Single-cell analysis of the interactions between Mycobacterium tuberculosis and macrophages

Mycobacterium Tuberculosis is a highly effective pathogen infecting nearly a third of the world's population. An M. tuberculosis infection starts when droplets containing bacteria enter an individual's lungs. The first host cells to contact the bacteria ar ...

FasR Regulates Fatty Acid Biosynthesis and Is Essential for Virulence of Mycobacterium tuberculosis

Stewart Cole, Claudia Sala

Mycobacterium tuberculosis, the etiologic agent of human tuberculosis, is the world's leading cause of death from an infectious disease. One of the main features of this pathogen is the complex and dynamic lipid composition of the cell envelope, which adap ...

Multicenter analysis of sputum microbiota in tuberculosis patients

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

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 ...

Genetics of human susceptibility to active and latent tuberculosis: present knowledge and future perspectives

Jacques Fellay, Nimisha Chaturvedi

Tuberculosis is an ancient human disease, estimated to have originated and evolved over thousands of years alongside modern human populations. Despite considerable advances in disease control, tuberculosis remains one of the world's deadliest communicable ...

Arylvinylpiperazine Amides, a New Class of Potent Inhibitors Targeting QcrB of Mycobacterium tuberculosis

Stewart Cole, Andrej Benjak, Anthony Vocat, Jérémie Piton, Shi-Yan Caroline Foo, Andréanne Lupien, Raphael Christopher Sommer

New drugs are needed to control the current tuberculosis (TB) pandemic caused by infection with Mycobacterium tuberculosis. We report here on our work with AX-35, an arylvinylpiperazine amide, and four related analogs, which are potent antitubercular agent ...

Optimized Background Regimen for Treatment of Active Tuberculosis with the Next-Generation Benzothiazinone Macozinone (PBTZ169)

Stewart Cole, Anthony Vocat, Shi-Yan Caroline Foo, Andréanne Lupien, Jean-Yves Gillon

The efficacy of the standardized four-drug regimen (comprising isoniazid, rifampin, pyrazinamide, and ethambutol) for the treatment of tuberculosis (TB) is menaced by the emergence of multidrug-resistant (MDR) and extensively drugresistant (XDR) strains of ...

New 1-hydroxy-2-thiopyridine derivatives active against both replicating and dormant Mycobacterium tuberculosis

Stewart Cole, Anthony Vocat

Tuberculosis (TB) treatment is confounded by the range of metabolic states displayed by Mycobacterium tuberculosis, by the long duration required and by the increasing prevalence of drug-resistant strains. Latent TB infection is especially difficult to tre ...

Rv3852 (H-NS) of Mycobacterium tuberculosis Is Not Involved in Nucleoid Compaction and Virulence Regulation

Stewart Cole, Claudia Sala, Andrej Benjak, Anthony Vocat, Gaëlle Séraphine Kolly, Andréanne Lupien, Nina Theres Odermatt

A handful of nucleoid-associated proteins (NAPs) regulate the vast majority of genes in a bacterial cell. H-NS, the histone-like nucleoid-structuring protein, is one of these NAPs and protects Escherichia coli from foreign gene expression. Though lacking a ...

Genomic and transcriptomic analysis of the streptomycin-dependent Mycobacterium tuberculosis strain 18b

Stewart Cole, Claudia Sala, Andrej Benjak, Ming Zhang, Swapna Uplekar, Jérémie Piton

Background: The ability of Mycobacterium tuberculosis to establish a latent infection (LTBI) in humans confounds the treatment of tuberculosis. Consequently, there is a need to discover new therapeutic agents that can kill M. tuberculosis both during activ ...

Stress and Host Immunity Amplify Mycobacterium tuberculosis Phenotypic Heterogeneity and Induce Nongrowing Metabolically Active Forms

John McKinney, Neeraj Dhar, Giulia Manina

Nonreplicating and metabolically quiescent bacteria are implicated in latent tuberculosis infections and relapses following "sterilizing" chemotherapy. However, evidence linking bacterial dormancy and persistence in vivo is largely inconclusive. Here we me ...
