Answers:
Any infection of the bone will cause visible deformity -- if left untreated long enough!. It is not a unique property of mycobacteria, just a testament to the chronicity of the infection!. Remember that for someone to have any clinical symptoms of TB osteomyelitis their infection MUST have been present for 6 months or longer - probably years in most cases!.
If you have a strep or staph infection on a bone for 6 months - the bones are incredibly hypertrophied and moth-eaten !. A typical diabetic foot infection left untreated for that long will present with a toe that looks like a huge sausage!.
So it's not anything special about the mycobacterium, just the fact that the infection has been present for so long prior to diagnosis!. Any source of chronic inflammation in the bone is going to cause increased osteoblastic and osteoclastic activity that results in increased bony remodeling!.Www@Answer-Health@Com

Yes because bacillus Mycobacterium tuberculosis is a very gooey bacteria that grows very slowly!. Sometime its introduces into your body via eyes or sinuses as well as lungs!. almost anything considered mucosa membrane!. Its a very hard bug to fight because it grows very slowly and is very gooey !.They will try to work there way to the bones and joints throw the lymphatic system!. When the white cells macrophage the bacillus it doesn't kill it What it does it just contains the bacillus!. If the immune system is compromised the bacillus gets lose in those areas!. The deformity of the bones is then caused by the calcification of the bug I think!. Not sure of the pathological process!. to much research right now!. Remember hunch back of notre dame!. Allmost the same bug Mycobacterium leprea(lepracy) Red light thearpy work very wellWww@Answer-Health@Com
TB can cause a septic arthritis, I've seen a couple cases in the hip, and joint deformities secondary to that process!. It can also cause a wicked osteomyelitis/septic arthritis in the spine - pott's disease!.Www@Answer-Health@Com
