Mycobacteria are a bacterial genus. Mycobacteria are acid-alcohol fast bacteria (AAFB), because they can only be visualised by special acid-alcohol Ziehl-Neelsen staining.
Not all of them are pathogenic; some are pathogenic in the immune compromised. They include the causes of:
Other mycobacteria that can occasionally infect humans include:
- Mycobacterium microti
- Mycobacterium avium
- Mycobacterium malmoense
- Mycobacterium ulcerans - produces Buruli ulcer
- Mycobacterium marinum - produces fishtank granuloma
