Mycobacterium Avium Intracellulare Contagious
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. ...Read moreSee 1 more doctor answer
What is the most common with aids patients -- mycobacterium avium-complex or mycobacterium tuberculosis?
Mycobacteria: Mycobacterium intracellulare is something of a difficult bacterium to treat. Depending on the site of infection, you either need an Infectious Diseases specialist or a lung specialist. Sometimes you need both! Usually this germ attacks those that are weakened - either by disease (cancer, AIDS) or some structural problem - such as damaged airways from smoking. There is good treatment, though. ...Read more
Many mycobacteria: There are >200 species of mycobacteria. We worry about mycobacterium tuberculosis because it can be transmitted between people. Atypical mycobacterium, like mai, are not contageous. These are in our h2o supply ; we drink/inhale them. Most are problematic in people w/lung diseases (copd/cystic fibrosis) or those who are immunocompromised (hiv/transplant patients). In normal hosts usually no worry. ...Read more
M. abscessus: Mycobacterium abscessus complex is a group of rapidly growing, multidrug-resistant, nontuberculous mycobacteria. They can cause a whole range of skin and soft tissue diseases, central nervous system infections, bacteremia, and ocular and other infections. Some of the drugs used include clarithromycin, amikacin, and cefoxitin. However treatment really is best coordinated by an ID doc who knows. ...Read more
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
