OBJECTIVE To analyze the pathogenic distribution and antimicrobial resistance in our hospital in 2006 and provide the rational information to use antibiotics reasonably. 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 967 strains of pathogenic bacteria were isolated; they comprised 326 strains of Gram- positive bacteria, 541 strains of Gram-negative bacteria and 100 strains of fungi. The main Gram-positive microorganisms included Staphylococcus aureus and Enterococcus faecalis, et al. The main Gram-negative microorganisms included Escherichia coli , Klebsiella pneumoniae , Acinetobacter baumannii , Stenotrophomonas maltophilia and Pseudomonas aerugiinosa, et al. Specimen samples mainly isolated from sputum (43.85%), urine (22.34%), and secretion (10.03%). G^+ microorganisms were sensitive to nitrofurantoin and vancomycin. G^- microorganisms except A. baumannii and S. maltophilia were sensitive to cefoxitin, piperacillin/tazobactam, imipenem, and amikacin; the average resistant rates of A. baumannii and S. maltophilia to antibiotics were 68.20% and 64. 43%, respectively. CONCLUSIONS The severe degree of bacterial multi-drug resistance is increasing, it is urgent to carry out surveillance of bacterial resistance for reasonabe use of antibiotics and decreasing the morbidity rate and the fatality rate. |
