目前,“肺部感染”的含义,除包括常见的急慢性肺部炎症外,还涉及某些因免疫机制障碍所致的肺支气管感染。过去对此课题的研究,多偏重于细菌(或病毒)方面,仅致力于致病菌鉴定,抗菌药物敏感度测定等.随着肺免疫学的研究进展,近年来,国外学者对于一些反复发作的慢性肺部感染的免疫学基础,给予较多的重视,并提出了某些新的综合征。肺部感染的发生进入呼吸道深部的细菌的转归,与病原菌的毒力、全身及局部的防御机能紧密相关。是否引起肺部感染,可有下列三种情况.
At present, the meaning of “pulmonary infection”, in addition to the common acute and chronic lung inflammation, involves certain lung-bronchial infections due to the immunological mechanism. In the past, the researches on this topic mostly focused on bacteria (or viruses), and only focused on the identification of pathogenic bacteria and the determination of antimicrobial susceptibility.With the progress of lung immunology, in recent years, The immunological basis of chronic lung infections is given more emphasis and presents some new syndromes. The incidence of pulmonary infection into the respiratory tract of bacteria in the return of the pathogenic bacteria and virulence, systemic and local defensive function are closely related. Whether to cause lung infection, the following three conditions.
