The paper identifies SMiTE, a commensal-derived bacteriocin that effectively inhibits multiple Streptococcus pneumoniae serotypes without harming commensals.

This paper identifies and characterizes streptolancidin D, a bacteriocin in Streptococcus pneumoniae regulated by Rgg144/SHP144, which enhances intra-species competition and is effective against diverse isolates.

This study identifies bacteriocins in S. mitis that lyse S. pneumoniae, promoting DNA release and enhancing horizontal gene transfer in multispecies biofilms.

The paper identifies a non-functional variant of a bacterial communication system that rewires gene regulation to enhance stress adaptation and colonization in a globally successful Streptococcus pneumoniae lineage.

This paper shows that a commensal Streptococcus mitis strain prevents secondary pneumococcal pneumonia by inhibiting pneumococcal colonization and dissemination through bacteriocins.

The paper reconstructs the evolutionary histories of antibiotic-resistant pneumococcal lineages PMEN3 and PMEN9, showing how interspecies recombination contributes to antibiotic resistance and serotype switching.
