This paper develops a population sequencing pipeline to estimate mutation rates in E. coli under varying population densities, finding a strong negative association between density and mutation rates.

This study identifies a reversible genetic mechanism in Salmonella Typhimurium that confers phage resistance by deleting the wzy locus, enabling recovery after phage predation.

The paper analyzes the population structure and evolution of Salmonella enterica serotype Typhi in Zimbabwe before a typhoid vaccine campaign, identifying dominant resistant genotypes and their AMR mechanisms.

The paper uses single-cell genomics to analyze bacterial population structures in antibiotic stress experiments, revealing sub-populations and resistance development not detectable with bulk sequencing.

This study constructs a phylogenetic tree of 131 S. Typhimurium strains to reveal population structure and adaptation to domesticated and wild animal hosts.
