Title: Analysis on clinical distribution and resistance characteristic of Acinetobacter baumannii isolated clinically from 2008-2012
Abstract: Objective To investigate the clinical distribution and resistance characteristic trend of Acinetobacter baumannii in Huashan Hospital isolated clinically from January 2008 to September 2012,and to provide the reference for clinical rational using of antimicrobial agents. Methods The drug-resistance of Acinetobacter baumannii and resistance characteristic trend to common antimicrobial agents were analyzed by disk agar diffusion method. Results In the past 5 years,the detection rate of clinical isolated Acinetobacter baumannii from sputum specimens was highest,and mainly distributed in neurosurgery department and intensive care unit. The isolation rate in neurosurgery department presented obvious increasing trend from 19. 6% in 2008 to 35. 3% in 2012. The resistance of clinical isolated Acinetobacter baumannii was serious,and carbapenem antimicrobial agents had the obvious increasing trend. The resistance rate of imipenem rase from 57. 5% in 2008 to 71. 2% in 2012,the resistance rate of meropenem rase from 56. 8% in 2008 to 71. 7% in 2012,and the resistance rates of other lactams,cephalosporins,aminoglycosides and fluoroquinolones were 70. 0%-80. 0%. Conclusions The infection of Acinetobacter baumannii is serious in mainly neurosurgery department and intensive care unit. The clinical isolates are commonly resistant to all kinds of antimicrobial agents,and carbapenem antimicrobial agents present a obvious increasing trend. Monitoring the resistance of Acinetobacter baumannii should be strengthened for preventing resistant bacteria from spreading.
