چکیده
We report the first laboratory-confirmed case of Rickettsia mongolotimonae infection in Africa. The patient sought treatment for an eschar on his toe; lymphangitis, severe headaches, and fever subsequently developed. After a regimen of doxycycline, symptoms rapidly resolved. R. mongolotimonae infection was diagnosed retrospectively by serologic tests and molecular-based detection of the organism in biopsy specimens of eschar material.

متن کاملDetection and identification of spotted fever group Rickettsiae and Ehrlichiae in African ticks.
Rickettsia africae, a recently identified pathogen, was detected for the first time in Amblyomma ticks from Niger, Mali, Burundi, and Sudan, and "R. mongolotimonae" was identified for the first time in Africa. Rickettsiae of unknown pathogenicity and two new ehrlichiae of the Ehrlichia canis group were identified in ticks from Mali and Niger.

Rickettsia conorii, a spotted fever group rickettsia which is transmitted by Rhipicephalus sp. complex ticks, was considered until now the only pathogenic rickettsia prevalent in Greece. Here, we report the presence of "Rickettsia mongolotimonae" (proposed name) detected simultaneously in a patient and in a Hyalomma anatolicum excavatum tick, sampled on the patient.
