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.

Journal of Clinical TB and other Mycobacterial Diseases
uberculosis (TB) in the gastrointestinal tract or peritoneum is an uncommon condition in clinical practice. Its rarity, combined with its nonspecific presentations, makes this kind of extrapulmonary tuberculosis difficult to diagnose as it can... mimic other inflammatory or malignant conditions. Delays in treatment and frequent misdiagnosis can lead to hazardous complications. In countries like Ecuador where the disease is endemic, TB should always be considered in the differential diagnosis of a patients who present with nonspecific abdominal symptoms. In these scenarios, laparoscopy can be an invaluable tool when used with sufficiently high clinical awareness and adequate training.
Case presentation
We present the case of a 37-year-old female patient from Ecuador with a 1-year history of abdominal pain, nausea, intermittent vomits, night sweats, and weight loss. After clinical evaluation and a laparoscopic intervention, abdominal TB was detected and promptly treated. Antituberculosis chemotherapy was initiated, and the patient successfully reco
High clinical awareness is imperative when approaching abdominal TB due to its wide spectrum of clinical symptoms and its rarity. Early detection and prompt treatment are critical to minimize the possibility of hazardous complications.

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.
National Tuberculosis Control Program; Mycobacterial Disease Control National AIDS/STD Program
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.
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.

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.
The purpose of this document is to contribute to improved recognition of Buruli
ulcer (Mycobacterium ulcerans infection) and encourage greater efforts in detecting
cases at an early stage of infection.Today, patients can be cured with antibiotics if
diagnosed early, thus avoiding unnecessary suff...ering and disability.We hope that
all users of this document will help to achieve these objectives.

Technical Update
Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

Course contents: What is Leprosy? Leprosy is a disease caused by a micro-organism called Mycobacterium leprae
Zoonotic tuberculosis (TB) is a form of TB in people predominantly caused by the bacterial species, Mycobacterium bovis, which belongs to the M. tuberculosis complex. The implications of zoonotic TB go beyond human health. The organism is host-adapted to cattle, where it is refer...red to as bovine TB, and it also causes TB in other animal species including wildlife. Bovine TB has an important economic impact and threatenslivelihoods.

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.
