This study examines genetic diversity in the Vi capsule locus of Salmonella Typhi in Fiji, identifying convergent evolution of tviE mutations globally and highlighting the need for further functional analysis.

This study reanalyzes transposon sequencing data from 4 S. pyogenes genotypes across 9 phenotypic conditions to identify highly essential genes and operons, revealing differences in essentiality between in vivo and in vitro environments.

The paper shows extensive genomic overlap between Streptococcus pyogenes and Streptococcus dysgalactiae subsp. equisimilis, including shared genes and recombination events, with implications for vaccine development.
