自1978年军团菌正式命名以来,目前军团菌属已分离出39个种、61个血清型。我们于1997年11月在成都市两星级宾馆冷却塔循环水分离到2株军团菌(编号为97004、97008),经送请中国预防医学科学院流行病学微生物学研究所鉴定,确认为嗜肺军团菌血清1型(Lp1)。两阳性标本在双抗BCYE培养基上第5天长出单个菌落,菌落直径1～2mm、灰白色、圆形、凸起、湿润、有光泽。该菌为革兰氏阴性杆菌,BCYE-Cys培养基和普通琼脂经10天培养不生长。两株菌具有相同的生长性状:具动力,氧化酶、过氧化氢酶试验均阳性,明胶酶弱阳性,能分解淀粉,不发酵葡萄糖、乳糖、麦芽糖、蔗糖,尿素酶阴
Since Legionella was officially named in 1978, at present, Legionella has isolated 39 species and 61 serotypes. We in November 1997 in Chengdu two-star hotel cooling tower circulating water isolated two strains of Legionella (No. 97004,97008), sent to the Chinese Academy of Preventive Medicine Institute of Epidemiology and Microbiology identified identified as addicted to Legionella pneumophila serotype 1 (Lp1). Two positive specimens grew double colonies on Day 5 of double-stranded BCYE medium. The colony was 1 ~ 2mm in diameter and was gray, round, convex, moist and shiny. The strain is Gram-negative bacilli, BCYE-Cys medium and ordinary agar culture did not grow after 10 days. The two strains had the same growth traits: motile, positive for oxidase and catalase, weakly positive for gelatinase, able to decompose starch, unfermented glucose, lactose, maltose, sucrose, urease
