Adherence of Streptococcus sanguis

The presence of adhesins on the cell surface of S. sanguis enables the organism to grow and survive in the oral cavity. Many workers are now actively involved in attempting to characterise these adhesins and the molecular basis for adherence of various streptococci. The complexity of the adhesion processes is underlined by the many varied opinions as to the nature of the molecular components and biochemical interactions that are involved. Understanding the molecular mechanisms involved in bacterial adherence and in dental plaque formation will have significant impact on the prevention and treatment of oral diseases.
