Analysis Of Pathogen Distribution And Microbial Sensitivity Of Blood Culture In Hospitalized Patients In Department Of Urology From 2009-2012

Objective:To investigate the distribution of pathogens and drug resistance of blood culture in hospitalized patients in the department of urology in order to provide evidence of rational antibiotics choice.Methods:Results of blood culture and microbial sensitivity of hospitalized patients in department of urology at the Affiliated Hospital of Medical College Qingdao University from 2009 to 2012 were analyzed retrospectively.Results:Pathogens were cultured in 87 of 596(14.6%)blood samples,of which 55 strains of gram-negative bacteria,29 strains of gram-positive bacteria and 3 strains of fungus were separated respectively,E.coli was predominant among gram-negative bacteria,and staphylococcus haemolyticus and enterococcus faecalis were the most common gram-positive bacteria.Microbial sensitivity tests demonstrated that E.coli and pseudomonas aeruginosa were resistant to a spate of common antibiotics.There also existed serious drug resistance among gram-positive cocci.No gram-positive cocci were found resistant to vancomycin,teicoplanin and linezolid.Conclusion:Gram-negative bacteria are predominant pathogens causing blood infection in department of urology,of which E.coli accounts for the most common bacterium whose drug resistance becomes more and more severe.The positive rate of pseudomonas aeruginosa is rising year after year.
