, a newly recognized tick-borne pathogen of humans in the Americas, is a confirmed cause of spotted fever group rickettsiosis in Argentina. Until recently, almost all cases of rickettsiosis in Argentina have originated from the Paraná River Delta, where entomological surveys have identified populations of -infected ticks. In this report, we describe confirmed cases of rickettsiosis from Córdoba and La Rioja provinces, which are located several hundred kilometers inland, and in a more arid ecological region, where ticks do not occur. Additionally, we identified questing ticks naturally infected with in Córdoba province. These data provide evidence that another human-biting tick species serves as a potential vector of in Argentina and possibly, other countries of South America.
