Gene expression patterns associated with multidrug therapy in multibacillary leprosy

Stewart Cole, Philippe Busso, Andrej Benjak, Charlotte Avanzi, Thyago Leal Calvo

Multidrug therapy (MDT) has been successfully used in the treatment of leprosy. However, although patients are cured after the completion of MDT, leprosy reactions, permanent disability, and occasional relapse/reinfection are frequently observed in patient ...

Leprosy in wild chimpanzees

Stewart Cole, Philippe Busso, Charlotte Avanzi

Humans are considered as the main host for Mycobacterium leprae(1), the aetiological agent of leprosy, but spillover has occurred to other mammals that are now maintenance hosts, such as nine-banded armadillos and red squirrels(2,3). Although naturally acq ...

Mycobacterium leprae diversity and population dynamics in medieval Europe from novel ancient genomes

Stewart Cole, Philippe Busso, Charlotte Avanzi

Background Hansen's disease (leprosy), widespread in medieval Europe, is today mainly prevalent in tropical and subtropical regions with around 200,000 new cases reported annually. Despite its long history and appearance in historical records, its origins ...

Emergence of Mycobacterium leprae Rifampin Resistance Evaluated by Whole-Genome Sequencing after 48 Years of Irregular Treatment

Stewart Cole, Philippe Busso, Andrej Benjak, Charlotte Avanzi

A case of Mycobacterium leprae rifampin resistance after irregular antile- prosy treatments since 1971 is reported. Whole-genome sequencing from four longi- tudinal samples indicated relapse due to acquired rifampin resistance and not to re- infection with ...

Population Genomics of Mycobacterium leprae Reveals a New Genotype in Madagascar and the Comoros

Stewart Cole, Philippe Busso, Pushpendra Singh, Stefanie Boy-Röttger, Andrej Benjak, Charlotte Avanzi, Thyago Leal Calvo

Human settlement of Madagascar traces back to the beginning of the first millennium with the arrival of Austronesians from Southeast Asia, followed by migrations from Africa and the Middle East. Remains of these different cultural, genetic, and linguistic ...

Multicenter analysis of sputum microbiota in tuberculosis patients

Stewart Cole, Claudia Sala, Jacques Rougemont, Philippe Busso, Marion Leleu, Andrej Benjak

The impact of tuberculosis and of anti-tuberculosis therapy on composition and modification of human lung microbiota has been the object of several investigations. However, no clear outcome has been presented so far and the relationship betweenM.tuberculos ...

British Red Squirrels Remain the Only Known Wild Rodent Host for Leprosy Bacilli

Stewart Cole, Philippe Busso, Charlotte Avanzi

Eurasian red squirrels (Sciurus vulgaris) in the British Isles are the most recently discovered animal reservoir for the leprosy bacteria Mycobacterium leprae and Mycobacterium lepromatosis. Initial data suggest that prevalence of leprosy infection is vari ...

Whole genome sequencing distinguishes between relapse and reinfection in recurrent leprosy cases

Stewart Cole, Philippe Busso, Pushpendra Singh, Chloé Marie Loiseau, Andrej Benjak, Charlotte Avanzi, Jérémie Piton

Background Since leprosy is both treated and controlled by multidrug therapy (MDT) it is important to monitor recurrent cases for drug resistance and to distinguish between relapse and reinfection as a means of assessing therapeutic efficacy. All three obj ...

Red squirrels in the British Isles are infected with leprosy bacilli

Stewart Cole, Philippe Busso, Chloé Marie Loiseau, Andrej Benjak, Charlotte Avanzi, Jérémie Piton

Leprosy, caused by infection with Mycobacterium leprae or the recently discovered Mycobacterium lepromatosis, was once endemic in humans in the British Isles. Red squirrels in Great Britain (Sciurus vulgaris) have increasingly been observed with leprosy-li ...

Transmission of drug-resistant leprosy in Guinea-Conakry detected by molecular epidemiological approaches

Stewart Cole, Philippe Busso, Chloé Marie Loiseau, Andrej Benjak, Charlotte Avanzi

Molecular drug susceptibility testing was performed on skin biopsies from 24 leprosy patients from Guinea-Conakry for the first time. We identified primary drug resistance in 4 cases and a dapsone-resistant cluster caused by the same strain. Primary transm ...

Insight into the evolution and origin of leprosy bacilli from the genome sequence of Mycobacterium lepromatosis

Stewart Cole, Philippe Busso, Pushpendra Singh, Andrej Benjak, Charlotte Avanzi

Mycobacterium lepromatosis is an uncultured human pathogen associated with diffuse lepromatous leprosy and a reactional state known as Lucio's phenomenon. By using deep sequencing with and without DNA enrichment, we obtained the near-complete genome sequen ...

Lansoprazole is an antituberculous prodrug targeting cytochrome bc1

Stewart Cole, Claudia Sala, Florence Pojer, Philippe Busso, Jan Lars Rybniker, Anthony Vocat, Andrej Benjak

Better antibiotics capable of killing multi-drug-resistant Mycobacterium tuberculosis are urgently needed. Despite extensive drug discovery efforts, only a few promising candidates are on the horizon and alternative screening protocols are required. Here, ...
