老年住院患者151株阴沟肠杆菌的分布及耐药性分析

Distribution and drug resistance of 151 strains of Enterobacter cloacae isolated from elder inpatients

目的探讨老年住院患者分离阴沟肠杆菌的临床分布和耐药状况。方法对2009年-2011年间老年住院患者标本中分离的151株阴沟肠杆菌进行耐药性分析。结果 151株阴沟肠杆菌主要来源是痰液(53.6%)和分泌物(24.5%)。敏感率较高的依次为美罗培南、亚胺培南和阿米卡星;对其余抗菌药物均呈现不同程度耐药。结论老年住院患者标本中分离的阴沟肠杆菌耐药情况日趋严重,应根据药敏结果选择抗菌药物。

Objective To investigate the distribution and drug resistance of 151 strains of Enterobacter cloacae isolated from elder inpatients. Methods The drug resistance of 151 strains of Enterobacter cloacae was examined, which was isolated from 151 elder inpatients from the year 2009 to 2011. Results The main sources of 151 stains of Enterobacter cloacae were sputum（53.6%） and secretions（24. 5 %）. The drugs, to which Enterobacter cloacae was highly sensitive, were meropenem, imipenem and amikacin. Enterobacter cloacae showed a drug resistance to the other antibiotics in different degrees. Conclusion That Enterobacter cloacae showes drug resistance to antibiotics is getting serious day by day. Attention should be paled to selecting the antimicrobial based on the results of antimicrobial susceptibility.
