Promiscuous signaling by a regulatory system unique to the pandemic PMEN1 pneumococcal lineage.
Streptococcus pneumoniae (pneumococcus) is a leading cause of death and disease in children and elderly.Genetic variability among isolates from this species is high.These differences, often the product of gene loss or gene acquisition via horizontal gene transfer, can endow strains with new molecular pathways, diverse phenotypes, and ecological adv
