Mycobacterium Tuberculosis Mechanism Of Infection
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. ...Read more
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
Yes: Oral candidiasis (thrush), or vaginosis is commonly seen in people treated with antibiotics. Both usually resolve with local treatment. Systemic candidiasis does occur in patients recovering from severe sepsis, but is not "common" outside the ICU except in the immune compromised. ...Read moreSee 1 more doctor answer
Less than: Staph infections are much more common than candida following a viral pneumonia, but certainly they can occur. Generally, overgrowth of candida that is local (thrush or vaginosis) can occur in any patient. Systemic candidiasis or candidal pneumonia is seen, but usually only in the immune compromised or severely ill patient. ...Read moreSee 1 more doctor answer

How to find the Bug (bacteria, virus, fingi, parassite, mycoplasma etc) that caused an orticaria, acute pneumonia, atypical broncospasm, mass ?
TB treatment failure: Treatment fails if the wrong antibiotics are used (i.e. the organism is or becomes resistant), if the patient doesn't take the medicine as directed for long enough, or if the patient has a compromised immune system such as from AIDS or other issues. Some organisms just don't have effective treatments as well. ...Read more
