| Research Abstract |
A survey of water samples in Yamanashi Prefecture, Japan, was conducted in order to determine the relationship between the growth of colony-forming Legionella and water quality parameters. Legionella was also analyzed by real time PCR (RT-PCR). Colony-forming Legionella was not detected in water samples in which phosphate ions were not measured. To control phosphate ion may be effective to protect from Legionella growth. RT-PCR Legionella was measured in all of the samples that were negative for colony-forming Legionella. The survival rates (colony-forming Legionella/RT-PCR Legionella × 100) were 0.1% to 0.5%. DNA pattern analysis of 15 species in the genus Legionella pneumophila was carried out by a novel DNA pattern analysis method (Genopattern method). DNA pattern of 15 species exhibits a specific pattern, which is different from other's. The result suggests determination by Genopattern method may be applicable to distinguish species of Legionella.
