Principaux faits
L’ulcère de Buruli est une infection chronique débilitante causée par la bactérie Mycobacterium ulcerans.
L’ulcère de Buruli a été signalé dans au moins 33 pays situés dans des régions au climat tropical, subtropical ou tempéré d’Afrique, d’Amérique ...du Sud et du Pacifique occidental.
Cette infection affecte la peau et parfois les os et peut entraîner des déformations et des incapacités permanentes.
Le mode de transmission de cette maladie est inconnu, on ne peut la prévenir.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Buruli ulcer (BU) is a bacterial skin infection that is caused by Mycobacterium ulcerans and mainly affects people who reside in the rural areas of Africa and in suburban and beach resort communities in Australia.
Buruli ulcer is a disease caused by the environmental pathogen Mycobacterium ulcerans that affects skin and soft tissue. It was first described in Australia in 1948 and has been reported in several sub-Saharan African countries since the late 19th century. The disease mainly affects children in rura...l areas and causes lesions and ulcers that can lead to disability if not treated. Recent research has identified a toxin produced by M. ulcerans that may be responsible for the disease's pathogenesis. Efforts are ongoing to understand transmission and develop effective control strategies, including through training of medical professionals and increased detection and treatment of cases.

La tuberculosis o TB es una enfermedad causada por la bacteria Mycobacterium tuberculosis. Esta bacteria por lo general ataca a los pulmones, pero también puede atacar otras partes del cuerpo, como los riñones, la columna vertebral y el cerebro. Si no se trata apropiadamente, la tuberculosis... puede ser mortal.

El agente etiológico de la tuberculosis es el Mycobacterium tuberculosis o bacilo de Koch. Se trata de un bacilo aerobio estricto, ácido-alcohol resistente, sin movilidad, de crecimiento lento y que se inactiva con rayos ultravioleta y temperaturas mayores de 60°C.
L’ulcère de Buruli, une infection causée par Mycobacterium ulcerans, touche plus de 33 pays dans le monde, mais un peu moins de la moitié seulement de ces pays communiquent régulièrement des données sur la maladie à l’OMS.
Buruli ulcer is a chronic, progressive skin disease caused by infection with Mycobacterium ulcerans. It is currently considered to be one of the neglected tropical diseases; less common than tuberculosis but more common than leprosy. The initial lesion is a painless subcutaneous nodule, usually less... than 5 cm diameter and adherent to skin. The nodule typically breaks down centrally after days to weeks forming an ulcer with undermined edges. Thus, the external appearance of the ulcer underestimates the true size of the affected area. The patient remains well and there is no pain unless secondary bacterial infection occurs. Other forms of M. ulcerans disease include a firm plaque lesions that behaves in the same way as the nodule or an oedematous lesion that is more aggressive and extends rapidly resulting in a very large ulcer.
Any age group can be affected by Buruli ulcer diseases, but the incidence peaks at 5 to 15 years. Ulcers are most frequently on the limbs but can be on the trunk or head, sometimes with catastrophic consequences such as loss of sight or loss of breast or genital tissue. Healing close to a joint can result in contracture, and sometimes there is so much tissue destruction on a limb that amputation is unavoidable. Occasionally osteomyelitis occurs in bone adjacent to a skin lesion but involvement of other organs is rare. Disseminated disease with HIV has been reported.
