Resumen:
This study was conducted to detect Borrelia burgdorferi sensu lato infection in ixodid ticks from thePatagonia region in the south of Argentina. Therefore, ticks were collected on rodents in the provinces of Chubut, Río Negro and Santa Cruz. These ticks were identified as nymphs of Ixodes cf. neuquenensis andIxodes sigelos. The B. burgdorferi s.l. infection was tested by a battery of PCR methods targeting the geneflagellin (fla) and the rrfA-rrlB intergenic spacer region (IGS). Three pools of I. sigelos nymphs from Chubutand Santa Cruz provinces as well as one pool of I. cf. neuquenensis nymphs from Río Negro province weretested positive in the fla-PCR. The samples of I. sigelos were also positive for the IGS-PCR. Phylogenetically,the haplotypes found in the positive ticks belong to the B. burgdorferi s.l. complex, and they were closelyrelated to Borrelia chilensis, a genospecies isolated from Ixodes stilesi in Chile. The pathogenic relevanceof the Borrelia genospecies detected in both I. neuquenensis and I. sigelos is unknown.
