Bacterial Adherence Related to Agglutination and Surface Film Formation
Secretory antibodies to oral bacteria may act by preventing microbial colonization of teeth and mucosal surfaces (1). During colonization, many processes are potentially susceptible to interference by antibodies: sorption of a cell to the surface; attachment of the cell by extraneous, e.g., salivary, polymers; production by the cell of extracellular materials such as glucans and teichoic acids. In vitro tests have documented the effect of antibodies in inhibiting adherence dependent on glucan production (2). Moreover, secretory antibodies may interfere with the sorption of oral bacteria to cheek cells (3). Similarly, we have previously demonstrated that components of oral fluids may impair the attachment of streptococci to the acquired pellicle on teeth in vitro, and a complex relationship between adherence and agglutination was observed (4). Since antibodies (3) and other secretory products (4) may cause agglutination as well as adherence inhibition, further studies on the relationship between these two phenomena seemed indicated. The present paper also deals with some aspects of the effect of surface film formation on bacterial adherence.
