Heterologous expression of an immunogenic pneumococcal type 3 capsular polysaccharide in Lactococcus lactis.

abstract：:Streptococcus pneumoniae interacts with vascular endothelial cells during the course of bacteremia. In this study, we characterized the initial attachment of pneumococci to human endothelial cells (EC) and the response of the endothelium to this interaction. Pneumococci adhered to EC in a dose-dependent fashion. Attac...
