| Abstract (English): | This work presents a description of the knowledge on the association between ticks and potentially path ogenic bacterial microorganisms for humans in Argen tina to date. The presence of a potentially pathogenic microorganism in a tick is a necessary but not sufficient condition for transmission, as the vector must possess both competence and vectorial capacity. In Argentina, 44 species of hard ticks (family Ixodidae) have been recorded, among which those belonging to the genera Amblyomma and Rhipicephalus are the most relevant species due to their potential capacity for pathogen transmission, parasitism in humans, and geographic distribution. Among the diseases caused by bacterial pathogens, spotted fever caused by Rickettsia (Rickettsia rickettsii, Rickettsia parkeri, and Rickettsia massiliae) are the only tick-borne diseases with confirmed human cases in Argentina, where Amblyomma sculptum, Ambl yomma tonelliae, Amblyomma triste, Amblyomma tigrinum and Rhipicephalus sanguineus sensu stricto are the vectors involved. Different species and strains of Ehrlichia, in cluding some closely related to Ehrlichia chaffeensis, the agent of human monocytic ehrlichiosis, have been found in ticks parasitizing humans, indicating a potential risk. Finally, based on the currently available evidence, the vectorial capacity of ticks from the genus Ixodes to transmit pathogenic Borrelia spp. from the Lyme disease group to humans in Argentina is extremely low.

| Abstract (Spanish): | En este trabajo se presenta una descripción del esta do del conocimiento sobre la asociación entre garrapatas (Acari Ixodida) y microrganismos bacterianos poten cialmente patógenos para los humanos en Argentina. La presencia de un microorganismo potencialmente patógeno en una garrapata es una condición necesa ria pero no suficiente para la transmisión, porque el vector debe tener competencia y capacidad vectorial. En Argentina se registraron 44 especies de garrapatas duras (familia Ixodidae), de las cuales, por su capacidad potencial de transmisión de patógenos, parasitismo en humanos y distribución geográfica, se destacan aquellas pertenecientes a los géneros Amblyomma y Rhipicephalus. Dentro de las enfermedades causadas por patógenos bacterianos, las fiebres manchadas por Rickettsia (Rickett sia rickettsii, Rickettsia parkeri y Rickettsia massiliae) son las únicas enfermedades transmitidas por garrapatas con casos humanos confirmados para Argentina, donde los vectores involucrados son Amblyomma sculptum, Ambl yomma tonelliae, Amblyomma triste, Amblyomma tigrinum y Rhipicephalus sanguineus sensu stricto. Distintas especies y cepas de Ehrlichia, incluyendo especies estrechamen te relacionadas con Ehrlichia chaffeensis, agente de la ehrlichiosis monocítica humana, han sido halladas en garrapatas que parasitan a humanos, con lo cual hay un potencial riesgo de ocurrencia de casos. Por último, la evidencia actualmente disponible no permite asignarle relevancia epidemiológica a la capacidad vectorial de las garrapatas del género Ixodes para transmitir borrelias del grupo de la enfermedad de Lyme a los humanos en el territorio argentino.
