Resumen:
To date, three tick-borne pathogenic Rickettsia species have been reported in different regions of Argentina,namely, R. rickettsii, R. parkeri, and R. massiliae. However, there are no reports available for the presence oftick-borne pathogens from the northeastern region of Argentina. This study evaluated the infection withRickettsia species of Amblyomma dubitatum ticks collected from vegetation and feeding from capybaras(Hydrochoerus hydrochaeris) in northeastern Argentina. From a total of 374 A. dubitatum ticks collected andevaluated by PCR for the presence of rickettsial DNA, 19 were positive for the presence of Rickettsia belliiDNA, two were positive for Rickettsia sp. strain COOPERI, and one was positive for the pathogenic Rickettsiasp. strain Atlantic rainforest. To our knowledge, this study is the first report of the presence of the humanpathogen Rickettsia sp. strain Atlantic rainforest and Rickettsia sp. strain COOPERI in Argentina. Moreover,our findings posit A. dubitatum as a potential vector for this pathogenic strain of Rickettsia.
