Development and validation of a multiplex real-time qPCR assay using GMP-grade reagents for leprosy diagnosis

Stewart Cole, Charlotte Avanzi, Thyago Leal Calvo

Author summaryLeprosy is a chronic dermato-neurological disease caused by Mycobacterium leprae, an obligate intracellular bacterium. Diagnosis of leprosy often relies on skin examinations for clinical signs, bacilli staining from skin smears and invasive s ...

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 ...

Genomic Characterization of Mycobacterium lepraeto Explore Transmission Patterns Identifies New Subtype in Bangladesh

Stewart Cole, Andrej Benjak, Charlotte Avanzi

Mycobacterium leprae, the causative agent of leprosy, is an unculturable bacterium with a considerably reduced genome (3.27 Mb) compared to homologues mycobacteria from the same ancestry. In 2001, the genome ofM. lepraewas first described and subsequently ...

Understanding the Reconstruction of Personal Networks Through Residential Trajectories

Vincent Kaufmann, Gil Viry, Guillaume Simon Joseph Drevon

This article examines how residential trajectories influence the spatiality and composition of personal networks. Three mechanisms are considered: the addition of spatially close network members, the selection of spatially distant network members, and the ...

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 ...

Highly Reduced Genome of the New Species Mycobacterium uberis, the Causative Agent of Nodular Thelitis and Tuberculoid Scrotitis in Livestock and a Close Relative of the Leprosy Bacilli

Stewart Cole, Andrej Benjak, Charlotte Avanzi

Nodular thelitis is a chronic enzootic infection affecting dairy cows and goats. The causative agent was recently shown to be related to the leprosy-causing bacilli Mycobacterium leprae and Mycobacterium lepromatosis. In this study, the genome of this path ...

Genomics: a Swiss army knife to fight leprosy

Charlotte Avanzi

Leprosy, a highly disabling and stigmatizing infectious disease, is caused by Mycobacterium leprae and the newly discovered agent, Mycobacterium lepromatosis. Though treatable with antibiotics, leprosy has still not been eradicated, and around 200,000 new ...

Antimicrobial resistance in leprosy: results of the first prospective open survey conducted by a WHO surveillance network for the period 2009-15

Stewart Cole

Objectives: Antimicrobial resistance (AMR) is a priority for surveillance in bacterial infections. For leprosy, AMR has not been assessed because Mycobacterium leprae does not grow in vitro. We aim to obtain AMR data using molecular detection of resistance ...

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 ...

Mycobacterium lepromatosis Infections in Nuevo Leon, Mexico

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

The frequency of infection caused by the recently described pathogen Mycobacterium lepromatosis is unknown. Here, we describe the demographics, clinical characteristics, and therapeutic outcomes of five lepromatous leprosy patients suffering from M. leprom ...

Zoonotic Leprosy in the Southeastern United States

Stewart Cole, Pushpendra Singh, Rahul Sharma

Nine-banded armadillos (Dasypus novemcinctus) are naturally infected with Mycobacterium leprae and have been implicated in zoonotic transmission of leprosy. Early studies found this disease mainly in Texas and Louisiana, but armadillos in the southeastern ...

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 ...

How much does it cost? Optimization of costs in sequence analysis of social science data

Philipp Bucher

One major methodological problem in analysis of sequence data is the determination of costs from which distances between sequences are derived. Although this problem is currently not optimally dealt with in the social sciences, it has some similarity with ...
