Streptococcus pneumoniae (pneumococcus) is a prevalent human pathogen responsible for a variety of diseases, including pneumonia, bacteremia, sepsis, meningitis and otitis media, with a death toll of >22,000 a year in the United States alone. Pneumococcus utilizes the competence regulon and its associated signaling peptide, the competence stimulating peptide (CSP), to initiate its attack on the host and establish an infection. In this work, we set to: 1) develop a pan-group QS inhibitor that can effectively interact with both the pneumococcus ComD1 and ComD2 receptors; and 2) evaluate the utility of dominant-negative CSPs (dnCSPs) in attenuating pneumococcus infectivity. Our results highlight the potential of inhibiting the competence regulon as a therapeutic approach to combat pneumococcus infections. Administration of a dominant-negative competence stimulating peptide (dnCSP) two-hour post-infection resulted in attenuation of Streptococcus pneumoniae infectivity and increased survival in a mouse model of acute pneumonia.
