Gut microbiome focus: Differences in the gut microbiome between children and adults can mediate the metabolism of arsenic possibly leading to differences in exposure risk, the gut microbiome’s ability to protect against salmonella infection is dependent on the IFNy producing bacteria, the microbiome of insoluble fibre is characterized, and a new in vitro technique to interrogate intestinal transport of microbiota and antigens. Plus an overview of the world data centre for microorganisms, and MicroScope for microbial genome annotation.

Highlighted articles today bring some interesting news about bacteria. in the first one study of Lebreton et al. shed light on the evolutionary history of pathogens, which evolved nearly indestructible properties and have become leading causes of modern antibiotic-resistant infections in hospitals. In the second highlighted article Schnettger et al. discover a natural mechanism by which our cells kill the bacterium responsible for tuberculosis (TB)  – without the use of antibiotics, meaning that even antibiotic-resistant
strains could be eliminated.
