The disinfection of cooling towers based on manufacturers' treatment protocols, as employed in units installed at various public gathering places in Dallas, Tex. (hotels, municipal auditorium), and at the city health department, was evaluated for effectiveness in controlling Legionella pneumophila and compared with previous laboratory studies. In specimens collected in September and December, 1978, L. pneumophila was isolated from 2 of 4 specimens from untreated cooling towers, 2 of 4 specimens from towers treated with agents deemed ineffective in earlier laboratory tests, 6 of 11 specimens from towers treated with putatively effective agents, and 0 of 4 specimens from towers treated with an agent unknown efficacy. These results suggest the need for further studies to identify biocidal agents effective in eliminating L. pneumophila from air-conditioning cooling towers.
基于制造商的处理方案,对得克萨斯州达拉斯市各公共聚集场所(酒店、市政礼堂)以及市卫生部门安装的冷却塔进行消毒,评估其在控制嗜肺军团菌方面的有效性,并与之前的实验室研究进行比较。在1978年9月和12月采集的样本中,未处理的冷却塔的4个样本中有2个分离出嗜肺军团菌,早期实验室测试中被认为无效的试剂处理过的冷却塔的4个样本中有2个分离出嗜肺军团菌,据推测有效的试剂处理过的冷却塔的11个样本中有6个分离出嗜肺军团菌,而功效未知的试剂处理过的冷却塔的4个样本中未分离出嗜肺军团菌。这些结果表明需要进一步研究,以确定能有效消除空调冷却塔中嗜肺军团菌的杀菌剂。
