We describe the characterization of a novel species cultivated from ticks collected in Russia and France, for which we propose the name sp. nov. Using multigene sequencing, we demonstrated that five rickettsial isolates from , , and ticks were classified within this novel spotted fever rickettsia species. This rickettsia also exhibited a serotype distinct from previously described species. The type strain of sp. nov. is strain Khabarovsk (=CSUR R3 =ATCC VR-1596).
