Susceptibility analysis of clinical separation Escherichia coli from 2007 to 2010

Objective To investigate the susceptibility of Escherichia coli isolated from clinical,and to provide reference for clinical therapy.Methods The susceptibility(MIC) of 1 163 Escherichia coli strains from clinical by broth microdilution test.Results 1163 strains Escherichia coli,402 strains isolated from urine(Accounted for 34.57%),228 strains isolated from blood(Accounted for 19.60%),197 strains isolated from sputum(Accounted for 16.94%).The sensitive rate of ECL to Imipenem,amikacin and Piperacillin/ Tazobactam were about 96.8%,90.9% and 95.3%.The sensitive rate of amoxicillin/ Clavulanate,cefoxitin,ceftazidime,Ticarcilin/ Clavulanate were about 70%-90%,the sensitive rate of Azactam was about 54.4%,and the sensitive rate of others was down 50%.Conclusion The drug susceptibility of E.coli which causes systemic and wound infection is different.The available therapy project should be selected based on the resistance character.
