Abstract

Using a novel porcine model of intravenous Streptococcus pneumoniae infection, we showed that invasive pneumococcal infections induce marked platelet activation and hyperreactivity. This may contribute to the vascular complications seen in pneumococcal infection.

Keywords: Infection; Myocardial infarction; Platelet activation; Platelets; Pneumonia; Streptococcus pneumoniae.
