Buruli ulcer has been the subject of scientific research since the description of M. ulcerans in 1948, and the demonstration that the bacteria could cause ulcers in laboratory animals. [ 11 ] [ 54 ] While several animals are susceptible to M. ulcerans ulcers, mice (particularly BALB/c and C57BL/6 mice) are most commonly used to model Buruli ...
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 which cause tuberculosis and leprosy .
Deep ulcers can cause scarring of muscles and tendons, resulting in permanent disability. Buruli ulcer is caused by skin infection with bacteria called Mycobacterium ulcerans . The mechanism by which M. ulcerans is transmitted from the environment to humans is not known, but may involve the bite of an aquatic insect or the infection of open wounds.
A 2004 WHO resolution "called for increasing surveillance and control, and for intensified research to develop tools to diagnose, treat and prevent" Buruli ulcer. [4] In 2009, a strategy to promote early detection and provide wider access to antibiotics was adopted. [6]
This grows larger over days to weeks, forming an open ulcer (biopsy images pictured). Deep ulcers can cause scarring of muscles and tendons, resulting in permanent disability. The World Health Organization (WHO) recommends treating Buruli ulcer with a combination of the antibiotics rifampicin and clarithromycin. Regular cleaning and dressing of ...

Apparently having this giant open wound typically doesn't lead to systemic disease and death: a 2019 review says Buruli ulcer does not kill, but it is an important cause of morbidity because of scarring and fibrosis, my now-declared favorite review (2018) says only [Ulcers could remain small, or grow enormous and cause major disability]. With ...
English: A map of Africa with shading representing the number of cases of Buruli ulcer in 2018, according to the World Health Organization's Global Health Observatory data repository. Shading is in four levels: 1-150 cases - Yellow 151-300 cases - Orange 301-450 cases - Light red 451+ - Dark red (applies only to Ghana's 630 cases).
