| 目的 了解北京市大饭店空调冷却塔军团菌污染现况及相关人群感染水平。方法 按分层随机抽样的方法，抽取北京市14家大饭店（四五星级）中央空调38个冷却塔；抽取相应饭店健康工作人员（暴露人群）和非从事饭店行业的健康人群（对照人群）各414人，分别进行军团病的病原学及人群血清学检测。结果 所调查饭店中12家空调冷却塔有军团菌污染，污染率85.7%；有21个冷却塔检出军团菌，阳性率55.3%（21/38）；共分离16株军团菌，均为嗜肺军团菌种，其中8株菌的菌型为血清1型。暴露人群血清中军团菌感染的阳性率9.9%（41/414），对照人群3.5%（14/414），阳性率差异有显著性，暴露人群高于对照人群（χ2=14.2，P＜0.01）。结论 军团菌普遍存生于空调冷却塔，已对暴露人群的健康造成威胁，建议对这一潜在传染源采取有效防范措施。 |

| Objective To understand the situation of Legionella-contamination at cooling towers of big hotel and the level of Legionella-infection among related populations in Beijing. Methods Thirty-eight cooling towers of hotels were chosen for detection of Legionella. Four hundred and fourteen staff members from the hotels were selected as exposure group, with another 414 from general population as controls, for the detection of Legionella antibodies. Results Sixteen strains of Legionella pneumophila (Lp) were isolated from 21 of the 38 cooling towers,and the predominant strain was Lp serum group 1(50%,8/16). The seroprevalence of Lp antibodies for the exposure group was 9.9% (41/414), comparing to 3.5% (14/414) from the control group. The difference was statistically significant(χ2=14.2,P＜0.01). Conclusion Legionella was discovered in air-conditioning cooling tower of the hotels, which threatened the health to the population exposed to it. |
