Bartonella bacilliformis is the etiologic agent of Carrion's disease, which if endemic to Peru. Studies on antimicrobial resistance genes from clinical isolates of this pathogen are scarce, and the molecular characteristics of these genes and their region resistance-associated are currently unknown. In this work we made the molecular characterization of the quinolone-resistance, and establish the region (QRDR) for the topoisomerase IV, which is encoded by the parC and parE genes, as well as develop an antimicrobial susceptibility test for B. bacilliformis. 65 Blood samples from La Libertad, Cusco, Ancash and Piura were processed on Blood Agar plates and incubated at 30 °C, 5% CO2. The antimicrobial susceptibility was determined, then the genomic DNA extracted, aforementioned genes amplified, their sequence determined and it analyzed using bioinformatics tools. Six positive cultures were...
