Aquarium granuloma (also known as fish tank granuloma and swimming pool granuloma) is a rare skin condition caused by a non-tubercular mycobacterium known as Mycobacterium marinum. [2] Skin infections with M. marinum in humans are relatively uncommon, and are usually acquired from contact with contaminated swimming pools, aquariums or infected ...
Mycobacterium marinum is an acid-fast, aerobic bacterium which can infect humans. [4] Infection is usually associated either with swimming, preparing sea food, or with keeping or working with aquarium fish. [2] Infections of humans are rare due to the chlorination of water. [4]
Runyon III organisms (nonchromogens) are slow-growing and never produce pigment, regardless of culture conditions. The group includes Mycobacterium avium and Mycobacterium intracellulare (together known as the MAC complex), Mycobacterium ulcerans and numerous other organisms. Mycobacterium xenopi is also a nonchromogen.
Mycobacterium is a genus of over 190 species in the phylum Actinomycetota, assigned its own family, Mycobacteriaceae. This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis ( M. tuberculosis ) and leprosy ( M. leprae ) in humans.
In 1959, botanist Ernest Runyon put these human disease-associated bacteria into four groups (Runyon classification): [4] Photochromogens develop pigments in or after being exposed to light. Examples include M. kansasii, M. simiae, and M. marinum. [4] Scotochromogens become pigmented in darkness. Examples include M. scrofulaceum and M. szulgai. [4]
M. ulcerans is a mycobacterium, closely related to Mycobacterium marinum which infects aquatic animals and, rarely, humans. [9] It is more distantly related to other slow-growing mycobacteria that infect humans, such as Mycobacterium tuberculosis, which causes tuberculosis, and Mycobacterium leprae, which causes leprosy. [10]

Mycobacterium ulcerans is a species of bacteria found in various aquatic environments. The bacteria can infect humans and some other animals, causing persistent open wounds called Buruli ulcer . M. ulcerans is closely related to Mycobacterium marinum , from which it evolved around one million years ago, and more distantly to the mycobacteria ...
