Epidemiological studies of Rickettsia felis and related bacteria are very important, because the natural cycle of this important infection has not yet been established. The recent emergence of R. felis-associated febrile diseases in West and East Africa demands insightful epidemiological studies of the vectors and reservoirs of this bacterium in Africa. Twenty-nine cat fleas, Ctenocephalides felis, were tested for the presence of rickettsiae, including R. felis, bartonellae, and borreliae, with specific quantitative real-time PCR assays. Supporting our previous studies, R. felis was not detected in the fleas collected. In addition, neither Bartonella nor Borrelia was found. In five (17%) examined fleas, we found another species of rickettsia. We isolated three rickettsial strains, and genetic analysis demonstrated that these strains represent a probable new species, provisionally called Candidatus Rickettsia senegalensis here.
