Abstract

The success of Acinetobacter baumannii as an emerging organism is probably linked to its high resistance to adverse environmental conditions. This study was conducted to analyze the association between some factors that may favor the dissemination of A. baumannii clinical isolates. A total of 47 clinical strains of A. baumannii were evaluated to carbapenem, the ability to produce biofilm, the susceptibility to some antiseptics, and the survival time on cotton fabrics. Most of the isolates were resistant to carbapenem (72.3%), produced biofilm (83%), and survived more than 7 (51%) days on fabrics. A significant association between decreased susceptibility to antiseptics containing chlorhexidine or triclosan and carbapenem resistance and survival on fabrics could be observed. The resistance to carbapenem was significantly associated with survival on fabric, but not with the ability to form biofilm. The survival of the isolates on fabric was not associated with the ability to produce biofilms. Characteristics, such as resistance to antibiotics, ability to form biofilm, and survival on dry surfaces, probably contribute to the proliferation of this organism when selected in the hospital environment and can partly explain its success as responsible for nosocomial infection.
