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 ...
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 .

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.
This instrument is produced by Becton Dickinson (BD). It is specially designed to accommodate Mycobacteria Growth Indicator Tube (MGIT) and incubate them at 37 °C. The instrument scans the MGIT every 60 minutes for increased fluorescence.
The Global Buruli Ulcer Initiative (GBUI) is a World Health Organization (WHO) initiative to coordinate global efforts to control Buruli ulcer, [1] an infectious disease characterized by the development of painless open wounds. [2]
There is now considerable evidence to suggest that this disease is an infection. Mycobacterium ulcerans has recently been isolated from lesions and is unique to tropical ulcers. [5] Early lesions may be colonized or infected by, Bacillus fusiformis (Vincent's organism), anaerobes and spirochaetes.
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 ...
Rapid growing mycobacterium consists of organism of the Mycobacterium fortuitum group and Mycobacterium chelonae/Mycobacterium abscessus group [1] and these usually cause subcutaneous abscesses or cellulitis following trauma in immunocompetent patients.
