Title: Distribution and drug resistance of acinetobacter baumannii from 2008 to 2009
Abstract: OBJECTIVE To analyze the distribution and drug resistance of Acinetobacter baumannii from 2008 to 2009,provide the basis for clinical antibiotics application.METHODS The A.baumannii strains isolated from clinical samples were collected,the identification and antimicrobial susceptibility test were determined by Microscan automatic of microorganism identification and antimicrobial susceptibility testing system,some susceptibility tests adopt the Kirby-Bauer method,the data was analyzed by WHONET 5 sofeware.RESULTS The isolating rate of A.baumannii was 5.33% in 2008,the isolating rate of A.baumannii was 10.41% in 2009,(P0.05).Sputum was the main specimen sources,and ICU was the main endemic area.In 2008,the drug resistance rate of cefoperazone/sulbactam,meropenem and imipenem was below of 5.00%,the drug resistance rate of other drugs exceeded 25.00%,and presented multidrug-resistance.In 2009,the resistance rate of the isolates was significantly exceeded those of isolates in 2008,(P0.05).The drug resistance rate to imipenem was 52.81%,the drug resistance rate of meropenem was 40.55%,the drug resistance rate of cefoperazone/sulbactam was 38.53%,the drug resistance rate of other drugs exceeded 50.00%,and presented severe multidrug-resistance.The rate of PDR-ABA was 2.94% in 2008,and the rate of PDR-ABA was 30.16%,(P0.05).CONCLUSION The isolated rate and drug resistant rate of A.baumannii present obviously ascendant tendency,and the rate of PDR-ABA was 30.16% in 2009.The situation is very severe,every department of hospital should pay more attentions to the problems.
