Mycobacterium Tuberculosis Mechanism Of Infection
Usually not: Mycobacterial tuberculosis infection can affect any part of the body and depending on the organ affected may have dull pain especially if skin and/or bone are involved. In vast majority of patients with TB pain is not a dominant symptom.
Mycobacterium tuberculosis is an infectious organism that spreads by droplets coughed out by an infected person. Infection is established initially in lungs, but can spread within lungs & to other body parts, or can become latent, with reactivation occurring years to decades later. With effective treatment, it can be completely eliminated although drug resistant ...Read more
Chronic infection: Mycobacterium tuberculosis is an infectious organism that spreads by droplets coughed out by an infected person. Infection is established initially in lungs, but can spread within lungs & to other body parts, or can become latent, with reactivation occurring years to decades later. With effective treatment, it can be completely eliminated although drug resistant strains are becoming common.
For TB: Treatment is empiric at first, most commonly using four drugs to avoid the development of resistant organisms. After testing of the bug (which can take 8 weeks), treatment can be narrowed to two drugs to which it is susceptible, but continued for a total of 6 months (at least). Treatment of TB works best when it is administered under direct supervision of a qualified public health official.See 1 more doctor answer
Yes: And you will hurt everyone you love and live with by infecting them as well. In many countries you don't get to decide. You either take the treatment voluntarily or you get detained and kept in isolation. This applies to open tuberculosis. If you have latent tuberculosis, it's a different story. Chances of death from latent TB are almost zero, unless it turns into the open form.See 1 more doctor answer
Multi-drug therapy: Mycobacterium tuberculosis is the bacterium that causes tuberculosis. This was the among the most common causes of lung disease in the early 20th century when it was called "consumption." Nowadays it is unusual in the US but still common in the 3rd world and very serious. Treatment is a regimen of 2 to 4 drugs for many months. Resistant strains are cropping up, which complicates matters greatly.See 1 more doctor answer
You don't: The lab does, on special media. If you try it yourself, and you actually have somebody with active TB to grow it from, you'll generate a mass of nasty bacteria and if you don't know exactly what you are doing, you can make everybody around you very sick.
Complex: Mtb is acquired thru respiratory route and replicates in the lung before asymptomatically disseminates to other organs. After about 6-8 weeks, the immune system starts to respond to the bug, walling the bacilli off in granulomas. Other than a positive skin test, 90% of people stay well. Of the rest, half will "reactivate" within 2 yrs and the others later sometimes due to immune suppression.
It's complicated: Tb needs to be treated with several drugs to which it is susceptable at the same time to prevent the emergence of mutational resistance. It also needs to be treated for at least 6 months. In many 3rd world countries TB meds can be purchased over the counter and people take them incorrectly and not long enough. In usa some pts are non compliant with treatment. Both these cause resistance.
Not for prime time: Cord factor is a molecule that enhances virulence of mtb. Usually the non-tuberculous mycobacterium don't have it so it can be used to differentiate between the infections. Why? Mtb is considered contagious & non-tb mycobacterium are not frequently so. Experimentally this factor has been looked at as a quick test to differentiate between the 2 types of infection. Not yet commercially available.
Clarify with doc: It is either mycobacterium tuberculosis or mycobacterium avium or something else. Probably the lab is working on it. Clarify with your doc although the final result may take a few more days.

Is "mycobacterium tuberculosis " can cause kyphosis or scoliosis directly (without affecting the lungs)?!
Yes: It is possible to get tuberculosis of the spine which can cause significant damage and deformity. However, it usually has pain along with the infection. The TB germs may enter the body through the lungs but then be controlled there but circulate and cause their major damage outside the lungs sometime later.See 1 more doctor answer

Inflammation: Tb is an infection which can cause an inflammatory reaction and scar tissue can be the result of that process.
Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more
