Host stress hormone norepinephrine stimulates pneumococcal growth, biofilm formation and virulence gene expression

Abstract excerpt

BACKGROUND: Host signals are being shown to have a major impact on the bacterial phenotype. One of them is the endogenously produced catecholamine stress hormones, which are also used therapeutically as inotropes. Recent work form our laboratories have found that stress hormones can markedly increase bacterial growth and virulence. This report reveals that Streptococcus pneumoniae, a commensal that can also be a...
