Phylogenetic relationships of the ompB (A), ompA (B), and gltA (C) genes of Rickettsiae detected from ticks in Zambia. Phylogenetic analysis was based on 397, 460, and 596 bp of the ompB, ompA, and gltA genes, respectively. Numbers at branch nodes indicate bootstrap values ≥50%. The reference sequences included in the analyses are shown by their GenBank accession number, species, and country of origin. The Rickettsiae characterized in the present study are in red text.
