本文论述了1996年4月至2000年11月在日本东部东京地区的各种人造环境沃茨中军团菌的出现情况，包括漩涡浴池、冷却塔和其他。共检测了2，895个可能存在军团菌的水样本，其中904个（31%）被证明是阳性的。在各种水源中，军团菌检出率最高的是漩涡浴池和冷却塔，检出率分别为48%和46%。更准确地说，军团菌在私人使用的漩涡浴池中的发生率高于公共使用的漩涡浴池;即，在私人住宅中的浴池中，阳性率为71%，在公司俱乐部住宅中为63%，在公司员工宿舍中为62%，在老人院中为51%。另一方面，军团菌的发生率较低（<或= 30%），公共用途的沐浴，如那些安装在酒店和温泉设施。L的分类嗜肺菌血清群显示，SG 5（34%）在漩涡浴沃茨中占优势，其次是SG 3（22%），而SG 1（32%）主要在冷却塔沃茨中发现。
The present paper deals with the occurrence of Legionella bacteria in a variety of man-made environmental waters, including whirlpool bathes, cooling towers and others, from April 1996 to November 2000 in the eastern part of Japan around Tokyo area. A total of 2,895 water samples were examined for the possible occurrence of Legionella, and 904 (31%) were demonstrated to be positive. Among the various water sources, Legionella were frequently detected both in whirlpool bathes and in cooling towers, of which detection rates were 48% and 46%, respectively. More precisely, occurrence of Legionella was higher in private-use whirlpool bathes than those for public-use; namely, the positive rate was 71% in bathes accommodated in private houses, 63% in company's club houses, 62% in company dormitories for employees, and 51% in old-people's homes. Occurrence of Legionella, on the other hand, was less common (< or = 30%) in bathes for public-use such as those installed in hotels and in hot spring facilities. Typing of L. pneumophila serogroups revealed that SG5 (34%) was dominant in whirlpool bath waters followed by SG3 (22%), whereas SG1 (32%) was dominantly found in cooling tower waters.
