| Outline of Final Research Achievements |
In order to prevent the nontuberculous mycobacterial diseases originated from environments, clarification of the dynamics of nontuberculous mycobacteria in the environment is indispensable. In this study, we focused on the soil considered as one of infectious sources, and clarified the mycobacterial abundance and community structure using gene-targeting methods.
We found that there were various species of nontuberculous mycobacteria in the environment. Among these, focusing on Mycobacterium avium, it was found that it existed widely in the soil analyzed in this study, and it might dominate in the environment that repeats drying and wetting like flower pots.
These results became the fundamental knowledge for understanding the dynamics of nontuberculous mycobacteria in the environment, and we can contribute to prevent the nontuberculous mycobacterial diseases from the viewpoint of environmental microbiology.
