ABSTRACT
Objective To investigate the distribution and drug resistance of pathogens isolated from blood culture samples from January 2012 to October 2013 to provide the basis for clinical lection of antibacterial drugs.Methods The blood samples were col-lected from the patients with suspected blood infection and cultured by the BD BACTEC 9120 automatic blood culture instrument. The samples with positive results were performed the bacterial identification and the drug sensitivity test by using the VITEK-2 COMPACT automatic bacterial identification instrument.Results A total of 969 strains of pathogens were isolated from blood cul-ture samples,including 540 strains(55.7%)of Gram-positive bacteria,413 strains(42.6%)of Gram-negative bacteria and 16 strains (1.7%)of fungi.The top 3 isolated pathogenic bacteria were Staphylococcus epidermidis,Escherichia coli and Staphylococcus au-reus.Staphylococcus epidermidis and Staphylococcus aureus were highly resistant to penicillin,sensitive to vancomycin and linezol-id;Escherichia coli and Klebsiella pneumoniae were highly sensitive to imipenem and Piperacillin/tazobactam.Conclusion It is nec-essary to understand the blood culture results timely so as to provide the basis for clinical antibacterial therapy and the improvement of the cure rate.
