321株非发酵革兰阴性杆菌耐药性报道

目的了解医院感染常见非发酵革兰阴性杆菌的分布和耐药情况。方法常规方法进行细菌培养及鉴定,Kirby-Bauer法检测非发酵革兰阴性杆菌对12种抗菌药物的药敏结果,2001年版NCCLS标准判断。结果321株菌中铜绿假单胞菌占53.9%;不动杆菌属占17.4%,嗜麦芽寡养单胞菌占12.5%,3种主要非发酵革兰阴性杆菌共占83.8%;铜绿假单胞菌耐药率为28.3%~87.3%,耐药率低的抗菌药物是亚胺培南、哌拉西林、阿米卡星、头孢他啶;不动杆菌属耐药率为14.3%~78.5%,耐药率较低的抗菌药物是亚胺培南、环丙沙星、哌拉西林;嗜麦芽寡养单胞菌耐药率为37.5%~82.5%,耐药率低的抗菌药物是头孢他啶,其他均存在较高耐药率。结论铜绿假单胞菌、不动杆菌属、嗜麦芽寡养单胞菌是引起医院感染的主要非发酵革兰阴性杆菌,对多种抗菌药物存在高耐药率,是临床面临的严峻问题,应加强监测。

Antimicrobial Resistance Report of 321 Strains of Nonfermenters Gram-negative Bacilli

OBJECTIVE To investigate the distribution and the antimicrobial resistance of nonfermenters Gram-negative bacilli causing nosocomial infection.METHODS Routine method was used to isolate and identify,antibiotics susceptibility was tested by the Kirby-Bauer on the NCCLS criterion of 2001.RESULTS Among 321 strains nonfermenters Gram-negative bacilli,Pseudomonas aeruginoa was 53.9%,Acinetobacter were 17.4%,and Stenotrophomonas maltophilia was 12.5%,Three kinds added up to 83.8%.CONCLUSIONS P.aeruginosea,Acinetobacter and S.maltophilia are important nonfermenters Gram-negative bacilli causing nosocomial infection and their drug resistant rate is very high.The matter is horrible in clinics,we should enforce monitoring.
