The results of the study of the prevalence of SFG rickettsiae in the Odessa region using PCR-RT are presented. For detection of SFG rickettsiae, including R. conorii, there were investigated 3352 specimens ixodes ticks of 6 species — I. ricinus, D. reticulatus, D. marginatus, H. рlumbeum, Rh. sanquineus, Rp. rossicus, collected in the South region during the 2010–2012. A significant spread of SFG rickettsiae into new territory, expansion of the species range of carriers and availability of polivektor foci are revealed. The results indicate the need for further implementation of comprehensive ecological and epidemiological research in order to obtain qualitative and quantitative characteristics of natural foci rickettsiae infections in Ukraine to improve epidemic measures and reduce risk population.
