Abstract:
OBJECTIVE To evaluate the commonly encountered pathogens and drng resistance of bacteria causing secondary infection in patients with malignant tumors and provide reference for clinical antimicrobial usage.METHODS Statistical analysis was made retrospectively in the classification and antimicrobial susceptibility testing in 1 204 strains of pathogens isolated from clinical samples of hospitalized patients with malignant tumors from Jan 2003 to Oct 2005.RESULTS Among 1 204 strains,Gram-positive strains accounted for 31.1%;Gram-negative ones accounted for 52.8%;and fungi accounted for 16.1%.The principal strains were Candida albicans,Escherichia coli,Staphylococcus aureus,Klebsiella pneumoniae,and Pseudomonas aeruginosa.The most frequent infection sites were in respiratory tract,urinary tract and skin-soft tissue.Multiple drug resistant rate of Gram-positive and Gram-negative strains had a tendency of elevation.CONCLUSIONS To reduce the coming of drug resistant strains,etiologic examination should be done in treatment of infectious diseases and antimicrobial therapy should be decided according to the results of susceptibility.
