Abstract:
Objective To explore the distribution of Acinetobacter baumannii and its drug resistance to 17 antimicro-bial agents to provide basis for clinical treatment.Methods The data of 689 strains of A.baumannii from Jan.2010 to Dec. 2012 were collected and reviewed for bacterial identification and drug sensitive test and then analyzed using WHONET 5.4. Results 689 strains of A.baumannii isolates were broadly distributed in sputum (75.5%), most primarily isolated from the ICU (36.9%).The antimicrobial susceptibility testing showed that the drug resistance rate of Ab was the highest to Bactrim (36.3%), followed by gentamicin (29.0%), and the lowest to cefperazone-sulbactam (8.0%).The drug resistance rate of Ab to cefperazone-sulbactam was the lowest (8.5%) in 2012.In the three years, the drug resistance rate of Ab to imipenem was the biggest rise (14.5%);while to gatifloxacin and levofloxacin declined.The drug resistance rate of Ab to gatifloxacin dropped by 13.1%, which was bigger than that to levofloxacin (9.5%).The drug resistance rates of Ab to the rest antimi-crobial agents fluctuated insignificantly, but were all in an increasing trend.Conclusion Acinetobacter baummannii mainly distribute in sputum of patients in the ICU and department of respiratory diseases, and its detection rate and drug resistance rate are increasing year by year.
