Previous studies have shown that a purified hemagglutinin (25 kDa) from non-fimbriated Prevotella intermeda strain E18 is a protein-polysaccharide complex in nature. We attempted to clarify the relation between hemagglutinin, hemolysin and lecithinase produced by this strain. This 25 kDa protein showed hemolytic activity, but not lecithinase activity. Both hemagglutinating and hemolytic activities of this protein decreased by 50% with heat treatment at 50℃ for 10min, and were lost completely with treatment at 60℃ for 10min. Hemagglutinating activity was gradually lost over time, indicating that the 25 kDa protein contained hemagglutinin, hemolysin and protease.
