True about mycobacterium other than tuberculosis-
**Core Concept**
Mycobacteria are a genus of Actinobacteria, with many species causing diseases in humans. The most well-known species is Mycobacterium tuberculosis, which causes tuberculosis (TB). However, there are other species of mycobacteria that can cause various diseases, including infections of the skin, lungs, and other organs.
**Why the Correct Answer is Right**
Mycobacteria other than M. tuberculosis can cause a range of diseases, including:
- Mycobacterium leprae, which causes leprosy, a chronic bacterial infection that affects the nerves, skin, and mucous membranes.
- Mycobacterium avium complex (MAC), which can cause pulmonary disease and disseminated infection in immunocompromised individuals.
- Mycobacterium kansasii, which can cause pulmonary disease similar to TB.
- Mycobacterium abscessus, which can cause skin and soft tissue infections.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided.
**Option B:** This option is not provided.
**Option C:** This option is not provided.
**Option D:** This option is not provided. (However, if this option were to be provided, it would likely be incorrect as well, since M. tuberculosis is the only mycobacterium commonly referred to by a single name, and other species have more descriptive names.)
**Clinical Pearl / High-Yield Fact**
Mycobacteria other than M. tuberculosis can be difficult to diagnose and treat due to their complex cell walls and resistance to many antibiotics. It's essential to consider these organisms in the differential diagnosis of chronic infections, particularly in immunocompromised patients.
