The genus Acinetobacter comprises several groups of closely related species(1, 2), including the Acinetobacter calcoaceticus-baumannii complex that was initially proposed in 1991(3). At that time, it had not yet been described what would become one of the most important multidrug-resistant pathogen, Acinetobacter baumannii(4). In the following decades, A. baumannii became one of the most prevalent and well adapted pathogen to the nosocomial environment(5). This adaptive ability is probably a consequence of its evolutionary exposure to selective pressure of antimicrobials, over a long period, in the complex and competitive environment(4, 5).Read more . . .
