This study examines capsule switching in Streptococcus pneumoniae using whole-genome sequences, finding that switching is limited to specific capsule-type pairs and influenced by genetic and ecological factors.

This study shows that enterococci reduce C. difficile sporulation through contact-dependent mechanisms involving surface pili, suggesting a role for gut microbiota in controlling spore formation.

This study investigates how phylogenetic and geographic factors constrain horizontal gene transfer in Streptomyces species, finding that core genome recombination is phylogenetically constrained while shell genes show geographic constraints.

The paper introduces fastGEAR, an algorithm for detecting both recent and ancestral recombination in bacterial populations, demonstrating its effectiveness on Streptococcus pneumoniae genomes.
