Analysis of the infection and drug resistance of pathogenic bacteric in venous catheter / 国际检验医学杂志

ABSTRACT

Objective To investigate the hospital distribution and drug resistance of pathogens of venous catheter-related infec-tion,so as to provide basis for appropriate usage of antibiotics in clinic.Methods The culture and drug susceptibility results of 369 venous catheter were analyzed retrospectively from 2009 January to 2012 December.Results 161 strains of pathogens were detec-ted among 369 venous catheter,the positive rate was 43.6%.There were 83 strains of Gram positive bacteria,accounting for 51.6%,and Staphylococcus epidermidis had the highest positive rate.There were 63 strains of Gram negative bacteria,accounting for 39.1%,and Klebsiella pneumoniae and Bauman Acinetobacter were main isolated bacteria.There were 15 strains of Fungi,ac-counting for 9.3%,and Candida parapsilosis had the highest positive rate.There was none Gram positive bacteria resistant to van-comycin and linezolid.Carbapenems remained high activity against Gram negative bacteria.Conclusion Staphylococcus epidermidis and Klebsiella pneumoniae are mainly detected in venous catheter in the hospital infection.
