It was formerly known as Mycobacterium balnei. [2] The strain marinum was first identified by Joseph D. Aronson in 1926 and it is observed as a pathogenic mycobacterium [3] causing tuberculosis-like infections in fish (mycobacteriosis) and skin lesions in humans. [3] [4] The bacteria grows optimal at a temperature around 30 °C. [4]
Model of the Mycobacterium spp. cell envelope with 3-D protein structures. Mycobacteria are aerobic with 0.2-0.6 μm wide and 1.0-10 μm long rod shapes. They are generally non-motile, except for the species Mycobacterium marinum, which has been shown to be motile within macrophages. [8] Mycobacteria possess capsules and most do not form ...
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 tuberculosis, Mycobacterium ulcerans and numerous other organisms. Mycobacterium xenopi is also a nonchromogen.
Mycolactone is a polyketide-derived macrolide produced and secreted by a group of very closely related pathogenic mycobacteria species including M. ulcerans, M. liflandii (an unofficial designation), M. pseudoshottsii, and some strains of M. marinum. These mycobacteria are collectively referred to as mycolactone-producing mycobacteria or MPM ...
Zebrafish larvae are optically transparent and lend themselves to genetic manipulation; by infecting them with their natural pathogen, Mycobacterium marinum, a bacterium that causes tuberculosis in fish and is a close genetic relative of the bacteria that cause tuberculosis in humans, she could carefully track the infection while manipulating ...
Slow growing M. marinum and M. szulgai are positive in the 14-day arylsulfatase test. [2] Catalase, semiquantitative activity. Most mycobacteria produce the enzyme catalase, but they vary in the quantity produced. Also, some forms of catalase are inactivated by heating at 68°C for 20 minutes (others are stable).
Mycolicibacterium is a genus of Gram-positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales. [1]Members of Mycolicibacterium were demarcated from the larger genus Mycobacterium in 2018 by Gupta et al. based on evidence from various phylogenetic trees constructed based on conserved genome sequences, comparative genomic analyses and average amino acid identity ...
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 ...
