Evaluation of Dermacentor species naturally infected with Rickettsia raoultii

In the present study, we investigated the efficiency of transovarial transmission and intensity of multiplication of three R. raoultii genotypes in four naturally-infected Dermacentor species. We used the method of experimental modelling of a natural cycle of the metamorphosis of vectors (MEMNCMv) that allows the study of the role of tick species as vectors of infectious agents, including rickettsiae.
