Outline of Final Research Achievements |
The genetic analysis of 14 collected strains of Mycobacterium kyorinense clarified that they harbored polymorphism in 16S rRNA, suggesting the genetic diversity among the strains of this organism. In addition, analysis of Mycobacterium celatum, a species closely related to M. kyorinense, revealed that the sequences of several housekeeping genes of M. celatum type 2 are identical to those of M. kyorinense; therefore, we propose reclassification of M. celatum type 2 as M. kyorinense. Furthermore, the whole genome analysis of the type strain of M. kyorinense suggested that the mechanism underlying the resistance to antibiotics of this organism is significantly different from those of M. tuberculosis.
