为了解肺炎病人中军团菌感染状况及其临床和流行病学特点,1992年1～12月,我们在部分健康人群军团菌血清抗体水平调查的基础上,对驻地医院收治住院肺炎病人进行了嗜肺性军团菌(Lp)1-14型和米克达德军团菌(Lm)血清学调查。结果如下。1 材料和方法 1.1 血清标本来源采自中国建筑第八工程局职工医院临床确诊的现患肺炎病人,同时搜集临床资料。 1.2 检测方法用微量凝集试验(MAT)检测血清抗体,操作与结果判定按文献。抗体滴度≥1:16判为抗体阳性;滴度≥1:32,并有肺炎症状及X-线胸片证实,确诊为军团菌感染。Lp-14型菌体抗原和Lm菌体抗原及阳性对照血清均由中国预防医学科学
To understand the status of Legionella pneumonia in pneumonia patients and its clinical and epidemiological characteristics, from January to December 1992, on the basis of surveys of the serum levels of Legionella antibodies in some healthy subjects, we conducted a series of surveys on hospitalized pneumonia patients Serological investigation of Legionella pneumophila (Lp) 1-14 and Legionella pneumophila (Lm). The result is as follows. 1 Materials and methods 1.1 The source of serum samples were collected from patients with pneumonia who were clinically diagnosed at the Workers’ Hospital of Eighth Engineering Bureau of China Construction at the same time to collect clinical data. 1.2 Detection of micro-agglutination test (MAT) serum antibody, the operation and the results of judgment according to the literature. Antibody titers ≥1: 16 were judged as antibody positive; titers ≥1: 32, with pneumonia symptoms and X-ray confirmed. Legionella infection was confirmed.
