RESUMO
Objective To investigate the distribution and resistance of clinical isolates obtained from the second affiliated hospi-tal of Chongqing medical university in 2012 .Methods The bacteria strains isolated from clinics were collected .Identification and drug susceptibility test were performed by automatic analysis system and API manual identification system .The date was analyzed according with software WHONET 5 .6 .Results A total of 3 454 bacterial isolates were obtained ,which included 36% gram-posi-tive strains ,64% gram-negative strains and 1% Anaerobic bacteria .The detection rates of methicillin-resistant S .aures was 33% , the detection rate of vancomycin -resistant enterococci was 1 .6% .In enterobacteriaceae ,ESBLs producing strains accounted for 60 .6% and 35 .8% in E .coil and K .pneumonia respectively .The drug resistance of A .baumannii and P .aeruginosa was increased . Conclusion Drug resistance of bacterial isolated from our hospital is universal .Drug monitoring data is important for clinical treat-ment .
