Introduction: The increase in the prevalence of multidrug-resistant Acinetobacter baumannii infections in hospital settings has rapidly emerged worldwide as a serious health problem.
Methods: This review synthetizes the epidemiology of multidrug-resistant A. baumannii, highlighting resistance mechanisms.
Conclusions: Understanding the genetic mechanisms of resistance as well as the associated risk factors is critical to develop and implement adequate measures to control and prevent acquisition of nosocomial infections, especially in an intensive care unit setting.
