Description
Summary:: To determine the trends of antimicrobial resistance for Acinetobacter baumannii complex isolates recovered from inpatients over a 4-year follow-up survey. : A total of 659 A baumannii complex isolates were recovered from hospitalized patients in Porto Alegre and its metropolitan area, Southern Brazil, from 2017 to 2020. Susceptibility profile was determined for ampicillin/sulbactam, amikacin, gentamicin, imipenem, meropenem, minocycline, polymyxin B and tigecycline. : Overall, PMB was the most active agent against the set of A baumannii isolates over the period. Although stable, a high resistance rate was observed. : Our results shown the presence of an extensively-drug resistant A baumannii complex isolates over the past four years. Polymyxin B has been the only antimicrobial agent that remain with a good in vitro activity. Strict surveillance and infection control measures are mandatory.
