We have identified for the first time , and the ticks that harbored them, in Kenya. A total of 5,325 ticks were collected from vegetation, livestock, and wild animals during two field trips to southwestern Kenya. Most were immature forms (85.2%) belonging to the genera or . The adults also included representatives from the genus . Ticks were assessed for rickettsial DNA by a polymerase chain reaction (PCR) using primers for the spotted fever group (SFG)–specific rickettsial outer membrane protein A () gene, and positive amplicons were sequenced. While none of the immature ticks tested positive by PCR, 15.8% of the adult and less than 1% of the spp. were SFG positive. Sequences of amplified products were identified as . These findings extend the known range of .
