HART CASARES, Marcia et al. Study of the antimicrobial sensitivity of Acinetobacter baumanii in "Hermanos Ameijeiras" Hospital, year 2006. Rev cubana med [online]. 2008, vol.47, n.3, pp. 0-0. ISSN 1561-302X.

Acinetobacter baumanii is a microorganism that is acquiring a great relevance as a nosocomial pathogen. It has developed a great increase of antimicrobial resitance that makes difficult to find an effective drug capable of covering all the severe infections it produces, leading to therapeutical failure in many cases. That is why we carried out a characterization study of Acinetobacter baumanii strains, isolated from patients admitted to determine their sensitivity level to a wide range of antibiotics. The diagnostic tests were performed using API system, with ID 32 GTN and ATB GN 5 galleries. There were identified 72 strains, which showed high levels of resistance against the assayed antibiotics. More than 65% percent of resistance to b-lactamics was obtained. The less active antibiotics within this group were Amoxicillin, Ticarcillin, Piperacillin, Cefotaxime, and Cefuroxime, with 100% de resistance in all the cases. Cyprofloxacine, the only quinolone tested, showed 100% of resistance. Among the aminoglycosides, Amikacin was the most effective antimicrobial agent, and that with the lowest resistance. The carbapenemics, imipenem and meropenem had also high values of resistance (52.8% and 55.2%, respectively).

Palabras clave : Acinetobacter baumannii; antimicrobial resistance.
