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 more
What is the most common with aids patients -- mycobacterium avium-complex or mycobacterium tuberculosis?
Both are common: Most of the mai cases occur with low CD4 counts. Tb not necessarily. ...Read more
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
Not really: This bug is everywhere in our environment and only people with immune problems typically are affected/ ...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
ThroughTheLab: You can not culture Mycobacterium Tuberculosis by your self. The specimen has to be collected by your doctor or healthcare provider properly and sent to be Bacteriological Laboratory to be cultured where it is incubated for several days to grow the mycobacterium as it is slow growing bacteria ...Read more
Infects and prevails: Mycobacterium Tuberculosis is a bacteria that causes Disease Tuberculosis in humans. The most common infection is in the lungs but it can infect other organs in the body as well. How it calls infection is the same way any other infectioius agent enters our body. Our body tries to fight the infection on it's own and many are able to survive that. While others succumb to it and end up with disease ...Read more
Cell wall: The complex lipids in the cell wall produce the staining. ...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
It depends: On whether the individual has underlying diseases that might make the infection worse or affect mortality as well. ...Read more
InfectionAndSpread: Mycobacterium Tuberculosis Bacteria attacks healthy&some not so healthy people when they are exposed to some one who is already infected&has active infection with positive bacteria in their lungs. And by close contact one can acquire that bacteria. Not every one who gets infected comes up with the active disease but some do and others overcome with body's resistannce. Those infected are contagious ...Read more
Unknown: Mycobacteria including mycobacterium tuberculosis can remain active on dry surfaces for months. However, it is unknown how long mycobacteria laprae would remain active. ...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. ...Read more
AntibioticResistance: Resistance is caused by non compliance as people do not take two or three drugs for six months or more. It in the long term make some antibiotics ineffective due to bacterial resistance. But another factor is the Bacteria become smart and as the Antibiotics are used over the years find a different mode to survive like all other Antibiotcs we have used over the years. It is a big problem ...Read more
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. ...Read more
I have been in contact with laboratory-grown specimens of Mycobacterium phlei. I would like to know the symptoms just in case of. Thank you.
Mycobacteria are unlikely to infect you thus symptoms "just in case" are impossible to predict!
Hope this is helpful
