Label-free optical vibrational spectroscopy to detect the metabolic state of M. tuberculosis cells at the site of disease [PDF]
, 2017 Tuberculosis relapse is a barrier to shorter treatment. It is thought that lipid rich cells, phenotypically resistant to antibiotics, may play a major role. Most studies investigating relapse use sputum samples although tissue bacteria may play an important role. We developed a non-destructive, label-free technique combining wavelength modulated Raman (

On the ability to reconstruct ancestral genomes from Mycobacterium genus [PDF]
arXiv, 2017 Technical signs of progress during the last decades has led to a situation in which the accumulation of genome sequence data is increasingly fast and cheap. The huge amount of molecular data available nowadays can help addressing new and essential questions in Evolution.

Using Capsule Neural Network to predict Tuberculosis in lens-free microscopic images [PDF]
arXiv, 2020 Tuberculosis, caused by a bacteria called Mycobacterium tuberculosis, is one of the most serious public health problems worldwide. This work seeks to facilitate and automate the prediction of tuberculosis by the MODS method and using lens-free microscopy, which is easy to use by untrained personnel.

A single regulator NrtR controls bacterial NAD+ homeostasis via its acetylation
eLife, 2019 Nicotinamide adenine dinucleotide (NAD+) is an indispensable cofactor in all domains of life, and its homeostasis must be regulated tightly. Here we report that a Nudix-related transcriptional factor, designated MsNrtR (MSMEG_3198), controls the de novo ...

Analysis of DevR regulated genes in Mycobacterium tuberculosis [PDF]
arXiv, 2013 The DevRS two component system of Mycobacterium tuberculosis is responsible for its dormancy in host and becomes operative under hypoxic condition. It is experimentally known that phosphorylated DevR controls the expression of several downstream genes in a complex manner.

Elusive preferred hosts or nucleic acid level selection? A commentary on: Evolutionary interpretations of mycobacteriophage biodiversity and host-range through the analysis of codon usage bias (Esposito et al. 2016) [PDF]
arXiv, 2016 While confirming the long held view that viruses do not closely imitate the use of their host's codon catalogue, Esposito and coworkers nevertheless consider it surprising that, despite having the ability to infect the same host, many mycobacteriophages share little or no genetic similarity (i.e.

Construction and Use of Transposon MycoTetOP2 for Isolation of Conditional Mycobacteria Mutants
Frontiers in Microbiology, 2020 Mycobacteria are unique in many aspects of their biology. The development of genetic tools to identify genes critical for their growth by forward genetic analysis holds great promises to advance our understanding of their cellular, physiological and ...
