, the models of substitution chosen for analysis in Treepuzzle 5.0 were TrN+G for gltA and 17kDa, and HKY+G for ompA. GenBank accession numbers for each sequence, including those found in this study (IrITA1-3), are shown adjacent to each strain. Numbers near each node represent quartet puzzling support values. Scale bars represent number of inferred substitutions at each site.
