Haemolysis of human erythrocytes by the Fusobacterium nucleatum associated with periodontal disease.

摘要: Fusobacterium nucleatum and Bacteroides gingivalis are associated with oral disease. They both attach to haemagglutinate human erythrocytes. Experiments were performed determine whether haemolysis would occur following attachment of strains F. species including B. gingivalis. The consistently displayed haemagglutination haemolytic activity. other but no measurable Varying the concentration whole cells in standard assay suggested a nucleatum-erythrocyte binding site interaction. moiety was observed various cell, cell wall lipopolysaccharide extracts.
