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 ...
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 ]
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 .
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 ...
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.
Scabies (also sometimes known as the seven-year itch) is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, variety hominis. The word is from Latin: scabere, lit. 'to scratch'. The most common symptoms are severe itchiness and a pimple -like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually ...
Eosinophilic ulcer of the oral mucosa (eosinophilic ulcer of the tongue, Riga–Fede disease, traumatic eosinophilic granuloma) Eosinophilic ulcer of the oral mucosa; Eosinophilic vasculitis; Erythema toxicum neonatorum (erythema toxicum, toxic erythema of the newborn) Granuloma faciale; Hypereosinophilia; Hypereosinophilic syndrome
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.
