J Dent Res 71: 1785 –1791; erratum in J Dent Res 72:87–88, 1993. Google Scholar | SAGE Journals | ISI Previous cross-sectional studies using bacteriocin profiles, serotyping, or genotyping suggest that mothers are the principle source of mutans streptococci (MS) to their infants. This study determined the commonality of MS genotypes between mothers and their infants at the time of initial acquisition. A short introduction to the Nanobug, Streptococcus mutans, a popular bacterium that can stick to the tooth surface and in tiny cracks in teeth.

Mutans streptococci are considered to be causative agents of dental caries and have been classified into 5 species: Streptococcus cricetus (serotype a), S. rattus (serotype b), S. mutans (serotypes c, e, and f), S. sobrinus (serotypes d and g 1984-09-01 Dental caries is an infectious and transmissible disease. The mutans streptococci (MS) are infectious agents most strongly associated with dental caries. Earlier studies demonstrated that infants acquire MS from their mothers and only after the eruption of primary teeth. The heritability of mutans streptococci colonisation in 48 pairs MZ and in 26 pairs of DZ twins was estimated to be 52%.

Acid adaptation in Streptococcus mutans UA159 alleviates sensitization to environmental stress due to RecA deficiency. Background: This is an initial study of the biofilm of Streptococcus mutans (S. mutans) and Aggregatibacter actinomycetemcomitans (A.a). S. mutans and A.a are bacteria that cause infection diseases in the oral cavity.

Morphologically, mutans streptococci grown as distinctive microcolonies only in the presence of sucrose-supplemented medium. Figure 6 Microbiological parameters of S. mutans cultures in medium A without sucrose (open symbols) and medium B with 5% sucrose (filled symbols): / log BC, / log CFU, ∆/ vitality (VS) at 24 h, 48 h, and 144 h incubation time. Streptococcus mutans is specifically suppressed by intensive treatment with chlorhexidine gel, but the time for recolonization and the effect on other oral bacteria

Caries Res 1989; 23: 378-384. 7. Milgrom P, et al. Mutans streptococci dose response Penicillin G potassium salt is used to study murosomes of staphylococci and the penicillin-induced lysis of Streptococcus mutans. Mode of Action: Penicillin G region of mutans streptococcal glucosyltransferase protects against dental caries. from two regions of glucosyltransferase (GTF) of mutans streptococci.
Symptoms may include pain and difficulty with eating. Complications may include inflammation of the tissue around the tooth, tooth loss and infection or abscess formation. Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay. It is part of the " streptococci " (plural, non-italic lowercase), an informal general name for all species in the genus Streptococcus. Streptococcus mutans is a gram-positive facultative anaerobic bacterium that belongs to a group of mutans streptococci consisting of S. sobrinus and several other species (Figure 4). The colony morphology of S. mutans is rough when grown on plates with mitis salivarius agar, a selective medium for mutans streptococci, whereas that of S. sobrinus is smooth ( Figure 5 ).

mutans and Strep. sobrinus in dental plaque, a nested PCR ampliﬁcation based on the 16S rRNA gene was employed. Streptococci have been divided into six groups on the basis of their 16S rDNA sequences: S. anginosus, S. gallolyticus, S. mitis, S. mutans, S. pyogenes and S. salivarius. The 16S groups have been confirmed by whole genome sequencing (see figure).
Streptococcus mutans is a major etiological agent of human dental caries. Similar to other streptococci, the cell wall of S. mutans is composed of multiple layers of peptidoglycan decorated with glycopolymers that are characterized by the presence of l-rhamnose.

Streptococci have been divided into six groups on the basis of their 16S rDNA sequences: S. anginosus, S. gallolyticus, S. mitis, S. mutans, S. pyogenes and S. salivarius. The 16S groups have been confirmed by whole genome sequencing (see figure). 2021-04-07 · The mutans streptococci were once the primary focus of research dedicated to understanding the etiology of dental caries. That focus has now shifted to an emphasis on the ecological balances and complexities within the entirety of the plaque microbiome. Within that framework there are considerable 2010-07-02 · Mutans streptococci, candida strains and cultivation. Five strains of mutans streptococci (MS) including both laboratory reference strains (S.
The non-shared environment contribution was estimated to be 48%. Conclusions: These results suggest that variation in the salivary levels of the mutans streptococci is significantly contributed by genetic factors. S. mutans group Viridans streptococci-Wikipedia As the cementum of root surfaces is more easily demineralized than enamel surfaces, a wider variety of bacteria can cause root caries, including Lactobacillus acidophilus , Actinomyces spp., Nocardia spp. , and Streptococcus mutans . Mutans streptococci are a group of bacteria significantly contributing to tooth decay.
