Clinical and Epidemiological Studies on Rickettsial Infections in Ethiopia.
Abstract
The evidence overwhelmingly suggests that only Rattus and its ectoparasites are involved in the ecology of murine typhus in Ethiopia. Native murines such as Mastomys, Praomys, etc., entering or living in houses do not seem to play a role in the absence of Rattus even though they may be infested with the presumed vector fleas. Non-commensal rodents were free of demonstrable Rickettsia mooseri infection even in the case of murines living in fields just a few yards from where infected Rattus were found in houses. Xenopsylla cheopis fleas were present wherever infected Rattus were found, but were uncommon. A high rate of infection with R. mooseri was demonstrated in those fleas, as well as in other fleas infesting rats, such as Leptopsylla segnis. Additional evidence was obtained indicating that tick typhus is a widespread infection in Ethiopia.
