Molecular phylogenetic analysis for Rickettsia spp. detected on Senegalese tabanids. The evolutionary history based on the gltA gene was inferred by using the maximum likelihood method based on the Tamura 3-parameter model. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 17 nucleotide sequences. All positions containing gaps and missing data were eliminated. There were a total of 441 positions in the final dataset
