| Outline of Final Research Achievements |
In this study we performed amoebic co-culture method to investigate legionella contamination of environmental water samples. Of 120 water samples, 75.1% (91 samples) were positive for Legionella spp. by amoebic co-culture method combined with real-time PCR method. we performed Sequence-Based Typing to analyze relationship between genotypes and inhibit environment of L. pneumophila detected by amoebic co-culture method and mip gene PCR, however we could not obtain positive data. Among the 91 positive samples, 17 samples (14.2%) showed over 10% increase of bacteria numbers. Following sequence analysis found LLAP type such as L. lytica from the positive samples. Our results suggested that Legionella spp. including viable but non-culturable form highly inhabited environmental water.
