Abstract:
Objective To study the distribution of pathogens,the positive time and drug resistance of pathogenic bacteria by blood culture of adult patients,in order to provide the basis for the early clinical discovery and treatment of bacteremia. Methods 3 537 specimens of adult blood culture were collected from July 2016 to December 2016,then identified the posi-tive bacteria strains,and analysed the antimicrobial susceptibility.Results In 3 537 specimens of adult blood culture,485 positive samples were detected,and the positive rate was 13.7%(485/3 537).Including 203 cases(41.9%)of both aerobic and anaerobic positive bottles,220 cases(45.3%)of aerobic positive bottles,and 62 cases(12.8%)of anaerobic positive bottles.About pathogens,229 specimens were gram-negative bacteria strains,accounting for 47.2%.The great majority of bacteria was E.Coli,Klebsiella pneumoniae,Pseudomonas aeruginosa,and they all showed sensitivity to imipenem.202 specimens were gram-positive bacteria strains,accounting for 41.7%,mainly on Staphylococcus aureus and Staphylococcus epidermidis,they all showed sensitive to vancomycin.54 strains were Fungi,accounting for 11.1%.For analysis of 203 ca-ses of aerobic and anaerobic both positive bottles,the results showed that:there were 121 cases of gram-negative bacteria strains,95(78.5%)specimens anaerobic jar to positive time earlier than aerobic bottle to positive time,26(21.5%)speci-mens aerobic bottle jar to positive time earlier than anaerobic bottles to positive time.78 cases of gram positive bacteria,an-aerobic jar to earlier than aerobic bottle to positive time had 45 strains,accounting for 57.7%.Aerobic bottle to positive time earlier than anaerobic bottles to positive time had 33 strains,accounting for 42.3%.Fungi,a total of 4 strains,50% each. Positive pathogens were mainly distributed in I,emergency surgery,respiratory medicine department.Conclusion Pathogen-ic bacteria isolated from the adult blood culture was given priority to gram-negative bacteria,pathogenic bacteria species and drug susceptibility difference was obviously.Clinicians should be combined with blood culture and drug susceptibility results of use of antimicrobial drugs to patients.
