鲍曼不动杆菌广泛分布于自然界和医院环境中,能在潮湿和干燥的表面生存,也可存在于健康人的皮肤和上呼吸道,为条件致病菌。但近年来鲍曼不动杆菌已成为医院感染的重要病原菌,在非发酵菌中,其临床标本分离率仅次于铜绿假单胞菌。由于高度的多重耐药性或泛耐药性,鲍曼不动杆菌 Acinetobacter baumannii widely distributed in nature and the hospital environment, can survive on wet and dry surfaces, but also can exist in healthy human skin and upper respiratory tract, as the opportunistic pathogens. However, in recent years, Acinetobacter baumannii has become an important pathogen of nosocomial infections. In non-fermentative bacteria, the clinical sample isolation rate is second only to that of Pseudomonas aeruginosa. Acinetobacter baumannii due to its high degree of multidrug resistance or pan-drug resistance
