This study performs whole-genome sequencing of Lancefield group C/G streptococci isolates from Sheffield, UK, revealing high genomic diversity, antimicrobial resistance, and persistence within hosts.

This study shows that C. difficile can evolve vancomycin resistance through two pathways, but resistance comes with fitness costs and sporulation defects that may limit its clinical impact.

This study characterizes non-invasive Streptococcus pyogenes isolates from a 2022-23 UK scarlet fever upsurge, revealing strain diversity and genomic features associated with different infection types.
