What is a nontuberculous mycobacterial infection?

Nontuberculous mycobacterial (NTM) lung disease is a general term for a group of disorders characterized by exposure to specific bacterial germs known as mycobacteria. These germs are found in the water and soil and are common throughout the environment as a whole. They usually do not cause illness.

Is non Tuberculosis mycobacterium fatal?

In addition to scars, cavities or pits also form in your lungs. This could lead to lung failure. But NTM lung disease isn’t usually fatal. It’s less common, but NTM infections can also show up in your skin, bones, lymph nodes, or all over your body.

Can NTM lung disease be cured?

A cure for NTM is possible and long-term success rates of treating this infection can be as high as 86%. If a cure is not possible, treatment may allow for stabilization of lung disease and prevention of continued lung destruction.

How long can you live with MAC disease?

Conclusions. Despite high heterogeneity, most studies in patients with MAC pulmonary disease document a five-year all-cause mortality exceeding 25%, indicating poor prognosis.

Can Mycobacterium go away on its own?

Often, if you clear your mucus regularly and take regular exercise, NTM infections can go away. But if an NTM infection continues, it can be serious, and you may need to take tablets to treat it for a year or two to clear it.

How long can you live with NTM lung disease?

The median survival time was 13.0 years (95 % CI 5.9–20.1) for pulmonary MAC but 4.6 years (95 % CI 3.4–5.9) for pulmonary other NTM.

What disease does Mycobacterium cause?

Mycobacterium abscessus [mī–kō–bak–tair–ee–yum ab–ses–sus] (also called M. abscessus) is a bacterium distantly related to the ones that cause tuberculosis and Hansen’s Disease (Leprosy).

Is there such a thing as a nontuberculous mycobacteria?

Jump to navigation Jump to search. Nontuberculous mycobacteria (NTM), also known as environmental mycobacteria, atypical mycobacteria and mycobacteria other than tuberculosis (MOTT), are mycobacteria which do not cause tuberculosis or leprosy (also known as Hansen’s disease). NTM do cause pulmonary diseases that resemble tuberculosis.

What causes nontuberculous mycobacteria ( NTM ) lung disease?

Nontuberculous mycobacteria (NTM) are organisms commonly found in soil and water in many parts of the world. The great majority of NTM lung disease in the U.S. is caused by Mycobacterium avium complex (MAC).

Why are NTM sequences important for mycobacteria?

Growth rate differences are significant, and because 16S rDNA sequences of rapidly and slowly growing mycobacteria are so distinct; they should be assigned to separate genera ( Stahl and Urbance, 1990 ). A list of NTM species of public health significance is provided in Table 2.

Can a mycobacteria be detected in the environment?

Most environmental mycobacteria can be detected microscopically and cultured on media suitable for M. tuberculosis (see p. 212 ). Great care must be taken to differentiate true disease from transient colonization or superinfection.
