The pneumococcal virulence factors include capsule, PspA, PspC, and Ply. Cytometric analysis demonstrated that the greatest levels of C3 deposition were on a Deltaply PspA(-) PspC(-) mutant. Also, Ply, PspA, and PspC expression resulted in C3 degradation in vitro and in vivo. Finally, blood clearance assays demonstrated that there was enhanced clearance of Deltaply PspA(-) PspC(-) pneumococci compared to the clearance of nonencapsulated pneumococci.
