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.
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]
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.
Mycobacteria are a family of small, rod-shaped bacilli that can be classified into three main groups for diagnosis and treatment: Mycobacterium tuberculosis complex, which can cause tuberculosis: M. tuberculosis, M. bovis, M. africanum, M. microti and M. canettii; M. leprae and M. lepromatosis, which cause Hansen's disease, also called leprosy
In January 2024, a publication by an Australian research group demonstrated significant genetic similarity between Mycobacterium ulcerans in humans and possums, compared to PCR screening of M. ulcerans from trapped Aedes notoscriptus mosquitoes, and concluded that Mycobacterium ulcerans, the causative pathogen of Buruli ulcer, is transmitted by mosquitos.
Mycobacterium: M. leprae: Prolonged human-human contact, e.g. through exudates from skin lesions to abrasion of other person [33] Leprosy (Hansen's disease): [33] granulomas of the nerves, respiratory tract, skin, and eyes.
