Synergistic inhibition of pneumococcal growth by Dolosigranulum pigrum and Corynebacterium pseudodiphtheriticum: insights into nasopharyngeal microbial interactions

30 May 2025

Abstract excerpt

ABSTRACT Streptococcus pneumoniae is a nasopharynx colonizer that can invade sterile tissues, causing invasive pneumococcal disease (IPD). Dolosigranulum pigrum and Corynebacterium pseudodiphtheriticum are commensal bacteria commonly isolated from the nasopharynx of healthy children, potentially playing a protective role. This study aims to analyze the effects of D. pigrum and C. pseudodiphtheriticum on S....
