Pherotypes of pneumococcal strains co-existing in healthy children.

Infection, genetics and evolution : journal of molecular epidemiology and evolutionary genetics in infectious diseases - 1 Oct 2011

Abstract excerpt

Genetic diversity in the species Streptococcus pneumoniae is mainly driven by horizontal gene transfer. S. pneumoniae is naturally competent for transformation. Competence is induced by a pheromone termed competence stimulating peptide (CSP) by a quorum-sensing mechanism. Two CSP pherotypes predominate amongst clinical isolates of S. pneumoniae, CSP-1 and CSP-2, with ability to trigger competence in bacteria of...
