鲍曼不动杆菌感染分布及耐药性分析

Analysis of infection distribution and drug resistance of Acinetobacter Baumannii

目的 了解我院鲍曼不动杆菌的感染分布与耐药情况,为临床治疗提供依据.方法 对住院患者送检样本中培养分离出的329株鲍曼不动杆菌的感染分布与耐药情况进行分析.采用稀释法进行药物敏感试验,结果按美国临床实验室标准化协会判定.结果 鲍曼不动杆菌主要分布在重症监护病房（神经科监护病房和ICU,分别为81株和66株）和呼吸内科（64株）,主要来自痰标本（298株90.6%）,对丁胺卡那霉素的耐药率最低（16.28%）,其次为亚胺培南（31.25%）,对其他19种抗菌药物的耐药率均较高.结论 鲍曼不动杆菌主要引起呼吸道感染,对现有多种抗菌药物耐药严重,提示临床医生必须对该菌所致感染予以高度重视,关注易感人群,加强对该菌的监测,合理使用抗菌药物,以提高疗效和减缓耐药菌株的产生.

Objective To investigate the clinical distribution and dmg resistance of Acinetobacter baumannii and to offer basis for the clinical therapeutics.Methods Analyze the infection distilbution and drug resistance of 329 samples of Acinetobacter baumannii that were isolated from various kinds of specimens from inpatients.The drug sensitivity test was done by means of dilution and the results were assessed with Clinical and Laboratory Standards Institute（CLSI）.Results Acinetobacter baumannii samples were mainly distributed in intensive care unit （ICU） ward and Respiration department.The highest positive rate of Acinetobacter baumannii was in sputum（90.6%）.The resistance rates to Amikacin（16.28%）were the lowest.Acinetobacter baumannii Was high resistant to Other 19 tested antibiotics.Condusions Acinetobacter baumannii is a common pathogen of respiratory tract infection,which has a high resistance rate to the current clinical antibacterial agents.Consequently.clinical doctors should consider the infection results from Acinetobacter baumannii to increase the positive effect and reduce drug resistance rate.
