采用脉冲场凝胶电泳（PFGE）和基于序列的分型（SBT）技术，对31株与流行病学无关的嗜肺军团菌血清1型分离株（10株来自冷却塔，10株来自公共温泉和/或温泉浴场，11株来自患者）进行了分析，使用6个位点flaA、pilE、asd、mip、mompS和proA。PFGE和SBT分析结果表明，10株冷却塔分离菌聚为一个独特的类型，与其他环境来源的菌株不同。
Thirty-one epidemiologically unrelated Legionella pneumophila serogroup 1 isolates (10 from cooling towers, 10 from public spas and/or hot spring baths, and 11 from patients) were analyzed by pulsed-field gel electrophoresis (PFGE) and sequence-based typing (SBT) using 6 loci,flaA,pilE, asd, mip, mompS, and proA. The results of PFGE and SBT analysis indicated that all 10 isolates from cooling towers clustered into a unique type, which was distinct from strains of other environmental sources.
