Abstract:
Objective To analyze drug resistance of pathogenic bacteria from the blood culture and distribution in clinical departments,and to guide the rational clinical drug use.Methods We retrospectively analyzed 11 275 samples of blood cultures in The Central Hospital of Wuhan from 2012 to 2014.The blood specimens were cultured by VersaTREK(USA).The pathogenic bacteria were identified and their drug resistance was analyzed by BD-PHOENIX 100 automicrobiological identification systems(USA).Results Among the 11 275 blood cultures,636 bacterial strains were detected.The top four bacterial strains were Escherichia coli,Staphylococcus aureus,Klebsiella pneumonia and Enterococcus f aecium.A vancomycin-resistant Enterococcus faecium strain and a pandrug-resistant Klebsiella pneumoniae strain were detected.The top three clinical departments with distribution of pathogens were Gastroenterology Department,Nephrology Department and Intensive Care Unit (ICU).Pathogens isolated from ICU were evenly distributed.Conclusion Distributions of pathogenic bacteria in the blood culture are different in clinical departments.Identification of pathogenic bacteria and result of drug susceptibility can reduce use of broadspectrum antimicrobials and enhance antimicrobial de-escalation.
