Abstract:
OBJECTIVE To characterize the pathogenic distribution and drug resistance of nosocomial infection occurred in tumor hospital and therefore provide the information in rational administration of antibiotics to tumor patients complicated with infection.METHODS Flora cultivation and isolation were operated with the methods described by the National Clinical Laboratory Operational Regulations.Flora was identified with the VITEK-32 automatic identifier,and bacteria-susceptibility test was operated with Kirby-Bauer method.RESULTS Totally 1280 strains of pathogenic bacteria were isolated;they comprised 874 strains of G-bacteria and 416 strains of G+ bacteria.In this study,the isolation rates of Pseudomonas aeruginosa,Escherichia coli,Acinetobacter,Enterobacteriaceae and Klebsiella were 14.92%,14.92%,14.06%,13.91% and 10.47%,respectively;whereas that of Streptococcus Group D and Staphylococcus aureus were 24.06% and 7.70%,respectively.Both E.coli and S.aureus were much resistant to antimicrobial agents tested;while imipenem and vancomycin might be chosen for the G-and G+bacteria infection.CONCLUSIONS The bacterial spectrum and their drug-resistance characteristics in the tumor hospital are quite similar to that encountered in general hospitals.So the information on nosocomial infection control from the latter is of great importance in directing on and carrying out the same job in tumor hospital.
