Abstract:
Objective:To study the detecting rate of nonfermenters and their resistance to the antibiotics in nosocomial infections in our hospital. Methods:The bacteria were identified by VITEK-AMS, the susceptibility tests(K-B method) were done according to the NCCLS standard and the results were analyzed. Results: The detecting rate of nonfermenters was 14. 29%. The most common bacterium was P. aeruginosa (the component ratio was 44. 22%). followed by A. baumannnii (32. 17%) and S.maltophilia(9.23%). The infectious rates of nonfermenters were different at different infectious sites, with the highest rate in the respiratory system and the lowest in central nervous system. The resistant rate to the antibiotics of P. aeruginosa was 45. 21% ,of A. baumannnii 47. 85% and of S. maltophilia 64. 02%. Conclusion:The detecting rate of nonfermenters is rather high in the nosocomial infection in our hospital. Due to the high resistant rates of nonfermenters to the antibiotics , the drugs should be chosen accoding to the result of the drugs susceptibility test.
