    Comparative analysis of the Streptococcus pneumoniae competence development in vitro versus in vivo during pneumonia-derived sepsis by Sook Yin Chong, Shi Qian Lew, Tauqeer Alam, Christopher A. Gaulke, Gee W. Lau

    Published 2025-01-01
    “…IntroductionThe Streptococcus pneumoniae (pneumococcus) competence regulon is well-known for regulating genetic transformation but is also important for virulence. Some pneumococcal strains can enter a transient competent state for genetic transformation in an optimized competence-inducing medium when the threshold level of the peptide pheromone competence stimulating peptide is attained; upregulating the expression of three distinct phases of “early”, “late” and “delayed” competence genes. …”
