Mycobacterium massiliense

Mycobacterium massiliense is a species of bacteria belonging to the Mycobacterium genus. It is a non-tuberculous mycobacterium (NTM) and is often associated with lung disease and skin infections.

Taxonomy

The species was first described in 2004 by Adékambi et al., who isolated it from the sputum of a patient with pulmonary disease. It is part of the Mycobacterium abscessus complex, a group of closely related species that also includes Mycobacterium bolletii and Mycobacterium abscessus sensu stricto.

Pathogenesis

Mycobacterium massiliense is an opportunistic pathogen, meaning it primarily causes disease in individuals with weakened immune systems. It can cause a variety of infections, including lung infections, skin infections, and soft tissue infections. The bacteria can be resistant to many antibiotics, making infections difficult to treat.

Epidemiology

Mycobacterium massiliense is found worldwide, but is most commonly reported in the United States, South Korea, and Brazil. It is thought to be acquired from the environment, particularly from water and soil.

Treatment

Treatment of Mycobacterium massiliense infections can be challenging due to the bacteria's inherent resistance to many antibiotics. A combination of antibiotics is typically used, and treatment can last for several months. Surgical intervention may also be necessary in some cases.
