本文报告了１９９０年１１月～１９９１年１１月重庆地区２６１例发热待查病人嗜肺军团菌Ⅰ型（ＬｅｇｉｏｎｌｉａｐｕｅｕｍｏｐｈｉｌａＬＰ１）感染研究。作者采用ＥＬＩＳＡ法测定其血清抗体效价水平。结果表明，血清抗休效价阳性有９５例，占总例数的３６％。其中抗体效价＜１：４０有６７例（７０．５％），＞１：８０有１６例（１６．８％），＞１：３２０有１２例（１２．６％）。在１２人达到诊断标准（１：３２０）的病人中，有９人年龄在５０岁以上、３人在５０发以下。还用直接荧光免疫法对１９例患者痰及支气管灌洗液作了ＬＰ１型抗原测定。结果表明，２名患者支气管灌洗液ＬＰ１抗原阳性。１名患者痰抗原阳性。本研究为临床军团菌感染的诊断和治疗提供了可靠依据。
This article reports the infection of LegionellapueumophilaLP1 in 261 patients with pyretic fever in Chongqing from November 1990 to November 1991. The authors used ELISA method to measure the serum antibody titers. The results showed that serum anti-titers were 95 positive cases, accounting for 36% of the total number of cases. Among them, 67 (70.5%) were antibody titers <1:40, 16 (16.8%) were> 1:80 and 12 (12.6%) were> 1: 320. Of the 12 patients who reached the diagnostic criteria (1: 320), nine were over 50 years of age and three were under 50. Direct immunofluorescence assay was also performed on LP1 antigen in sputum and bronchial lavage fluid of 19 patients. The results showed that two patients with LP1 antigen bronchial lavage positive. One patient had sputum antigen positive. This study provides a reliable basis for the diagnosis and treatment of clinical Legionella infection.
