Figure. Phylogenetic relationship of 6 rickettsial outer membrane protein B rickettsiae groups (578 bp) identified in Amblyomma maculatum ticks collected in Arkansas and similar rickettsiae identified from GenBank. The tree was constructed by using the maximum-likelihood and maximum-parsimony analysis in BEAST 9 (http://beast.bio.ed.ac.uk/Main_Page) Numbers on lines are bootstrap support values >75 and numbers at nodes are posterior values. Scale bar indicates nucleotide substitutions per site.
