TL;DR: An important adaptive role for metabolism diversification within group B2 and Shigella strains is found, but few or no extraint intestinal virulence-specific genes are identified, which could render difficult the development of a vaccine against extraintestinal infections.
Journal ArticleDOI

TL;DR: The MIUViG (Minimum Information about an Uncultivated Virus Genome) as mentioned in this paper standard was developed within the Genomic Standards Consortium framework and includes virus origin, genome quality, genome annotation, taxonomic classification, biogeographic distribution and in silico host prediction.
Journal ArticleDOI
UvrD helicase, unlike Rep helicase, dismantles RecA nucleoprotein filaments in Escherichia coli
Xavier Veaute,Stéphane Delmas,Marjorie Selva,Josette Jeusset,Eric Le Cam,Ivan Matic,Francis Fabre,Marie-Agnès Petit +7 more
TL;DR: It is shown that UvrD, but not Rep, directly prevents homologous recombination in vivo, and evidence that RecA contributes to toxicity in the rep uvrD mutant is provided.
Journal ArticleDOI
The MatP/matS Site-Specific System Organizes the Terminus Region of the E. coli Chromosome into a Macrodomain
Romain Mercier,Marie-Agnès Petit,Sophie Schbath,Stéphane Robin,Meriem El Karoui,Frédéric Boccard,Olivier Espéli +6 more
TL;DR: The results indicate that a specific organizational system is required in the Terminus region for bacterial chromosome management during the cell cycle, and the effects of MatP inactivation reveal its role as main organizer of the Ter macrodomain.
Journal ArticleDOI
Phages rarely encode antibiotic resistance genes: a cautionary tale for virome analyses
TL;DR: Findings provide guidance for documentation of ARG in viromes, and reassert that ARGs are rarely encoded in phage genomes, which were previously overestimated.
