[Serological studies on the occurrence of rickettsial infections in Togo (author's transl)].

The incidence of rickettsioses in Togo was examined by means of the microagglutination-technique according to Giroud. Out of 559 sera obtained from different parts of the country the following percentages of positive reactions were found: R. prowazeki 0.2%, R. mooseri: 4.7%, R. conori: 0.4%, R. burneti: 2.0%. It was proved that 1) R. mooseri-infections were more prevalent in adults than in children and adolescents and 2) R. mooseri-infections were found more frequently in the southern regions of the country, whereas R. burneti-infections were more widely distributed in the north of Togo.
