Natural Immunoreactivity of Secretory IgA to Indigenous Strains of Streptococcus mutans From Chinese Spousal Pairs

BACKGROUND Dental caries is a well-known biofilm-mediated disease initiated by Streptococcus mutans, which should infect and colonize in a milieu perfused with components of the mucosal immune system. Little is known, however, regarding the relationship between the natural secretory IgA activity and S. mutans of a variety of diverse genotypes. OBJECTIVES The current study aimed to use spousal...

Antagonistic action of indigenous Streptococcus mutans strains.

Dental caries is an infectious process which ultimately destroys the tooth. Streptococcus mutans is considered to be the main agent causing this disease. If microorganisms with antagonistic action on S. mutans were found, they might provide a way of avoiding or controlling the disease. Within the framework of the Oral Microbial Ecology approach, the aim of this project was to identify S. mutans...

The Comparison of Proteins Elaborated by Streptococcus mutans Strains Isolated from Caries Free and Susceptible Subjects

Association of Dental Caries, Streptococcus Mutans Counts and Secretory IgA with Tobacco Smoking

This article reviewed smoking oral diseases Cigarette smoke affects the oral cavity first, so it is evident that smoking has many negative influences on oral cavity, for example, dental caries The article also discusses the relationship between smoking, Streptococcus mutans counts, secretory IgA (S-IgA) and dental caries in detail. Dental caries were significantly related to the presence of Str...

Buoyant densities of DNA from various strains of Streptococcus mutans.

CARIOGENESIS has been correlated with the presence of certain streptococci in the oral cavity and on tooth surfaces. Various studies dealing with the serological relationships of cariogenic strains resembling Streptococcus mutans (CLARKE, 1924; EDWARDSSON, 1968) have implied a certain amount of heterogeneity within this group (Tow and SHKLAIR, 1967; ZINNER and JABLON, 1968; BRATTHALL, 1970). Re...

Population structure of plasmid-containing strains of Streptococcus mutans, a member of the human indigenous biota.

There are suggestions that the phylogeny of Streptococcus mutans, a member of the human indigenous biota that is transmitted mostly mother to child, might parallel the evolutionary history of its human host. The relatedness and phylogeny of plasmid-containing strains of S. mutans were examined based on chromosomal DNA fingerprints (CDF), a hypervariable region (HVR) of a 5.6-kb plasmid, the rRN...
