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 ...

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 ...
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.

Quashigah (Rtd), opened the course under the chairmanship of Nana Kwame Akuoko Sarpong, Paramount Chief of Agogo Traditional Council. The main objective of the course was to train doctors working in endemic areas to improve their capacities to manage of Buruli ulcer and its complications. Those trained will support their national programmes to train health workers in their respective countries in a standardized manner. It ...
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.
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 ...
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.. ...

The primary research focus in my laboratory is translational research related to TB drug development. Using established animal and in vitro models of active and latent TB infection and relying on pharmacodynamic principles, our major goal is to identify and optimize new drugs and drug combinations to shorten and/or simplify TB treatment and restrict the emergence of drug resistance. Over the past 15 years, our work has informed the development of a number of new and repurposed drugs, including moxifloxacin, rifapentine, bedaquiline, PA-824, and the oxazolidinones sutezolid and linezolid, as well as novel combinations containing these drugs. We continue to refine existing models and develop new models for pre-clinical drug efficacy studies, including murine models of cavitary TB and a flow-controlled in vitro system for studying the pharmacodynamics of new drugs and combinations. A second research interest is applying similar approaches to improve the treatment of Buruli ulcer, an emerging yet ...
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 ...

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,

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 ...
The Buruli ulcer disease mainly affects children under the age of 15, the reason for which is unknown and no research has been conducted about this, nor indeed into the methods of infection of this rare disease.In Africa, DAHW,Germany in partnership with Ludwig Maximilian University of Munich, the Bernhard Nocht Institute for Tropical Medicine in Hamburg and long term partner Fondation Follereau Luxembourg (FFL)is working to achieve better diagnosis for patients and to finally find the causes of Buruli Ulcer..

A family of toxins produced by Mycobacterium ulcerans; strains from different geographic areas produce distinct patterns of mycolactone congeners. Mycolactone has significant immunosuppressive effects and inhibits production of macrophage inflammatory protein (MIP-1α), MIP-1β, RANTES, interferon-γ-inducible protein 10, and monocyte chemoattractant protein 1, but not IL-12, TNFα, or IL-6. See Buruli ulcer. ...
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 ...
In the case of non-ulcerative plaque lesions, we observed in half of all patients either an enlargement or ulceration of lesions during antibiotic therapy. Histopathological analysis after completion of antibiotic treatment revealed the persistence of extensive necrotic areas besides hallmarks of successfully treated BU lesions, like infiltration, granuloma formation and loss of solid staining of the mycobacteria. Where removal of the necrotic tissue by the immune system is not efficient enough, lesions are ulcerating, leading to the discharge of necrotic tissue. Based on the clinical and histopathological data it is suggested to support healing of such plaque lesions by surgical débridement. While our data demonstrate that the antibiotic therapy efficiently destroys M. ulcerans infection foci, they also indicate that proper wound management during and after chemotherapy is for advanced BU lesions as important as the antibiotic treatment itself ...

Anyone have a dog thats experienced a paradoxical reaction to Xanax? Today I learned that Button, apparently, is one of the small percentage of dogs that become extremely excited and hyper on the stuff ... hes taken it before, but I never remembered him having any negative response to it. Last time we were at the vet, they gave us a slightly higher dose to use before we visit the office because were trying to make the vets office a bit less horrifying for him. So I gave him the meds, waited half an hour, put him in the car and we got there, and instead of being relaxed, he was pumped. Totally into everything and more interested in the dogs and people than usual ... it was sort of weird, but not that dramatic until we got home. From about 2 PM until 4, it was like Button was on cocaine.

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.
Scientists in Australia have voiced concern about an apparent outbreak of Buruli ulcer, a flesh-eating disease that usually occurs in West and central Africa.
For example, in the recently held meeting of the Disease Reference Group (DRG) for Research on Tuberculosis (TB), Leprosy and Buruli Ulcer, leprosy group was invited to a one day activity in a 3-day meeting wherein TB had the full agenda. We are just lucky that Dr Diana Lockwood was there, otherwise, no other leprosy expert was around to discuss with us. I do appreciate though the support I am getting from Dr Steve Lyons as far as multi-drug therapy drug supply is concerned but even if there is a Global NTD meetings, leprosy programme is not equally represented, from our end it is the Filaria programme which is given priority and called upon on these meetings ...

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.

Bacteriophages, or phages, are viruses that infect bacteria. Mycobacteriophages are bacteriophages that specifically infect the genus Mycobacterium. This genus of bacteria includes human pathogens such as Mycobacterium tuberculosis, Mycobacterium leprae and Mycobacterium ulcerans, which cause tuberculosis, leprosy and Buruli ulcer, respectively. The full genome sequences of 654 mycobacteriophages are currently available. Collectively, these 654 phages encode 69,581 genes. Only 20.25% of these genes have at least one known homologue in NCBI, the National Center for Biotechnology Information, leaving roughly 80% of all known mycobacteriophage genes without even a predicted function. Bacteriophages are highly host-specific and typically only infect a small number of bacterial hosts. The host range of 204 mycobacteriophages, initially isolated on Mycobacterium smegmatis strain mc2 155, was recently determined on three other bacterial hosts: M. tuberculosis and two M. smegmatis strains, Jucho and MKD8. The
This case demonstrates that successful treatment of M. ulcerans osteomyelitis and septic arthritis can be achieved with limited surgical debridement and 6 months of oral rifampicin and ciprofloxacin; this is, to the best of the authors knowledge, the first time that this has been reported. Our patients osteomyelitis progressed radiologically despite initial surgical debridement, but then resolved following the commencement of rifampicin and ciprofloxacin without further surgery, and with no local or distal recurrences in the 36-month follow-up period. Thus, we believe that this combination of antibiotics resulted in cure of the osteomyelitis in our case, and prevented the development of further metachronous M. ulcerans lesions. This raises the possibility that this simple and well-tolerated oral combination has the potential to reduce significantly the morbidity and disability that results worldwide in the surgical treatment of M. ulcerans osteomyelitis, and warrants further study.. M. ...
Tropical ulcer, more commonly known as jungle rot, is a chronic ulcerative skin lesion thought to be caused by polymicrobial infection with a variety of microorganisms, including mycobacteria. It is common in tropical climates. Ulcers occur on exposed parts of the body, primarily on anterolateral aspect of the lower limbs and may erode muscles and tendons, and sometimes, the bones. These lesions may frequently develop on preexisting abrasions or sores sometimes beginning from a mere scratch. The vast majority of the tropical ulcers occur below the knee, usually around the ankle. They may also occur on arms. They are often initiated by minor trauma, and subjects with poor nutrition are at higher risk. Once developed, the ulcer may become chronic and stable, but also it can run a destructive course with deep tissue invasion, osteitis, and risk of amputation. Unlike Buruli ulcer, tropical ulcers are very painful. Lesions begin with inflammatory papules that progress into vesicles and rupture with ...
The chances are that if you turn on your television or scan your local news sources, you will hear about infectious diseases like HIV/AIDS, Ebola, Tuberculosis, Hepatitis and Measles. Now, can you say the same for Buruli ulcers? How about Guinea Worm disease? Chagas disease? Yaws or Schistosomiasis? Your response might not be as certain.. This is not because the diseases only infect a few people each year or are not as dangerous. Actually, combined, these diseases categorized as Neglected Tropical Diseases (NTDs) impact more than one billion people every year [1]. According to the World Health Organization (WHO), NTDs include communicable diseases that exist in tropical and subtropical climates of nearly 150 countries, and mostly impact those living in poverty with close proximity to infectious vectors [1]. The WHO has created a roadmap to treat, prevent and eliminate the burden of NTDs, which includes five strategies of control: Preventative chemotherapy; Vector and intermediate host control; ...
Dear Sir,. Paradoxical worsening in tuberculosis is an exuberant inflammatory reaction characterised by clinical or radiological worsening after initiation of antitubercular therapy in the absence of disease relapse or presence of another diagnosis.1 With no defined diagnostic criteria, this entity is diagnosed purely clinically after ruling out drug resistance, poor drug compliance and disease relapse. Described prevalence is varied across literature ranging from 2.3% to 23%.2 ,3 We here did a retrospective chart review of patients with tuberculous lymphadenitis to determine the incidence of this phenomenon and also to determine the clinical and laboratory risk factors for the same. Description of this entity in Indian literature has been scarce and … ...

Introduction: Pyoderma gangrenosum (PG) is a rare inflammatory disorder with an incidence of 0.63 per 100,000 person years1 . It is a sterile inflammatory neutrophilic dermatosis2,5, associated with recurrent cutaneous ulcerations with mucopurulent or haemorrhagic exudate. The peak age of incidence is from 20 to 50 with a female preponderance2,3. Although the lower legs are common sites for PG, other sites including breast, hand, trunk and peristomal skin have been reported2 .. Case Presentation: A 36 year old waiter was referred to the dermatology outpatient clinic in 2011 with an 18 month history of non-healing ulcer of his right malleolus measuring 2cm in diameter sustained post trauma. Differential diagnoses included Buruli ulcer and Madura foot. MRI scans excluded osteomyelitis. Biopsies of several sites including the skin of the tibial malleolus and posterior aspect of the ankle revealed necrosis of the underlying dermis and deep tissue. Stains for fungi and Acid Fast Bacilli were ...
Summary: The authors describe and analyze management in the Murray-Darling basin of Australia, long regarded as a model for integrated river basin management. This interior basin of over 1 million km2 in semi-arid southeastern Australia is defined by the catchment areas of the Murray and Darling Rivers and their tributaries. Water management issues include allocation, quality, and dryland salinity. Because of Australias federal governmental structure, institutional development has been more a matter of integrating state and local endeavors than decentralization of national authority. The Australian national government has little constitutional power over water resources. The five states in the basin make policy regarding water rights, discharge permits, fees, and the construction and operation of physical structures. River management began on the Murray River in the 1920s under the terms of a tri-state agreement. As the scope of management widened to the entire basin, more states were added and ...
Firefighters raced to contain massive bushfires in southeastern Australia Tuesday, taking advantage of a brief drop in temperatures and some much-needed rainfall before another heatwave strikes later this week.
This species is found in the Southwestern Pacific. It is widely distributed in cool tropical and warm temperate waters of the southern Pacific. It is known so far from off southeastern Australia, Lord Howe Island (Francis 1991), Norfolk Island, New Zealand, the Kermadec Islands (Francis et al. 1987), Rapa and Easter Island. Future collecting will likely reveal B. unimaculatus to occur at intermediate island localities. It is also reliably reported in the literature as far north as Noosa, Queensland in eastern Australia (Grant 1978) and has been collected in Port Phillip Bay, Victoria in the south ...

In patients with depression, a possibility for suicide should be borne in mind; benzodiazepines should not be used in such patients without adequate anti-depressant therapy.. Lorazepam should be used with caution in patients with compromised respiratory function (e.g. COPD, sleep apnea syndrome).. Elderly or debilitated patients may be more susceptible to the sedative effects of Lorazepam. Therefore these patients should be monitored frequently and have their dosage adjusted carefully according to patient response; the initial dosage should not exceed 2 mg.. Paradoxical reactions have been occasionally reported during benzodiazepine use. Such reactions may be more likely to occur in children and the elderly. Should these occur, use of the drug should be discontinued.. The usual precautions for treating patients with impaired renal or hepatic function should be observed. As with all benzodiazepines, the use of lorazepam may worsen hepatic encephalopathy; therefore, lorazepam should be used with ...

Most clinical strains of Pseudomonas aeruginosa, a leading agent of nosocomial infections, are multiresistant to antibiotherapy. Because of the paucity of new available antibiotics, the investigation of strategies aimed at limiting the action of its major virulence factors has gained much interest. The type 3 secretion system of P. aeruginosa and its effectors are known to be major determinants of toxicity and are required for bacterial dissemination in the host. Bacterial transmigration across...

Abstract We conducted a literature review based on current scientific articles and practice experiences to summarize information and guidance principles to make these following suggestions to health care practitioner: Before commencing BU treatment and before starting ART, all HIV/MU co-infected patients should be actively screened for tuberculosis. BU treatment should be commenced before commencing ART and provided for 8 weeks duration. And for the common sense, based on TB management experience HIV, TB and BU control programs should work together in a cooperative framework, mainly in tropical and subtropical regions where the prevalence of these 3 diseases seems high. As, HIV/BU co-infection is increasing in tropical regions, more study should be initiated to determine the cumulative effect of IRIS and paradoxical reactions in BU/HIV co-infected patients on ART and anti-mycobacterial agents, in order to set up recommendation as it was done in TB/HIV co-infection for proper management ...
A 20-year-old female patient presented with swelling and pain in the neck, difficulty in opening her mouth, dyspnea, nausea, fever, and shivering. She was prescribed amoxicillin for one week due to a teeth infection and had lower molar tooth extraction on the same side two days before. Neck examination showed a swelling, 2x3 cm in size, in the carotid triangle and minimal hyperemia on the skin. A diagnosis of internal jugular venous thrombophlebitis was made and parenteral antibiotherapy was administered along with antithrombotic therapy. Complete improvement was observed after 15 days and the patient was symptomless in the eighth month. ...

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecules storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters. ...

Background: Toxigenic Corynebacterium ulcerans can cause a diphtheria-like illness in humans and have been found in domestic animals, which were suspected to serve as reservoirs for a zoonotic transmission. Additionally, toxigenic C. ulcerans were reported to take over the leading role in causing diphtheria in the last years in many industrialized countries. Methods: To gain deeper insights into the tox gene locus and to understand the transmission pathway in detail, we analyzed nine isolates derived from human patients and their domestic animals applying next generation sequencing and comparative genomics. Results: We provide molecular evidence for zoonotic transmission of C. ulcerans in four cases and demonstrate the superior resolution of next generation sequencing compared to multi-locus sequence typing for epidemiologic research. Additionally, we provide evidence that the virulence of C. ulcerans can change rapidly by acquisition of novel virulence genes. This mechanism is exemplified by an ...

Paradoxical reactions such as acute hyperexcited states, anxiety, hallucinations, increased muscle spasticity, insomnia, rage, sleep disturbances and stimulation have been reported; should these occur, use of the drug should be discontinued. Minor changes in EEG patterns, usually low-voltage fast activity, have been observed in patients during and after diazepam therapy and are of no known significance ...
Maximum temperatures averaged across Australia for September were 0.92 °C warmer than usual. Daytime temperatures averaged across southeastern Australia were particularly warm, ranking as the sixth warmest on record, with Victoria observing its fifth warmest September for daytime temperatures and Tasmania its warmest September maxima since 2001. South Australia also had its 8th warmest September daytime temperatures. Maximum temperatures along the southern half of Australia were generally 1 to 3 °C above average, except for the southwest of WA. A small region experienced maxima up to 4 °C warmer than usual stretching from Port Augusta in South Australia to the central New South Wales border. A large area spanning eastern South Australia, the western half of both Victoria and New South Wales, and northern Tasmania, as well as southeast WA, recorded daytime temperatures in the highest 10% of records. The more notable below average temperatures were recorded in the Kimberley region of WA, with ...
What causes ulcer? Everybody wants to know that. Any medical man who might happen to read this will probably sneer when he arrives this far, and he will feel very superior because he is aware that no one knows the cause of ulcer.. Perhaps not, but we can make a reasonable guess at it. What is an ulcer anyhow? Ulcers occur elsewhere on the body and there is no reason to suppose that ulcer of the stomach is different from any other sort of ulcer.. An ulcer is a solution of continuity on a mucous membrane. Ulcers of the skin are caused by varicose veins: one cause of ulcer, then, is sluggishness of the circulation. Another form of skin ulcer perforating ulcer of the sole of the foot is caused by the plugging of an artery. Ulcers may be caused by destruction of tissue from chemicals. Ulcers, such as those of the cornea of the eye, are caused by infection.. Applying these to peptic ulcer, sluggish venous circulation cannot be demonstrated near peptic ulcer, so it may be discarded as a cause. Plugging ...
