ABSTRACT
Objective To learn drug resistance of bacteria isolated from a hospital of Chengdu from 2012 to 2013 .Methods From 2012 to 2013 ,39 732 clinical specimens were collected ,ATB Express half‐automatic bacteria identification system were used to identify the bacteria ,and paper diffusion(K‐B) method was used to do drug sensitive test ,results were judged according to Clini‐cal and Laboratory Standards Institute 2012 standard interpretation ,Whonet5 .6 was used to do statistical analysis .Results In the bacteria isolated from this hospital in 2012 and 2013 ,gram‐positive bacteria accounted for 27 .7% and 37 .4% respectively ,gram negative bacteria accounted for 72 .3% and 62 .6% .The top five pathogenic bacteria were E .coli(16 .3% ,20 .3% ) ,Pseudomonas aeruginosa(11 .5% ,11 .7% ) ,Staphylococcus aureus (11 .3% ,11 .4% ) ,Acinetobacter baumannii(10 .6% ,9 .3% ) ,Klebsiella pneu‐moniae(14 .7% ,12 .0% ) .The detection rates of Methicillin‐Resistant Staphylococcus(MRSA) were 56 .2% ,47 .7% .The positive rates of producing extended spectrum βlactamases(ESBLs) of E .coli and Klebsiella pneumonia accounted for 41 .0% ,32 .2% and 21 .0% ,10 .8% ,which were high sensitive to carbon penicillium alkene antibiotics and amikacin .Susceptibility monitoring results showed that the drug resistance of Acinetobacter baumannii was rising ,and the drug resistant of Pseudomonas aeruginosa to most antibiotic were decline .Conclusion The top five bacteria isolated from this hospital in 2012 and 2013 are given priority to gram‐negative bacteria ,in addition to the drug resistant trend of Acinetobacter baumannii increased slightly ,the drug resistant of other four common bacteria were decline .Clinical attention should focus on positive ESBLs ,E .coli ,Klebsiella pneumoniae ,MRSA and M ulti‐resistant bacteria .
