Fig. 2From: Molecular and serological evidence of flea-associated typhus group and spotted fever group rickettsial infections in MadagascarMaximum likelihood phylogeny of Rickettsia species detected in fleas from Tsiroanomandidy based on ompB gene. Phylogenetic analysis was performed with 801Ā bp and 795 fragment of ompB gene of R. felis and R. typhi, respectively, with GTRā+āG as the best DNA substitution model. Bootstrap valuesā>ā80% are presented. The scale bar on the bottom of the tree represents the number of substitutions per site.
