Glycosyltransferases (GTF) are an indispensable element for the proper functioning of S. mutans.In the early phase of biofilm development, S. mutans are bound to the teeth surface. It is thought that this binding is the first step in the formation of plaque

Streptococcus mutans (S. mutans) has important virulence factors related to the etiology and pathogenesis of dental caries.

Streptococcus mutans (S. mutans) is one of the bacteria often associated with caries, due to its ability in producing acid and forming the biofilm for bacterial colonisation on the surface of oral cavities. In addition to S. mutans, Streptococcus sobrinus (S. sobrinus) bacteria are also thought to play an important role in the process of caries

PDF(4) Cite This Paper. Abstract Streptococcus mutans is considered one of the primary causative agents of dental caries and can also be a source of infective endocarditis. The main virulence factors associated with cariogenicity include adhesion, acidogenicity, and acid tolerance. Each of these properties works coordinately to alter dental. Streptococcus mutans is one of the principal pathogens for the development of dental caries. Oral biofilms formed by S. mutans are constructed of insoluble glucan formation induced by the principal enzymes, GTF-I and GTF-SI, in sucrose-containing conditions.
