Abstract

Highlights: Ticks from a Spotted Fever endemic region in North Argentina were analysed by PCR. DNA of Candidatus "Rickettsia amblyommii" was found. Amblyomma hadanii (21.3%) and A. neumannii (44%) were positive. DNA of Rickettsia rickettsii was not found. All A. sculptum and Haemaphysalis juxtakochi resulted negative to PCR analyses. Abstract: Ticks from an endemic Spotted Fever region in Argentina were analysed by PCR for Spotted Fever Group Rickettsiae. DNA of " Candidatus Rickettsia amblyommii" was found in 21.3% of Amblyomma hadanii and in 44.0% of A. neumanni . Amblyomma sculptum (formerly A. cajennense ) and Haemaphysalis juxtakochi were negative for rickettsial DNA. DNA of Rickettsia rickettsii, the etiological agent of the clinical cases reported within the studied region was not detected in the analysed sample.
