摘要
目的了解列车空调车I刹菌污染状况及相关人员军冈菌感染情况。方法从合肥车辆段徐州区间的客车服务人员中，抽取列车乘务人员和站台售货人员各400名，组成实验组（乘务人员组）和对照组（站台组），做血清军团菌抗体检测；采集的风管积尘样和空调冷凝水样按规范进行军团菌分离培养和鉴定，并以PER方法确证。结果乘务人员组军网菌感染阳性率为53．65％，与站台组阳性率（17．3％）差异有统计学意义（P〈0．01），人群感染军团菌菌型主要为Lp6；列车空调军团菌污染率为19．39％，积尘中车团菌阳性率与冷凝水中阳性率差异有统计学意义（P〈0．01），检出主要菌划为Lp1。结论列车空调风管积尘的采集更具有军团菌流行病学的代表意义，健康人群中可能存在军团菌的机会件感染。
Objective We want to understand the case of Legionella pollution in the train and related personnel Legionella infection. Method Taking the train crew amt station sales staff of 400 from Xuzhou, Hefei depot serviee staff, composed of test and control group, ingenious and to be detected with serum antibody of Legionella. Dust samples and water samples collected from train air- conditioning condensation were treated with acid -heating, then vaccinated in GVPC in isolating and identifying finally , being compared with the site, there are significant differences （P 〈0.01 ）. The main Legionella type people infected was Lp6. The contamination rate of the train air - conditioning was 19.39%, Dust in Legionella -positive rate was far higher than the positive rate of water condensation （P 〈 0. 01 ）, and the main type deteeted in experiment was Lpl. Conclusion Colleeting duet dust is more representative of epideminlogical significance. Legionella opportunistic infections may exist in healthy population.
