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.

In today’s Microbiome Digest the first interesting study comes not from bacteria but from virus domain. Examining the genomes within a sample from a wastewater treatment plant in Austria, Schulz et al. assembled a previously undiscovered giant virus genome with more genes encoding components of the protein translation machinery than in other giant viruses. The second highlighted  study introduces new oleaginous microalga as a new potential source of compounds for biotechnological applications.

Circadian clocks are ubiquitous timing systems that induce rhythms of biological activities in synchrony with night and day.In the first highlighted paper the authors present the structural basis of the day-night transition in a cyanobacterial circadian clock. The second highlighted paper evaluated the effects of antibiotic treatment on the honeybee gut microbiome. The authors found that exposure to antibiotics significantly alters the honeybee gut microbial community structure and leads to decreased survival.
