Consequences and treatment for mycobacterium avium intracellulare?

Complex: M. Avium- intracellulare (mac) infections can result in lung and other organ damage, depending on the severity of immunodeficiency. In people with an intact immune system, mac infection is a slow process and can take years before therapy is initiated (2 or 3 antibiotics- e.g. Ethambutol, cipro, (ciprofloxacin) and rifabutin). Therapy can last a minimum of 12 months if a lung infection is involved.

Atypical mycobacterium, like mai, are not contageous. These are in our h2o supply ; we drink/inhale them.

What is the pathophysiology of mycobacterium tuberculosis?

What is the pathophysiology of mycobacterium tuberculosis?

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.
