A variety of bacterial components has been known to induce platelet aggregation. Here, we report that Porphyromonas gingivalis lipopolysaccharide (Pg-LPS) caused direct aggregation of rabbit, but not human platelets. Pg-LPS also appeared to induce chemiluminescence response (CLR) in human polymorphonuclear neutrophils (PMNs) in whole blood or in serum. Human platelet aggregation was observed only in the PMN-platelet mixture system after stimulation with Pg-LPS.
