Resumen

ABARCA, Katia  y  OTEO, José A. Clinical approach and main tick-borne rickettsiosis present in Latin America. Rev. chil. infectol. [online]. 2014, vol.31, n.5, pp.569-576. ISSN 0716-1018.  http://dx.doi.org/10.4067/S0716-10182014000500009.

Tick-borne rickettsial diseases are potentially life threatening infections that in Latin America have an emerging and reemerging character. Until few years ago, Rickettsia rickettsia was the only tick-borne rickettsia present in America; but nowadays several other species such as R. parkeri and R. massiliae are causing disease in humans in the region. In addition, new species are being described; although their pathogenicity has not been confirmed they should be considered as potential pathogens. Since the microbiological diagnosis of rickettsioses can take days or weeks, a high clinical suspicion and early start of appropriate treatment are crucial. In this review the distribution and main clinical manifestations of tick-borne rickettsial diseases in Latin America are detailed. Since R. felis has been found in ticks and the role of this vector has not been clarified, we have included a section about this pathogen.

Palabras clave : Rickettsioses; Latin America; ticks; spotted fever; Rickettsia rickettsii; Rickettsia parkeri; Rickettsia massiliae; Rickettsia felis.
