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.

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.
