Abstract
Objective To analyze the pathogenic bacteria distribution and drug resistance of blood infection. Methods A total of 560 cases with positive blood culture results were included in the study. Species of the bacteria were identified with VITEK 2 compact. Antimicrobial susceptibility testing was conducted with disk diffusion ( KB method) . Testing results were interpreted using 2010 CLSI Standards for Antimicrobial Susceptibility Testing. Drug resistance was analyzed using WHONET 5. 6 software. Results The isolated 568 strains consisted of Gram - negative bacilli (386/568, 68. 0% ) , Gram - positive bacilli (165/568, 29. 0% ) , and fungi ( 17/568, 3. 0% ) . Escherichia coli had the highest isolation rate of 34. 9% ( 198/568) , followed by Klebsiella pneumoniae 16. 9% (96/568 ) . Coagulase negative staphylococcus had the highest isolation rate of 15. 5% (88/568) among Staphylococcus, followed by Staphylococcus aureus 9.0% (51/568). Escherichia coli and Klebsiella pneumoniae Vere 100% sensitive to carbopenems, while exhibited varied resistance to other drugs. Staphylococcus was 100% sensitive to vancomycin . Conclusion The bacteria causing blood infection are mainly Gram - negative bacilli. Escherichia coli are the major pathogenic bacteria. The infection of Coagulase negative staphylococcus should be treated with caution.关键词
