【摘要】 目的了解临床分离嗜麦芽寡养单胞菌对常用抗菌药物的耐药性,为临床合理用药提供依据。方法琼脂稀释法或纸片扩散法测定48株嗜麦芽寡养单胞菌对7种抗菌药物的敏感性。结果嗜麦芽寡养单胞菌对替卡西林/克拉维酸的耐药率最低(12.5%),其次为米诺环素(25.0%)和复方新诺明(31.3%);其余抗菌药物耐药率均≥50.0%,对头孢他啶、头孢他啶/舒巴坦、氯霉素、左氧氟沙星的耐药率分别为62.5%、52.1%、52.1%、50.0%。结论嗜麦芽寡养单胞菌对替卡西林/克拉维酸、米诺环素、复方新诺明较敏感,对其他抗菌药物耐药情况严重,临床上应加强检测和监测。更多还原

【Abstract】 OBJECTIVE To investigate the resistance in clinical isolates of Stenotrophomonas maltophilia to antimicrobial agents. METHODS Susceptibility of 48 S. maltophilia isolates were tested by agar dilution or K-B method. RESULTS The lowest resistance rate of isolates to the antimicrobial agents was to ticarcillin/clavulanic acid (12.5%),then to minocycline (25.0%) and trimethoprim/sulfamethoxazole (31.3%). The resistance rate to ceftazidime,ceftazidime/sulbactam,levofloxacin,and chloramphenicol was 62.5%,52.1%,52.1%,and 50.0%,respectively. CONCLUSIONS Most of S. maltophilia isolates are susceptible to ticarcillin/clavulanic acid,minocycline,trimethoprim/sulfamethoxazole and resistant to other antimicrobial agents. More mornitoring should be enhanced.更多还原
