Mycobacterium bovis, the causative agent of bovine tuberculosis, poses a significant zoonotic threat. This study defines the antibacterial activity and mechanism of the natural alkaloid isocorydine (ICD) against M. bovis using an integrated multi-omics approach. Phenotypic analyses demonstrated t...

Mycothiol (MSH) and ergothioneine (ERG) are thiols able to compensate for each other to protect mycobacteria such as Mycobacterium smegmatis against oxidative stress. Gamma-glutamylcysteine (GGC), another thiol and an intermediate in ERG biosynthesis has detoxification abilities. Five enzymes are in...

New strategies are required to reduce the worldwide burden of tuberculosis. Intracellular survival and replication of Mycobacterium tuberculosis after macrophage phagocytosis is a fundamental step in the complex host-pathogen interactions that lead to granuloma formation and disease. Greater underst...

Gene rv3722c of Mycobacterium tuberculosis is essential for in vitro growth, and encodes a putative pyridoxal phosphate-binding protein of unknown function. Here we use metabolomic, genetic and structural approaches to show that Rv3722c is the primary aspartate aminotransferase of M. tuberculosis...

Related surrogate species are often used to study the molecular basis of pathogenicity of a pathogen on the basis of a shared set of biological features generally attributable to a shared core genome consisting of orthologous genes. An important and understudied aspect, however, is the extent to whi...

Bovine tuberculosis (bTB), caused by Mycobacterium bovis (Mycobacterium tuberculosis complex), is a zoonotic disease that affects cattle and wildlife worldwide. In some regions of Spain, Iberian red deer (Cervus elaphus hispanicus) can serve as reservoir of infection, thus increasing the risk of hum...

In the present study, we applied microarray technology to define a biosignature from the whole genome expression in lung and spleen samples after BCG vaccination and M. bovis infection of BALB/c mice. The aims were two-fold, namely to define biosignatures that could predict vaccine success before ch...

In this report we demonstrated that under aerobic conditions, Mycobacterium bovis BCG expressing an hsp60-driven second copy of the hypoxia-related transcriptional regulator DosR increased 2-fold or greater the expression of 38 out of the 48 genes belonging to the DosR regulon, including the latency...
ORGANISM(S): Mycobacterium tuberculosis 
Mycobacterium tuberculosis infects a third of the world's population. Primary tuberculosis involving active fast bacterial replication is often followed by asymptomatic latent tuberculosis, which is characterised by slow or non-replicating bacteria. Reactivation of the latent infection involving a s...
ORGANISM(S): Mycobacterium bovis 
The goal of this study is to identify the different proteins secreted by Mycobacterium bovis in the culture media at different stages of bacterial growth. A field strain of M. bovis was allowed to grow in a culture media and culture supernatant was collected at three-time points representing approxi...
