To make out of the situation of the environmental contamination by legionellae at subway stations in Shanghai. During Mar～Nov 2001 at 4 subway stations in Shanghai,the improved technique was used to isolate and identify legionellae from 102 water samples of air condition cooling towers. 46 legionella strains were detected out,the rate of environmental contamination was about 45 10% (46/102). [Conclusion] The status of the contamination by legionella in subway stations is very critical in Shanghai,great efforts should be put for it to prevent legionnaires disease outbreak.
