This study analyzes 585 Streptococcus canis isolates to identify genetic factors driving its expansion, finding two dominant lineages associated with increased pathogenicity and host adaptation through genetic exchange with other streptococcal species.

This study evaluates nanopore adaptive sampling for enriching low-abundant bacterial plasmids, showing improved assembly quality and reduced sequencing time.

This paper uses adaptive laboratory evolution to replace tryptophan in E. coli with a synthetic analog, revealing that stress response inhibition, not translation rigidity, limits genetic code expansion.

This study identifies host-specific genetic determinants in E. coli using genome-wide association, revealing lineage-specific adaptations to human, cattle, chicken, and pig hosts.

This study tracks genetic diversity of Mycobacterium abscessus in CF patients over time, finding non-clonal evolution and accumulation of mutations in virulence and resistance genes.

The paper identifies host-specific genetic variants in Campylobacter jejuni genomes from Germany and Canada, showing associations between genome characteristics and host adaptation.

The paper characterizes the genomic diversity of multi-drug resistant Escherichia coli in wastewater, finding high genetic variation and resistance/virulence genes.
