This study characterizes the global population structure and genetic diversity of serotype 12F Streptococcus pneumoniae, identifying strand-slippage mutations as a mechanism for capsule variation and vaccine evasion.

This study shows that pneumococcal colonization in infant mice enhances and prolongs anti-viral immune responses to PVM infection compared to viral infection alone.

This paper introduces SeroBA(v2.0), a tool for pneumococcal serotyping, and SeroBAnk, a resource for capsular diversity, which accurately identifies 102 serotypes and supports community contributions for updates.

The paper examines persistence of vaccine serotypes of Streptococcus pneumoniae in Mongolia after PCV13 introduction, finding changes in lineage composition, virulence, and drug resistance.
