It is not fully understood how the genetic differences between<unk>  and M. tuberculosis give rise to the lower pathogenicity of the former. However, it is known that the Region of Difference 9 (RD9) is lacking in<unk>  but present in M. tuberculosis.<unk>  also has notable differences in lipid catabolism and metabolism. Additionally, virulence pathways such as the dosR/Rv0081 regulon or ESAT-6 regulation are disrupted in<unk> .
