| Outline of Final Research Achievements |
The modern subfamily of Beijing lineage, one of the genetic groups of Mycobacterium tuberculosis, is considered more virulent than other genetic groups. In this study, I investigated genetic situation to elucidate situation of spread of the tubercle bacilli isolated from two patients groups: younger than 40 years and resident in the Airin area. As a result, it was revealed that the proportion of strains belonging to the modern Beijing subfamilies has increased from both patients populations.In Airin area, TB patients aged 50 to 80 accounted for more than 80% of the total population. The situation suggests that the modern Beijing subfamily strains has increased in not only young fellows but also old and middle aged people.
