Rickettsia parkeri Infection

Rickettsia parkeri is as an emerging agent of tick-borne rickettsiosis in the Americas. More than 60 years after its initial isolation from tick vectors it was recognised as a human pathogen. Dogs have been characterised as sentinels for human rickettsiosis in rural areas in Brazil, Bolivia and Uruguay, by sharing the same tick species infesting humans and dogs (Labruna et al., 2007; Venzal et al., 2008; Tomassone et al., 2010).
