Abstract

OBJECTIVE To investigate the clinical distribution and resistance of Acinetobacter baumannii.METHODS The bacteria were identified by BioMerieux VITEK32.Susceptibility was tested by Kirby-Bauer method.RESULTS Among specimens from which A.baumannii was examined,sputum accounted for 78.64%,secretion(9.62%)and urine(6.81%).A.baumannii was mainly distributed at ICU ward(29.58%)and then was respiratory ward(21.36%).The resistance of A.baumannii was serious.The antibiotic drugs which had the low resistance were β-lactam/β-lactamase inhibitor combinations such as sulperazone(22.14%)and carbapenems such as meropenem(32.95%),imipenem(33.04%),and so on.CONCLUSIONS The infecton of multi-drug resistant A.baumannii has increasing tendency.Therefore monitoring A.baumannii constantly and regularly,finding out resistant strains timely and adjusting the treatment methods are very important for the prevention of nosocomial infection.
