目的了解成都地区军团菌感染的种型分布特点和优势种型。方法采用微量凝集试验对272份健康人及肺部感染病人血清标本进行LP1~LP8型及LM型军团菌抗体效价测定。结果所测军团菌各种型均有阳性检出,同时感染2~3种血清型者占10.82%。健康人群军团菌抗体阳性率为31.60%(73/231),肺部感染病人为34.14%(14/41)。健康人LP1型阳性率最高(17.31%),其次为LP6型(11.26%),LP8型最低(0.43%)。肺部感染病人LM阳性率最高(9.76%),其次为LP3(7.32%)。结论成都地区普遍存在不同种型的军团菌感染。
Objective To understand the species distribution and dominant species of Legionella infection in Chengdu. Methods Serum samples from 272 healthy individuals and patients with pulmonary infection were assayed for antibody titer with LP1-LP8 and LM-type by microagglutination test. Results All kinds of genus Legionella were detected positive, while infected with 2 to 3 serotypes accounted for 10.82%. Legionella antibodies were 31.60% (73/231) in healthy subjects and 34.14% (14/41) in patients with pulmonary infection. The positive rate of LP1 was highest in healthy subjects (17.31%), followed by LP6 (11.26%) and LP8 (0.43%). The positive rate of LM was the highest in patients with pulmonary infection (9.76%), followed by LP3 (7.32%). Conclusion There are different types of Legionella infection in Chengdu.
