用ＥＬＩＳＡ方法对１９９１年４月至１９９２年４月从省级医院收集的儿科住院病儿３１７例及健康体检儿童８６例进行９种１５型军团菌ＩｇＭ抗体的检测。３５例（１１．０４％）住院病儿诊为军团菌病，呼吸系统疾病患者中有２５例（１１．６８％）、肾脏疾病、血液病有５例（５／１５），其它疾病有１例（１．４５％）为军团菌病患者；２例（２．３３％）健康儿童为军团菌近期感染。病原以Ｔａｔｌｏｃｋｉａｍｉｃｄａｄｅｉ（２０例，４７．６２％）及Ｌｐ＿１６（１０例，２３．８１％）多见，Ｆｌｕｏｒｉｂａｃｔｅｒｂｏｚｅｍａｎａｅ占１４．２９％，其它种型较少见。军团菌病的分布特点是年长儿童发病多，夏季发病比例高，城乡居住者发病比例差别无统计学意义。
Thirty-nine Legionella pneumophila IgM antibodies were detected by ELISA in 317 pediatric inpatients and 86 healthy children collected from provincial hospitals from April 1991 to April 1992. Thirty-five patients (11.04%) were diagnosed with Legionella disease, 25 (11.68%) patients with respiratory diseases, 5 (5/15) patients with renal diseases and blood diseases and 1 Cases (1.45%) were Legionnaires disease patients; 2 cases (2.33%) of healthy children were Legionella recent infections. The most common pathogens were Tatlockiamicdadei (20 cases, 47.62%) and Lp_16 (10 cases, 23.81%). Fluoribacter bozemanae accounted for 14.29%. Other species were rare. The distribution of Legionnaires’ disease is characterized by more incidence of disease in older children, higher incidence of summer disease, and no significant difference in the incidence of urban residents.
