DOI: 10.1016/j.ttbdis.2020.101470
Abstract: Rickettsial pathogens cause diseases that vary in severity and clinical presentation. Rickettsia species transmitted by ticks are mostly classified within the spotted fever group of rickettsiae (SFGR) and are often associated with febrile diseases. Preliminary… read more here.
