Acinetobacter baumannii is a nosocomial pathogen whose presence has increased in intensive care units due to its mechanisms of antibiotic resistance. In the latest bulletin on the epidemiological situation of infections associated with health care (IAAS) published by the CDC in the first half of 2021, A. baumannii was placed as the main cause of nosocomial infections, being the causal pathogen of 32.07% of nosocomial pneumonia cases and 24.92% of bloodstream infections. However, this bulletin does not contain information on the resistance rates of emerging bacteria in hospitals in our country. For this reason, the objective of this study was to evaluate the antibiotic resistance of 47 strains of A. baumannii isolated from patients from the Hospital Regional Docente de Cajamarca in Cajamarca, Peru during 2018. The antibiotic resistance of the strains was determined following the standards of the Clinical and Laboratory Standards Institute (CLSI) using disc diffusion method on Mueller-Hinton agar plates for ampicillin-sulbactam, piperacillin-tazobactam, cefotaxime, ceftazidime, cefepime, gentamicin, amikacin, levofloxacin, doxycycline, tetracycline, meropenem, imipenem, trimethoprim-sulfamethoxazole and using the minimum inhibitory concentration method for colistin. The rates of resistance to ceftazidime, cefotaxime, imipenem and meropenem were 100%; 97.87% to piperacillin-tazobactam, gentamicin and trimethoprim/sulfamethoxazole; 91.49% to levofloxacin; 68.09% to amikacin; 59.57% to cefepime; 48.94% to tetracycline; 44.68% to ampicillin/sulbactam; 36.17% to doxycycline and 4.08% to colistin. All strains were resistant to at least one antibiotic agent. One strain (2.13%) proved to be resistant to all antibiotics tested and was classified as potentially pan-drug resistant (PDR). 24 isolates (51.06%) were classified as extensively resistant (XDR), presenting susceptibility to colistin in all cases. The remaining 22 isolates (46.81%) were considered as multi-drug resistant (MDR).
