Human C-reactive protein (CRP) increases survival of and decreases bacteremia in mice infected with Streptococcus pneumoniae. Such protection of mice against pneumococcal infection is seen only when CRP is administered into mice 6 hours before to 2 hours after the injection of pneumococci, but not when CRP is given to mice at a later time. Our first aim was to define the mechanism of CRP-mediated initial protection of mice against infection. It was proposed that CRP binds to phosphocholine (PCh) moieties present in the cell wall and activates the complement system on the pneumococcal surface that kills the pathogen. …
