The organisms only proliferate if they are inside of a eukaryotic cell.

INFECTIOUS AGENTS. Rickettsial infections are caused by multiple bacteria from the order Rickettsiales and genera Rickettsia, Anaplasma, Ehrlichia, Neorickettsia, Neoehrlichia, and Orientia ( Table 4-19 ). Rickettsia spp. are classically divided into the spotted fever group (SFG) and the typhus group, although more recently these have been classified into as many as 4 groups.
