Some types of mycobacteria, usually Mycobacterium marinum, grow in swimming pools and even in home aquariums. The Mycobacterium tuberculosis forms a complex with other higher related bacteria called the M. tuberculosis complex that consists of 6 members: Mycobacterium tuberculosis and Mycobacterium africanmum, which infect humans; Mycobacterium microti, which infects vole; Mycobacterium bovis, which infects other mammalian species as well as humans; M. bovis BCG, a variant of Mycobacterium bovis and Mycobacterium canettii, a pathogen that infects humans. HIV weakens a person's immune system so it can't fight the TB germs. There are a variety of ways in which NTM are different than TB.

There are two versions of TB, pulmonary TB (PTB) and extrapulmonary TB (EPTB). Acetic acid might be used as an inexpensive and non-toxic disinfectant against drug-resistant tuberculosis (TB) bacteria as well as other stubborn, disinfectant-resistant mycobacteria. They can both be transmitted by respiratory droplets and cause symptoms like fever, fatigue and cough.

The BCG vaccine, which contains bacteria similar to the bacteria that cause TB. TB that affects the lungs (pulmonary TB) is the most contagious type, but it usually only spreads after prolonged exposure to someone with the illness. Whilst these pathogenic species exhibit some phenotypic differences, they are genetically very similar and are therefore often classed as the ‘ Mycobacterium tuberculosis complex’. The TB pathogen is wrapped in a thick envelope that is difficult to penetrate, especially compared to other bacteria. EPTB occurs outside of the lungs – areas afflicted include the stomach, lymph nodes, or various bones or joints. The bacteria that cause tuberculosis (TB) are classified as mycobacteria.
