The integration and degradation of viruses (or phages) constitute a genetic influx of genes within bacterial genomes (then named prophages). This process is thought to promote bacterial diversification. The mechanisms promoting the evolutionary impact of prophages on their hosts remain poorly understood. The first part of my thesis focused on the a...

Compared to bacteria of the gut microbiota, bacteriophages are still poorly characterized, and their physiological importance is far less known. Temperate phages are probably a major actor in the gut, as it is estimated that 80 % of intestinal bacteria are lysogens, i.e. they are carrying prophages. In addition, prophage induction rates are higher...
Shiga toxin (Stx)-encoding E. coli (STEC) strains are responsible for sporadic outbreaks of food poisoning dating to 1982, when the first STEC strain, E. coli O157:H7, was isolated. Regardless of STEC serotype, the primary symptoms of STEC infections are caused by Stx that is synthesized from genes resident on lambdoid prophage present in STEC. Des...
Identifying active prophages is critical for studying coevolution of phage and bacteria, investigating phage physiology and biochemistry, and engineering designer phages for diverse applications. We present Prophage Hunter, a tool aimed at hunting for active prophages from whole genome assembly of bacteria. Combining sequence similarity-based match...
The H‐NS‐like proteins MvaT and MvaU act coordinately as global repressors in Pseudomonas aeruginosa by binding to AT‐rich regions of the chromosome. Although cells can tolerate loss of either protein, identifying their combined regulatory effects has been challenging because the loss of both proteins is lethal due to induction of prophage Pf4 and...
Bacteriophages are widely recognised as rapidly evolving biological entities. However, in our exploration of ancient metagenomes, we discovered a genome nearly identical to present-day Mushuvirus mushu , a phage infecting commensal microorganisms in the human gut ecosystem. The DNA damage patterns of this genome have confirmed its ancient origin, a...
