Abstract:
OBJECTIVE To analyze the antimicrobial resistance of Acinetobacter baumannii.METHODS A.baumannii was collected in our hospital from Jan 2003 to Dec 2006.Antimicrobial susceptibility testing was performed by disk-diffusion method.RESULTS A total of 548 A.baumannii were collected during 4 years.Of these isolates,130(23.7%) strains were from intensive care unit(ICU),190 strains(34.7%)from surgical,and others from medical and emergency departments.Most of strains(78.5%) were isolated from sputum,next from wound.The prevalence of A.baumannii was increasing during last 4 years.Results of susceptibility test showed that imipenem was the most active antibiotic against A.baumannii.The resistance rates were high to most antibiotics.Most of the resistant strains was from the ICU and the general ward differentand had significant difference.More than 50% of isolates were resistant to all antimicrobial agents tested except imipenem and ciprofloxacin in ICU.CONCLUSIONS The prevalence of A.baumannii is increasing.A.baumannii isolates show high resistance to multiple antibiotics,especially in ICU.
