A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p1160)
The constant presence of diseases or infectious agents within a given geographic area or population group. It may also refer to the usual prevalence of a given disease with such area or group. It includes holoendemic and hyperendemic diseases. A holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). A hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. (Last, A Dictionary of Epidemiology, 3d ed, p53, 78, 80)

Promising clinical efficacy of streptomycin-rifampin combination for treatment of buruli ulcer (Mycobacterium ulcerans disease). (1/134)

According to recommendations of the 6th WHO Advisory Committee on Buruli ulcer, directly observed treatment with the combination of rifampin and streptomycin, administered daily for 8 weeks, was recommended to 310 patients diagnosed with Buruli ulcer in Pobe, Benin. Among the 224 (72%) eligible patients for whom treatment was initiated, 215 (96%) were categorized as treatment successes, and 9, including 1 death and 8 losses to follow-up, were treatment failures. Of the 215 successfully treated patients, 102 (47%) were treated exclusively with antibiotics and 113 (53%) were treated with antibiotics plus surgical excision and skin grafting. The size of lesions at treatment initiation was the major factor associated with surgical intervention: 73% of patients with lesions of >15 cm in diameter underwent surgery, whereas only 17% of patients with lesions of <5 cm had surgery. No patient discontinued therapy for side effects from the antibiotic treatment. One year after stopping treatment, 208 of the 215 patients were actively retrieved to assess the long-term therapeutic results: 3 (1.44%) of the 208 retrieved patients had recurrence of Mycobacterium ulcerans disease, 2 among the 107 patients treated only with antibiotics and 1 among the 108 patients treated with antibiotics plus surgery. We conclude that the WHO-recommended streptomycin-rifampin combination is highly efficacious for treating M. ulcerans disease. Chemotherapy alone was successful in achieving cure in 47% of cases and was particularly effective against ulcers of less than 5 cm in diameter.  (+info)

Systemic and local interferon-gamma production following Mycobacterium ulcerans infection. (2/134)

Buruli ulcer disease (BUD) is an emerging predominantly tropical disease caused by Mycobacterium ulcerans. The initial pre-ulcerative skin lesion often breaks down into an ulcer with undermined edges. Healing is common but may require considerable time, and scarring often results in functional limitations. Considerable evidence has now emerged that patients with early BUD cannot mount a sufficient protective T helper 1 (Th1) cell response to M. ulcerans, but uncertainty remains as to whether immune protection is restored over time. This study investigates the Th1 cell response of patients with various stages of BUD on mycobacterial antigens. We measured interferon (IFN)-gamma levels after ex vivo whole blood stimulation with tuberculin purified protein derivative (PPD), and compared the Th1 cell response of individuals with pre-ulcerative, ulcerative and healed BUD as well as healthy controls. Moreover, the systemic Th1 cell response was related to histopathological features in the various stages of surgically resected BUD lesions. We show that patients with ulcerative and healed BUD produce significantly higher IFN-gamma levels after mycobacterial ex vivo whole blood stimulation than healthy controls, and that patients with a granulomatous tissue response produce higher IFN-gamma levels than individuals without. We therefore suggest that the mounted Th1 cell response in ulcerative BUD patients might be related to their histopathological tissue response.  (+info)

Evolution of two distinct phylogenetic lineages of the emerging human pathogen Mycobacterium ulcerans. (3/134)

BACKGROUND: Comparative genomics has greatly improved our understanding of the evolution of pathogenic mycobacteria such as Mycobacterium tuberculosis. Here we have used data from a genome microarray analysis to explore insertion-deletion (InDel) polymorphism among a diverse strain collection of Mycobacterium ulcerans, the causative agent of the devastating skin disease, Buruli ulcer. Detailed analysis of large sequence polymorphisms in twelve regions of difference (RDs), comprising irreversible genetic markers, enabled us to refine the phylogenetic succession within M. ulcerans, to define features of a hypothetical M. ulcerans most recent common ancestor and to confirm its origin from Mycobacterium marinum. RESULTS: M. ulcerans has evolved into five InDel haplotypes that separate into two distinct lineages: (i) the "classical" lineage including the most pathogenic genotypes - those that come from Africa, Australia and South East Asia; and (ii) an "ancestral" M. ulcerans lineage comprising strains from Asia (China/Japan), South America and Mexico. The ancestral lineage is genetically closer to the progenitor M. marinum in both RD composition and DNA sequence identity, whereas the classical lineage has undergone major genomic rearrangements. CONCLUSION: Results of the InDel analysis are in complete accord with recent multi-locus sequence analysis and indicate that M. ulcerans has passed through at least two major evolutionary bottlenecks since divergence from M. marinum. The classical lineage shows more pronounced reductive evolution than the ancestral lineage, suggesting that there may be differences in the ecology between the two lineages. These findings improve the understanding of the adaptive evolution and virulence of M. ulcerans and pathogenic mycobacteria in general and will facilitate the development of new tools for improved diagnostics and molecular epidemiology.  (+info)

Environmental and health-related risk factors for Mycobacterium ulcerans disease (Buruli ulcer) in Benin. (4/134)

We conducted a case-control study to investigate the association between Buruli ulcer (BU) and environmental- and health-related behaviors in southern Benin. Hospital BU cases (N = 324) and sex- and age-matched neighborhood controls (N = 1,173) answered a questionnaire. Regular use of soap for washing, treating injuries with soap or antibiotic powder, and frequent contact with flowing water appeared protective against BU.  (+info)

Primary culture of Mycobacterium ulcerans from human tissue specimens after storage in semisolid transport medium. (5/134)

Tissue specimens collected from patients with clinically suspected Buruli ulcer treated in two Buruli ulcer treatment centers in Benin between 1998 and 2004 were placed in semisolid transport medium and transported at ambient temperature for microbiological analysis at the Institute of Tropical Medicine in Antwerp, Belgium. The impact of the delay before microbiological analysis on primary culture of Mycobacterium ulcerans was investigated. The length of storage in semisolid transport medium varied from 6 days to 26 weeks. Of the 1,273 tissue fragments positive for M. ulcerans DNA by an IS2404-specific PCR, 576 (45.2%) yielded positive culture results. The sensitivity of direct smear examination was 64.6% (822/1,273 tissue fragments). The median time required to obtain a positive culture result was 11 weeks. Positive cultures were obtained even from samples kept for more than 2 months at ambient temperatures. Moreover, there was no reduction in the viability of M. ulcerans, as detected by culture, when specimens remained in semisolid transport medium for long periods of time (up to 26 weeks). We can conclude that the method with semisolid transport medium is very robust for clinical specimens from patients with Buruli ulcer that, due to circumstances, cannot be analyzed in a timely manner. This transport medium is thus very useful for the confirmation of a diagnosis of Buruli ulcer with specimens collected in the field.  (+info)

Development of highly organized lymphoid structures in Buruli ulcer lesions after treatment with rifampicin and streptomycin. (6/134)

BACKGROUND: Buruli ulcer caused by Mycobacterium ulcerans is an infection of the subcutaneous tissue leading to chronic necrotising skin ulcers. The pathogenesis is associated with the cytocidal and immunosuppressive activities of a macrolide toxin. Histopathological hallmark of progressing disease is a poor inflammatory response despite of clusters of extracellular bacilli. While traditionally wide excision of the infected tissue was the standard treatment, provisional WHO guidelines now recommend an eight week pre-treatment with streptomycin and rifampicin. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a detailed immunohistochemical analysis of tissue samples from Buruli patients who received antibiotic treatment. Cellular immune response along with bacterial load and distribution were monitored. We demonstrate that this treatment leads to the development of highly organized cellular infiltration surrounding areas of coagulative necrosis. Diffuse infiltrates, granulomas and dense lymphocyte aggregation close to vessels were observed. Mycobacterial material was primarily located inside mononuclear phagocytes and microcolonies consisting of extracellular rod-shaped mycobacteria were no longer found. In observational studies some patients showed no clinical response to antibiotic treatment. Corresponding to that, one of five lesions analysed presented with huge clusters of rod-shaped bacilli but no signs of infiltration. CONCLUSIONS/SIGNIFICANCE: Results signify that eight weeks of antibiotic treatment reverses local immunosuppression and leads to an active inflammatory process in different compartments of the skin. Structured leukocyte infiltrates with unique signatures indicative for healing processes developed at the margins of the lesions. It remains to be analysed whether antibiotic resistance of certain strains of M. ulcerans, lacking patient compliance or poor drug quality are responsible for the absent clinical responses in some patients. In future, analysis of local immune responses could serve as a suitable surrogate marker for the efficacy of alternative treatment strategies.  (+info)

Risk factors for buruli ulcer: a case control study in Cameroon. (7/134)

BACKGROUND: Buruli ulcer is an infectious disease involving the skin, caused by Mycobacterium ulcerans. This disease is associated with areas where the water is slow-flowing or stagnant. However, the exact mechanism of transmission of the bacillus and the development of the disease through human activities is unknown. METHODOLOGY/PRINCIPAL FINDINGS: A case-control study to identify Buruli ulcer risk factors in Cameroon compared case-patients with community-matched controls on one hand and family-matched controls on the other hand. Risk factors identified by the community-matched study (including 163 pairs) were: having a low level of education, swamp wading, wearing short, lower-body clothing while farming, living near a cocoa plantation or woods, using adhesive bandages when hurt, and using mosquito coils. Protective factors were: using bed nets, washing clothes, and using leaves as traditional treatment or rubbing alcohol when hurt. The family-matched study (including 118 pairs) corroborated the significance of education level, use of bed nets, and treatment with leaves. CONCLUSIONS/SIGNIFICANCE: Covering limbs during farming activities is confirmed as a protective factor guarding against Buruli ulcer disease, but newly identified factors including wound treatment and use of bed nets may provide new insight into the unknown mode of transmission of M. ulcerans or the development of the disease.  (+info)

Short report: edematous Mycobacterium ulcerans infection (Buruli ulcer) on the face: a case report. (8/134)

We report a case of a four-year-old Angolan boy with the edematous form of Buruli ulcer on the face and scalp, who was treated at a rural hospital in the Bas-Congo Province, Democratic Republic of Congo. Treatment consisted of a series of surgical interventions and antimycobacterial chemotherapy (rifampin and ciprofloxacin) for two months. This case demonstrates the diagnostic and management difficulties of an edematous lesion of BU on the face and suggests an enhancement of healing and limitation of extent of excision by specific antibiotherapy. The outcome in this patient also underscores the importance of prompt referral of suspected cases and training of health professionals in the early diagnosis of BU.  (+info)

Background: Buruli ulcer may induce severe disabilities impacting on a persons well-being and quality of life. Information about long-term disabilities and participation restrictions is scanty. The objective of this study was to gain insight into participation restrictions among former Buruli ulcer patients in Ghana and Benin. Methods: In this cross-sectional study, former Buruli ulcer patients were interviewed using the Participation Scale, the Buruli Ulcer Functional Limitation Score to measure functional limitations, and the Explanatory Model Interview Catalogue to measure perceived stigma. Healthy community controls were also interviewed using the Participation Scale. Trained native interviewers conducted the interviews. Former Buruli ulcer patients were eligible for inclusion if they had been treated between 2005 and 2011, had ended treatment at least 3 months before the interview, and were at least 15 years of age. Results: In total, 143 former Buruli ulcer patients and 106 community ...
|p|Author Summary Buruli ulcer is known to be endemic to Nigeria since at least 1967, however epidemiological data are rare and incomplete. In total, only 51 Buruli ulcer patients were described in 45 years, all found in Southern Nigeria. This is likely a result of the lack of adequate public health structures dedicated to the diagnosis and treatment of Buruli ulcer in the region. Here, we report a large cohort of 127 PCR-confirmed Nigerian patients treated in neighbouring Benin. Nigerian patients presented mainly severe lesions of Buruli ulcer, and this is linked by the fact that period prior consultation is delayed (24% of the patients waited more than one year between the beginning of the lesion and the consultation in the Buruli ulcer treatment centre in Pobè). We identify South Western Nigeria as an important endemic area for Buruli ulcer, and believe our results will be of importance to Nigerian health authorities, the World Health Organisation and NGOs involved in management of Buruli ulcer.|/p

Buruli ulcer - one of the most neglected among the NTDs - is a debilitating and stigmatising disease. Affecting mainly children in West and Central Africa, the chronic disease results in devastating skin lesions and can lead to permanent disfigurement and long-term disabilities. Buruli ulcer is caused by Mycobacterium ulcerans which belongs to the same family of bacteria that cause tuberculosis (TB) and leprosy. M. ulcerans is found in the environment and, despite considerable research efforts, the mode of transmission of the bacteria to humans remains unclear.. Difficult treatment with adverse side effects. Traditionally, the skin lesions caused by Buruli ulcer have been removed by wide surgical excision. Since 2004, the World Health Organization (WHO) also recommends treatment with a combination of antibiotics: oral rifampicin and injected streptomycin. Surgery is often not an accessible option in low-income settings and the combination therapy requires daily visits in health centres over an ...
Buruli ulcer is a skin disease caused by Mycobacterium ulcerans that is spreading in tropical countries, with major public health and economic implications in West Africa. Multi-analyte profiling of serum proteins in patients and endemic controls revealed that Buruli ulcer disease down-regulates the circulating levels of a large array of inflammatory mediators, without impacting on the leukocyte composition of peripheral blood. Notably, several proteins contributing to acute phase reaction, lipid metabolism, coagulation and tissue remodelling were also impacted. Their down-regulation was selective and persisted after the elimination of bacteria with antibiotic therapy. It involved proteins with various functions and origins, suggesting that M. ulcerans infection causes global and chronic defects in the hosts protein metabolism. Accordingly, patients had reduced levels of total serum proteins and blood urea, in the absence of signs of malnutrition, or functional failure of liver or kidney. Interestingly
Buruli ulcer is a neglected emerging disease that has recently been reported in some countries as the second most frequent mycobacterial disease in humans after tuberculosis. Cases have been reported from at least 32 countries in Africa (mainly west), Australia, Southeast Asia, China, Central and South America, and the Western Pacific. Large lesions often result in scarring, contractual deformities, amputations, and disabilities, and in Africa, most cases of the disease occur in children between the ages of 4-15 years. This environmental mycobacterium, Mycobacterium ulcerans, is found in communities associated with rivers, swamps, wetlands, and human-linked changes in the aquatic environment, particularly those created as a result of environmental disturbance such as deforestation, dam construction, and agriculture. Buruli ulcer disease is often referred to as the mysterious disease because the mode of transmission remains unclear, although several hypotheses have been proposed. The above review

Background: Mycobacterium ulcerans is know to cause the Buruli ulcer. The association between the ulcer and environmental exposure has been documented. However, the epidemiology of the ulcer is not well understood. A hypothesised transmission involves humans being bitten by the water bugs that prey on mollusks, snails and young fishes. Methods: In this paper, a model for the transmission of Mycobacterium ulcerans to humans in the presence of a preventive strategy is proposed and analysed. The model equilibria are determined and conditions for the existence of the equilibria established. The model analysis is carried out in terms of the reproduction number R0. The disease free equilibrium is found to be locally asymptotically stable for R0 , 1. The model is fitted to data from Ghana. Results: The model is found to exhibit a backward bifurcation and the endemic equilibrium point is globally stable when R0 , 1. Sensitivity analysis showed that the Buruli ulcer epidemic is highly influenced by the ...

Background: Mycobacterium ulcerans, the causative agent of Buruli ulcer (BU), is unique among human pathogens in its capacity to produce a polyketide-derived macrolide called mycolactone, making this molecule an attractive candidate target for diagnosis and disease monitoring. Whether mycolactone diffuses from ulcerated lesions in clinically accessible samples and is modulated by antibiotic therapy remained to be established. Methodology/Principal Finding: Peripheral blood and ulcer exudates were sampled from patients at various stages of antibiotic therapy in Ghana and Ivory Coast. Total lipids were extracted from serum, white cell pellets and ulcer exudates with organic solvents. The presence of mycolactone in these extracts was then analyzed by a recently published, fieldfriendly method using thin layer chromatography and fluorescence detection. This approach did not allow us to detect mycolactone accurately, because of a high background due to co-extracted human lipids. We thus used a ...
The World Health Organization (WHO) in collaboration with the Ministry of Health of Ghana organized a four-week training course on the management of Buruli ulcer for 21 doctors from 11 countries at the Agogo Presbyterian Hospital, Agogo in the Ashanti Akim North district.

Those trained will support their national programmes to train health workers in their respective countries in a standardized manner. It ...
Buruli ulcer disease (BUD), caused by Mycobacterium ulcerans, is a neglected bacterial infection of the poor in remote rural areas, mostly affecting children. BUD is a mutilating disease leading to severe disability; it is the third most common mycobacterial infection in immunocompetent people after tuberculosis and leprosy. It is most endemic in West Africa, but cases have been reported from more than 30 countries. Treatment with antibiotics is possible, long-lasting and requires injections; there are cases of treatment failures, and the disease is prone to resistance. A vaccine against M. ulcerans would protect persons at risk in highly endemic areas, and could be used as a therapeutic vaccine to shorten the duration of treatment and prevent relapses. There is considerable evidence supporting the notion that generation of a vaccine is feasible. This article reviews the present state of the art with special emphasis on the immunology of the infection and the prospects for development of a ...
Abstract Recent reports have suggested increases in Buruli ulcer (BU), an infection caused by Mycobacterium ulcerans in west Africa. In 1991, we conducted surveillance for BU in a rural area of Cote d'Ivoire and identified 312 cases of active or healed ulceration. A case-control study was then performed to investigate risk factors for this infection. The rate of illness did not appear to differ between males and females (5.2% versus 7.5%; P = 0.11). The highest rate of illness was seen in the 10-14-year-old age group (143 cases per 1,000 population). New cases increased more than three-fold between 1987 and 1991, and local prevalence of BU was as high as 16.3%. Twenty-six percent of persons with healed ulcers had chronic functional disability. Participation in farming activities near the main river in the region was identified in the case-control study as a risk factor for infection (odds ratio [OR] for each 10-min decrease in walking distance between the fields and the river = 1.52, 95% confidence

Background: Buruli ulcer (BU) is a skin disease caused by Mycobacterium ulcerans. Its exact mode of transmission is not known. Previous studies have identified demographic, socio-economic, health and hygiene as well as environment related risk factors. We investigated whether the same factors pertain in Suhum-Kraboa-Coaltar (SKC) and Akuapem South (AS) Districts in Ghana which previously were not endemic for BU. Methods: We conducted a case control study. A case of BU was defined as any person aged 2 years or more who resided in study area (SKC or AS District) diagnosed according to the WHO clinical case definition for BU and matched with age-(+/-5 years), gender-, and community controls. A structured questionnaire on host, demographic, environmental, and behavioural factors was administered to participants. Results: A total of 113 cases and 113 community controls were interviewed. Multivariate conditional logistic regression analysis identified presence of wetland in the neighborhood (OR = 3.9, ...
Understanding disease ecology is vital in preventing future outbreaks of established infections and to predict the emergence of new pathogens. In recent decades there have been a number of high profile infectious diseases which have swept across countries and in some cases the world. Many of these begin as generalist emerging infections; such microbes are difficult to study in the wild due to their inherently ambiguous life histories and complex associations with numerous hosts and the environment. In this PhD a number of techniques are used to pinpoint and further understand the life history of one such pathogen Mycobacterium ulcerans, the causative agent of Buruli ulcer, in the hope that this data can be used to predict and prevent future outbreaks and can be applied to other emerging infections. The results of this study include the first identification of the pathogen in the environment for a whole new continent, South America. Further to this it has led to the discovery of the likely ...
This study examines some of the socioeconomic cost of treating 102 cases of Buruli ulcer between 1994 and 1996 at the St. Martin's Catholic Hospital in Agroyesum in the Amansie West district of the Ashanti region of Ghana. Seventy percent of the cases were children (up to 15 years of age). There was no sex difference in the distribution of cases. Hospitalization was prolonged (average = 186 days in 1994, 103 days in 1995, and 102 days in 1996) with no significant age and sex differences. There were 10 limb amputations, 12 patients were left with contracture deformities, one patient lost sight in one eye, and two died of sepsis and tetanus. The average total treatment cost per patient was $966.85 (62% indirect) in 1994, $706.08 (75% indirect) in 1995, and $658.74 (79% indirect) in 1996. With increasing number of cases, high treatment costs, and serious complications, urgent attention should be given to the disease in terms of control and research efforts aimed at early detection and treatment.
A flesh-eating bacteria is now reaching epidemic levels, spreading to 30 countries. Most cases of Buruli Ulcers come from sub-Saharan Africa, but Australia has dealt with the disease for years. While we know some methods to treat the disease, scientists are still unsure about its history or how to stop the spread.
Its the bug that has the scientific community baffled. Just what is causing the flesh-eating Buruli ulcer to march along Victorias coast towards Melbourne?
We report a case of Buruli ulcer in a tourist from the United Kingdom. The disease was almost certainly acquired in Brazil, where only 1 case had previously been reported. The delay in diagnosis highlights the need for physicians to be aware of the disease and its epidemiology.

Background Buruli ulcer is a serious individual skin disease due to species remains to be a matter of controversy, and relevant interventions to avoid this disease lack (we) the correct understanding of the life span history attributes in its organic aquatic ecosystem and (ii) immune system signatures that might be correlates of security. within a Buruli ulcerCendemic region (in the Republic of Benin, Western world Africa), we assayed sera gathered from either ulcer-free people or sufferers with Buruli ulcers for the titre of IgGs that bind to insect predator SGH, concentrating on those substances been shown to be maintained by colonies otherwise. IgG titres had been low in the Buruli ulcer individual group than in the ulcer-free group. Conclusions These data shall help framework potential investigations in Buruli ulcerCendemic areas, offering a rationale for analysis into individual immune system signatures of contact SAT1 with predatory aquatic pests, with special focus on those insect saliva ...
TY - JOUR. T1 - Paradoxical Reactions: Anti-Tumor Necrosis Factor Alpha Agents, Ustekinumab, Secukinumab, Ixekizumab, and Others. AU - Puig, Lluís. PY - 2017/1/1. Y1 - 2017/1/1. N2 - © 2018 S. Karger AG, Basel. Paradoxical reactions during treatment with a biologic agent can be defined as the appearance or exacerbation of a pathological condition that usually responds to this class of drug while treating a patient for another condition, which usually remains under control (even though there may be a change in morphology or phenotype). Paradoxical reactions were initially described as isolated case reports or case series in patients treated with anti-tumor necrosis factor (TNF) α agents, first in inflammatory rheumatic diseases, later in psoriasis and inflammatory bowel disease. Paradoxical reactions have subsequently been reported with other biological drugs or classes (e.g., tocilizumab), even though in some cases insufficient efficacy or phenotype switch may be difficult to differentiate ...
The pathogenesis of Buruli ulcers is thought to be essentially mediated by the production of mycolactone at the site of infection (6). The extensive tissue necrosis and minimal inflammation in Buruli ulcers constitute the hallmarks of these lesions, and reflect the cytocidal and immunosuppressive properties of this original macrolide (1). Mycolactone is able to diffuse rapidly within target cells, as shown by the cytosolic accumulation of fluorescent derivatives (31). Mycolactone then triggers diverse cytopathic effects, including cytoskeletal rearrangements and cell cycle arrest, eventually culminating in apoptotic/necrotic cell death (9). The manifestations and levels of mycolactone cytotoxicity vary extensively among cell types, suggesting that the molecular target of mycolactone may be differentially expressed or have different functions in different cells. At noncytostatic and cytotoxic concentrations, mycolactone displays immunomodulatory properties on human primary monocytes and dendritic ...
Non-tuberculous mycobacteria (NTM), particularly mycolactone producing mycobacteria (MPM), are bacteria found in aquatic environments causing skin diseases in humans like Buruli ulcer (BU). Although the causative agent for BU, Mycobacterium ulcerans has been identified and associated with slow-moving water bodies, the real transmission route is still unknown. This study aimed to characterize MPMs from environmental aquatic samples collected in a BU non-endemic community, Adiopodoumé, in Côte dIvoire. Sixty samples were collected in four types of matrices (plant biofilms, water filtrate residues, plant detritus and soils) from three water bodies frequently used by the population. Using conventional polymerase chain reaction (PCR), MPMs were screened for the 16S ribosomal RNA (rRNA) mycobacterial gene, the IS2404 insertion sequence, and MPM enoyl reductase (ER) gene. Variable Number Tandem Repeat (VNTR) typing with loci 6, 19, mycobacterial interspersed repetitive unit 1 (MIRU1) and sequence type 1(ST1

Results: Thirty-two of 156 (21%) patients developed paradoxical reactions a median 39 days (IQR 20-73 days) from antibiotic initiation. Forty-two paradoxical episodes occurred with 26 (81%) patients experiencing one and 6 (19%) multiple episodes. Thirty-two (76%) episodes occurred during antibiotic treatment and 10 (24%) episodes occurred a median 37 days after antibiotic treatment. The reaction site involved the original lesion (wound) in 23 (55%), was separate to but within 3 cm of the original lesion (local) in 11 (26%) and was more than 3 cm from the original lesion (distant) in 8 (19%) episodes. Mycobacterial cultures were negative in 33/33 (100%) paradoxical episodes. Post-February 2009 treatment involved more cases with no antibiotic modifications (12/15 compared with 11/27, OR 5.82, 95% CI 1.12-34.07, p = 0.02) and no further surgery (9/15 compared with 2/27, OR 18.75, 95% CI 2.62-172.73, p , 0.001). Six severe cases received prednisone with marked clinical improvement. On multivariable ...
My research interests concern the pathogens, Mycobacterium tuberculosis and M. ulcerans, in humans and experimental animal hosts. Studies in tuberculosis, principally in the mouse model, concern the response to chemotherapeutic agents, including novel compounds and novel combinations of drugs, and their modulation due to innate host factors and those involving the immune system after immunotherapeutic vaccination. Studies on M. ulcerans, the causative agent of Buruli ulcer, have focused on the differential response to vaccination in different mouse strains and the evaluation of novel chemotherapy regimens in comparison with the WHO standard of rifampin and streptomycin. We are also involved in studies to develop appropriate assays to detect mycolactone, the toxin that is the principal virulence factor of M. ulcerans.. ...
Approximately 1 billion people - one sixth of the worlds population - suffer from one or more neglected tropical diseases. The World Health Organization has defined Neglected Tropical Diseases as diseases that affect a majority of the developing world but have been underfunded in terms of research and product development dollars. They include (among others): Buruli ulcer, Chagas disease, Cholera, Dengue, Dracunculensis, Leishmaniasis, Onchocerciasis, Schistosomiasis, and Trachoma. Genomes for many of these pathogens are becoming available due to research efforts worldwide, and so the iCubed is collaborating with researchers to identify new epitopes and design vaccines using the CCHI funded iVAX toolkit. The iCubed runs a training session per year - following these training sessions, NTD researchers can gain access to a dedicated website containing their genomes of choice for their own epitope-mapping use.. ...

nuermbergerlab.com. The primary research focus in my laboratory is translational research related to the development of new drugs and regimens to improve the treatment of important mycobacterial infections, including tuberculosis (TB), Buruli ulcer and other diseases caused by nontuberculous mycobacteria. We approach the problem using both established and emerging animal and in vitro models of infection and relying on pharmacodynamic principles. Our major goal is to identify and optimize new drugs and drug combinations to shorten and/or simplify treatment and restrict the emergence of drug resistance. Over the past 18 years, we have worked with a variety of public and private sponsors and partners to inform the development of a number of new and repurposed drugs, including moxifloxacin, rifapentine, bedaquiline, pretomanid, sutezolid, and linezolid, as well as novel regimens containing these drugs. We continue to refine existing models and develop new models for pre-clinical drug efficacy ...
The immune response to mycobacterial infection is complex, involving several arms of the immune system. Organs are damaged by mycobacteria directly and also by the necrotic granulomatous immune response of the host to this pathogen. Ideally, mycobacterial infection is met with a balanced immune response that is sufficient to kill organisms but not so severe as to cause excessive tissue injury. Immunosuppression may promote growth of mycobacteria while decreasing tissue injury by the host response to the infection. Conversely, enhancement of the hosts immune response may kill more organisms but may also result in more organ damage.

Background: Basidiobolomycosis is a rare subcutaneous mycosis, which can be mistaken for several other diseases, such as soft tissue tumors, lymphoma, or Buruli ulcer in the preulcerative stage. Microbiological confirmation by PCR for and culture yield the most specific diagnosis, yet they are not widely available in endemic areas and with varying sensitivity. A combination of histopathological findings, namely, granulomatous inflammation with giant cells, septate hyphal fragments, and the Splendore-Hoeppli phenomenon, can confirm basidiobolomycosis in patients presenting with painless, hard induration of soft tissue.. Case Presentations: We report on three patients misdiagnosed as suffering from Buruli ulcer, who did not respond to Buruli treatment. Histopathological review of the tissue sections from these patients suggests basidiobolomycosis. All patients had been lost to follow-up, and none received antifungal therapy. On visiting the patients at their homes, two were reported to have died ...
Disease caused by Mycobacterium ulcerans. First described by MacCallum in 1948, but the name came from Buruli country in Uganda. The third most common Mycobacterium, that affected more than 30 countries.
Buruli ulcer (BU) is an emerging infectious disease that causes disfiguring skin ulcers. The causative agent, Mycobacterium ulcerans, secretes toxin called mycolactone that triggers inflammation and immunopathology. Existing treatments are lengthy and consist of drugs developed for tuberculosis. Here, we report that a pyrazolo[1,5-a]pyridine-3-carboxamide, TB47, is highly bactericidal against M. ulcerans both in vitro and in vivo. In the validated mouse model of BU, TB47 alone reduces M. ulcerans burden in mouse footpads by more than 2.5 log10 CFU compared to the standard BU treatment regimen recommended by the WHO. We show that mutations of ubiquinol-cytochrome C reductase cytochrome subunit B confer resistance to TB47 and the dissimilarity of CydABs from different mycobacteria may account for their differences in susceptibility to TB47. TB47 is highly potent against M. ulcerans and possesses desirable pharmacological attributes and low toxicity that warrant further assessment of this agent for

Eight adult patients (ages 18-58, 5 women) with Buruli ulcer (BU) confirmed by at least 2 diagnostic methods were seen in a 10-year period. Attempts to culture Mycobacterium ulcerans failed. Five patients came from jungle areas, and 3 from the swampy northern coast of Peru. The patients had 1-5 lesions, most of which were on the lower extremities. One patient had 5 clustered gluteal lesions; another patient had 2 lesions on a finger. Three patients were lost to follow-up. All 5 remaining patients had moderate disease. Diverse treatments (antituberculous drugs, World Health Organization [WHO] recommended antimicrobial drug treatment for BU, and for 3 patients, excision surgery) were successful. Only 1 patient (patient 7) received the specific drug treatment recommended by WHO. BU is endemic in Peru, although apparently infrequent. Education of populations and training of health workers are first needed to evaluate and understand the full extent of BU in Peru.
Background: While cultivation of pathogens represents a foundational diagnostic approach in the study of infectious diseases, its value for the confirmation of clinical diagnosis of Buruli ulcer is limited by the fact that colonies of Mycobacterium ulcerans appear only after about eight weeks of incubation at 30°C. However, for molecular epidemiological and drug sensitivity studies, primary isolation of M. ulcerans remains an essential tool. Since for most of the remote Buruli ulcer endemic regions of Africa cultivation laboratories are not easily accessible, samples from lesions often have to be stored for extended periods of time prior to processing. The objective of the current study therefore was to determine which transport medium, decontamination method or other factors decrease the contamination rate and increase the chance of primary isolation of M. ulcerans bacilli after long turnover time. Methods: Swab and fine needle aspirate (FNA) samples for the primary cultivation were collected ...
Author Summary Mycobacterium ulcerans is the causative agent of Buruli ulcer (BU), a destructive skin disease found predominantly in sub-Saharan Africa and south-eastern Australia. The mode of transmission and environmental reservoir remain unknown, but several studies have explored the role of aquatic insects, such as water bugs, and biting insects, such as mosquitoes. In the present study we investigated possible environmental source(s) of M. ulcerans in Victoria, Australia. Our results revealed that although M. ulcerans DNA could be detected at low levels in a variety of environmental samples, the highest concentrations of M. ulcerans DNA were found in the faeces of two species of possums, common ringtails and common brushtails. Possums are small arboreal marsupial mammals, native to Australia, and these particular species occur in both urban and rural areas. Examination and sampling of live captured possums in an area endemic for BU revealed that 38% of ringtail possums and 24% of brushtail possums,

Mycobacterium ulcerans [MU] produces mycolactone toxin when infected with a plasmid. Toxin is cytotoxic and immunosuppressive, causing extensive destruction of tissues, leading to large ulcers on exposed parts of the body. Spontaneous healing by secondary intention leads to contractures, subluxation of joints, disuse atrophy, distal lymphedema and other complications. The disease is endemic in some communities within the middle belt of Ghana. To document the clinical and epidemiological features of MU disease in the middle belt of Ghana and the outcome of treatment. Patients with lesions suspected to MU disease were screened by community workers. Lesions were confirmed by any of the following: direct smear examination, culture, polymerase chain reaction [PCR] , or histopathology. Patients were treated with rifampicin [10 mg/kg orally] and streptomycin [15 mg/kg IM] combination for eight weeks. Patients selected for surgical treatment included cases where medical treatment had failed, cases where ...
Mycobacterium ulcerans, the causative agent of Buruli ulcer (BU) disease, is unique amongst human pathogens in its capacity to produce a lipid toxin called mycolactone. While previous studies have demonstrated that bacterially-released mycolactone diffuses beyond infection foci, the spatiotemporal distribution of mycolactone remained largely unknown. Here, we used the zebrafish model to provide the first global kinetic analysis of mycolactones diffusion in vivo, and multicellular co-culture systems to address the critical question of the toxins access to the brain. Zebrafish larvae were injected with a fluorescent-derivative of mycolactone to visualize the in vivo diffusion of the toxin from the peripheral circulation. A rapid, body-wide distribution of mycolactone was observed, with selective accumulation in tissues near the injection site and brain, together with an important excretion through the gastro-intestinal tract. Our conclusion that mycolactone reached the central nervous system was
In most cases, experienced health professionals in endemic areas can make a reliable clinical diagnosis.. Depending on the patients age, the patients geographical area, the location of lesions, and the extent of pain experienced, other conditions should be excluded from the diagnosis. These other conditions include tropical phagedenic ulcers, chronic lower leg ulcers due to arterial and venous insufficiency (often in the older and elderly populations), diabetic ulcers, cutaneous leishmaniasis, extensive ulcerative yaws and ulcers caused by Haemophilus ducreyi1.. Early nodular lesions are occasionally confused with boils, lipomas, ganglions, lymph node tuberculosis, onchocerciasis nodules or other subcutaneous infections such as fungal infection.. In Australia, papular lesions may initially be confused with an insect bite.. Cellulitis may look like oedema caused by M. ulcerans infection but in the case of cellulitis, the lesions are painful and the patient is ill and febrile.. HIV infection is ...
Buruli ulcer (BU) is an infectious skin disease caused by Mycobacterium ulcerans. It mainly affects poor communities living close to bodies of water. In the absence of early treatment, this neglected disease can cause lasting deformities and may require limb amputation. It is reported in 34 countries and is the third most common mycobacterial disease in immunocompetent patients. Considerable progress has been made in treatment and prevention. The Cotonou Declaration (2009) describes the recommended control strategies. Although effective, current control strategies are limited because they do not take into account all the factors that influence emergence, prevention and cure of the disease. The control of Buruli ulcer mainly depends on intervention on social, cultural and psychosocial factors that influence preventive and self-care behaviour. The health promotion approach requires collaboration with populations in order to perform simultaneous actions on BU factors in the community setting. ...

Buruli ulcer (BU) is a neglected emerging infectious disease caused by Mycobacterium ulcerans. BU has become the third most prevalent mycobacteriosis worldwide, after tuberculosis and leprosy. Limited knowledge of the disease and the fact that it affects mainly poor rural communities contribute to underreporting of cases. Nevertheless, there are 6000 reported cases every year, of which more than 50% are children under the age of 15. For these reasons, the World Health Organization (WHO) has recognized BU as an emerging infectious disease with an important public health impact; that is both devastating for the individual and catastrophic for the economy of affected households.. M. ulcerans produces a dermonecrotic toxin, mycolactone, which induces extensive destruction of the skin and soft tissues with the formation of large ulcers, as well as bone and joint lesions. No specific vaccine is currently available for BU and because the disease progresses without pain or fever, treatment is frequently ...

BACKGROUND: Mycolactone is a macrolide produced by the skin pathogen Mycobacterium ulcerans, with cytotoxic, analgesic and immunomodulatory properties. The latter were recently shown to result from mycolactone blocking the Sec61-dependent production of pro-inflammatory mediators by immune cells. Here we investigated whether mycolactone similarly affects the inflammatory responses of the nervous cell subsets involved in pain perception, transmission and maintenance. We also investigated the effects of mycolactone on the neuroinflammation that is associated with chronic pain in vivo.

IFN-a: interferon alfa LTT: lymphocyte transportation test TNF-a: tumor necrosis factorealfa T umor necrosis factor alfa (TNF-a) antagonists are commonly used to treat inflammatory disorders and are considered particularly effective in the treatment of moderate to severe psoriasis. Paradoxically, however, new-onset occurrence orworsening of psoriasis has been increasingly recognized among patients treated with TNF-a antagonists. We report on a 60-year-old man who developed a severe psoriatic condition with diffuse alopecia during infliximab therapy for psoriasis, resulting in the discontinuation of infliximab. Lymphocyte transportation test (LTT) results were positive. Currently, there are few reports of LTTpositive cases that are related to paradoxical reactions by TNF-a antagonists. We discuss the relationship between paradoxical reaction and the mechanisms of LTT.
