ABSTRACT
Objective To investigate the variations of tendency of drug-resistance from Jan 2006 to Dec 2008. the origin and the distributing of Acinetobacter baumannii and provide basis for selection of clinical drugs.Methods The characteriztion and sensitivity to antibiotics of Acinetobacter baumannii were analysed using VTTEK-32 system.Results 107 strains of Acinetobacter baumannii were separated and characterized during the three years.The rates of resistance to antibiotics were Imipenem 0.9%,Amikacin 5.6%,Ampicillin/Sulbactam 6.5%,Ampicillin 74.8% Ceftriaone 63.6%,Cefotaxime 38.3%,Aztreonam 25.2%.The resistance rate of Acinetobacter baumanii increased from 2006 to 2008,showed increasing tendency.Conclusion Acinetobacter baumannii showed good sensitivity to Carbapenems,Aminoglycosides,β-lactam antibiotics,Acinetobacter baumanii are widely distributing in hospital and are widely resistant to many kinds of antibiotics,The results suggested that the resistance of Acinetobacter baumannii to antibiotics should be continuously monitored,it will be beneficial for infection-control to collect antibiotics basing on the results of drug-sensitive test.
