OBJECTIVE To study the sites of nosocomial infection in the Traditional Chinese Medical Hospital and the pathogen distribution and drug resistance;to provide basis against nosocomial infection. METHODS Retrospective analysis was performed for 851 strains of bacteria isolated from those tested specimens sent by the inpatient department from 2005 to 2007. RESULTS The main sites of nosocomial infection was respiratory tract,followed urinary tract and wounds,the main responsible bacteria was Gram-negative bacilli,their rate was 52%.While the rate of Gram-positive cocci was 36%,the rate of fungi was 12%.The common bacteria in nosocomial infection our hospital were Klebsiella pneumoniae,Escherichia coli,Pseudomonas aeruginosa,Staphylococcus and Candadi albicans,whose rate of drug resistance was similar to that in the comprehensive hospital. CONCLUSIONS In nosocomial infection the proportion of Gram-positive cocci and fungi is increasing,so is their rate of drug resistance.It mustn′t be neglected in clinic.
