多重耐药肺炎克雷伯菌的分析

目的 了解某地区多重耐药肺炎克雷伯茵的特点,为临床治疗及控制医院感染提供理论依据.方法 用K-B法进行常规药敏试验,筛选出多重耐药肺炎克雷伯菌,用确认试验检测超广谱B-内酰胺酶(ES-BLs),同时以头孢西丁三相试验检测以上菌株产AmpC酶情况.结果 107株多重耐药肺炎克雷伯菌中单一检出产ESBLs 53株(49.5%),产AmpC酶30株(28.0%),同时产ESBLs和AmpC酶24株(22.4%).它们对氨基苷类、喹诺酮类及头孢菌素类药物表现出较高的耐药性.结论 某地区多重耐药肺炎克雷伯菌产酶率较高,主要产ESBLs和AmpC酶,应加强其耐药性监测,合理选用抗生素,减缓多重耐药菌株的产生.

Analysis of the multi-resistance to antibiotics of clinical isolated klebsiella pneumoniae

Objective To investigate the multi-resistance to antibiotics of clinical isolated klebsiella pneumoniae.Methods The resistance to antibiotics of clinical isolated klebsiella pneumoniae were monitored.The discconfirmatory test was used to detect extended-spectrum β-lactamases(ESBLs) and cefoxitin three-dimension was used to detect AmpC β-lactamases.Results Among the isolates there were 53 strains of ESBLs-producing bacteria (49.5% ), 30 strains of AmpC-producing bacteria(28.0%), 24 strains of ESBLs + AmpC-producing bacteria (22.46%).They were high resistance to aminoglycosides,quinolones and cephalosporins.Conclusion The multi-resistance to antibiotics of clinical isolated klebsiella pneumoniae were widespread.It is important to control nosocomial infection to strengthen the detection of the epidemiology of ESBLs and AmpC β-lactamases in clinical isolates.
