A total of 53 engorged adult ticks belonging to the species () ( = 9), ( = 27), ( = 9), ( = 5), and ( = 3), were removed from oryx in Botswana (South Africa). They were tested for the presence of spotted fever group (SFG) and using polymerase chain reaction (PCR). Seventy-seven percent of as well as twenty percent of were positive for , and 16S rRNA SFG PCR assays. All nucleotide sequences were homologous to , the agent of African tick-bite fever (ATBF). None of the tested ticks was positive for 16S rRNA PCR assays. These results suggest for the first time that ticks may be reservoirs of , and support the ATBF risk in this area.
