绿脓杆菌分布甚广,土壤、污水、空气、正常人体表以及与外界相通的腔道中都可存在。一般认为系条件致病菌,在抵抗力降低时可导致感染,因此多见于医院内交叉感染,尤以烧伤病房的感染更为严重;又因其有天然耐药性,对大多数常用抗菌素不敏感,给治疗带来一定困难,目前已引起普遍重视。近年来对于绿脓杆菌的结构及其与致病免疫之间的关系又有了新的认识。现就绿脓杆菌引起感染的情况、细菌的致病性、机 Pseudomonas aeruginosa distribution is very wide, soil, sewage, air, normal human body surface and the same channel with the outside world can exist. Generally believed that the conditions of pathogenic bacteria, can reduce the resistance to lead to infection, so more common in the hospital cross-infection, especially in ward infection more serious; because of its natural resistance, the most commonly used antibiotics do not Sensitive to the treatment of certain difficulties, has caused widespread attention. In recent years, there has been a new understanding of the structure of Pseudomonas aeruginosa and its relationship with pathogenic immunity. Pseudomonas aeruginosa is now caused by the infection, the pathogenic bacteria, machine
