IncC plasmid genome rearrangements influence the vertical and horizontal transmission tradeoff in Escherichia coli

This study shows that IncC plasmid genome rearrangements enhance horizontal transmission while maintaining bacterial fitness, suggesting a strategy for plasmid dissemination.

Strain intrinsic properties and environmental constraints together shape Escherichia coli dynamics and diversity over a twenty-year human gut time series

This study tracks E. coli dynamics in a human gut over 20 years, showing how strain properties and environmental factors influence diversity and persistence.

Dissemination of IncI plasmid encoding blaCTX-M-1 is not hampered by its fitness cost in the pig's gut.

The study shows that an IncI plasmid encoding blaCTX-M-1 does not significantly reduce bacterial fitness in the pig gut, allowing its dissemination despite a minor growth rate difference.

The bacterial genetic determinants of Escherichia coli capacity to cause bloodstream infections in humans

This study identifies genetic determinants of Escherichia coli's ability to cause bloodstream infections using genomic and machine learning analyses of clinical isolates.

High pathogenicity island, aer and sit operons: a "menage a trois" in Escherichia coli extra-intestinal virulence

The paper shows that virulence in E. coli depends on the presence of the HPI, aer, and sit operons, with their co-occurrence and genomic location shaped by strain phylogeny.

Faecal carriage of ESBL-producing Escherichia coli in a remote region of Niger

The paper uses whole genome sequencing to analyze ESBL-E. coli carriage in rural Niger, finding high prevalence of CTX-M-15 with chromosomal and plasmid integration.

Interplay between bacterial clone and plasmid in the spread of antibiotic resistance genes in the gut: lessons from a temporal study in veal calves

The paper investigates how bacterial clones and plasmids spread antibiotic resistance genes in veal calves, finding that specific gene-plasmid-clonal combinations dominate due to efficient colonization and plasmid transfer.

Phylum barrier and Escherichia coli intra-species phylogeny drive the acquisition of resistome in E. coli

This study characterizes the resistome in 70,301 E. coli genomes, showing that phylogroup lineage and phylum barriers drive antibiotic resistance gene acquisition.
