ProteomicsRv0180c contributes to M. tuberculosis cell shape and to infectivity in mice and host cells
Mycobacterium tuberculosis, the main causative agent of human tuberculosis, is transmitted from person to person via small droplets containing very few bacteria. Optimizing the chance to seed in the lung is therefore a major adaptation to favor survival and dissemination in the human population. He...

GenomicsThe PhoP-dependent ncRNA Mcr7 modulates the TAT secretion system in Mycobacterium tuberculosis [ChIP-Seq]
The PhoPR two-component system is essential for virulence in Mycobacterium tuberculosis where it controls expression of approximately 2% of the genes, including those for the ESX-1 secretion apparatus, a major virulence determinant. Mutations in phoP lead to compromised production of pathogen-specif...

TranscriptomicsRNA-seq and genome-wide CRISPRi and Tn-seq analyses of BVL3572S-treated Mycobacterium tuberculosis H37Rv
(i) RNA-seq of M. tuberculosis H37Rv cultures grown in the presence of BVL3572S for 6 h compared to untreated controls. (ii) Genome-wide M. tuberculosis H37Rv CRISPRi libraries were grown in the presence of ATc for 5 days prior to drug exposure. Cultures were treated with sub-MIC BVL3572S concentra...

GenomicsWhole genome sequencing of spontaneous resistant mutants of Mycobacterium tuberculosis H37Rv selectec in the presence of BVL3572S and amino acids
M. tuberculosis H37Rv cultures were exposed to BVL3572S in the absence or presence of L-histidine or L-alanine for at least 4 weeks. Individual colonies were picked and their genomic DNA extracted, indexed, and sequenced.

TranscriptomicsEvolutionary conserved mutations in PhoPR attenuate the virulence of animal-adapted tuberculosis strains for humans
By genome comparison of 30 MTBC strains, we identified three SNPs affecting the phoPR genes of members of the animal and M. africanum lineages that were not seen in the M. tuberculosis sensu-stricto genomes. The genes phoPR encode a two component regulatory system that is known for its strong impact...
