鲍曼不动杆菌是医院感染重要条件致病菌。近年来,鲍曼不动杆菌感染日益增多,仅次于金黄色葡萄球菌和大肠埃希菌,并且呈现多重耐药现象,已引起临床医生和微生物工作者的高度关注。鲍曼不动杆菌耐药机制包括染色体基因突变,外膜孔蛋白改变,药物主动外排系统和产生灭活酶等。细菌 Acinetobacter baumannii is an important condition of nosocomial infection pathogens. In recent years, Acinetobacter baumannii infection is increasing, second only to Staphylococcus aureus and Escherichia coli, and the phenomenon of multi-drug resistance has attracted great attention of clinicians and microbiological workers.
