Karies orsakas huvudsakligen av bakterien mutans streptococci, som leder till ett lågt pH-värde i munnen, vilket i sin tur påverkar emaljen. Dålig andedräkt. Dålig

It can thrive in temperature ranging from 18-40 degrees Celsius. The bacterium metabolizes different kinds of carbohydrates, creating an acidic environment in the mouth as a result of this process. This acidic environment in the mouth is what causes the tooth decay. S. mutans is one of the eight species belonging to the mutans group of Streptococci which are differentiated based on their heterogenicity in their genomic structure. It was first discovered and named by J Kilian Clarke in 1924 which were isolated and identified from carious lesions. Streptococcus mutans are gram-positive cocci shaped bacteria. These facultative anaerobes are commonly found in the human oral cavity, and is a major contributor of tooth decay.

Jensen B(1), Bratthall D. Author information: (1)Department of Cariology, School of Denistry, University of Lund, Malmö, Sweden. A new method for quantitating the numbers of mutans streptococci in saliva--the "Strip mutans" test- … 2019-06-01 Mutans streptococci counts in plaque and unstimulated Saliva at five weeks and best fit linear line. Linear reduction of mutans streptococci levels in plaque and unstimulated saliva to increasing frequency of xylitol chewing gum use at a constant daily dose (10.32 g/day). Species with maximum interference capacity against mutans streptococci included Lactobacillus paracasei, Lactobacillus plantarum, and Lactobacillus rhamnosus. Naturally occurring oral lactobacilli significantly inhibited the growth of both test strains of mutans streptococci and the subject's autologous mutans streptococci in vitro, and this effect was more pronounced in caries-free subjects.

The objective of this study was to evaluate the relationship between dental caries, the number of salivary colonies forming units of Mutans Streptococci (MS) and Lactobacillus (LB), and the nutritional status in a group of children from Transylvania. This observational study used a sample of 154 Mutans streptococci and caries in young children The main MS species, S. mutansand S. sobrinus, are facultative anaerobes, non-motile and catalase-negative gram-positive cocci.5,6 The central role of MS in the aetiology of ECC is now well established. The viridans streptococci are a large group of commensal streptococcal Gram-positive bacteria species that are α-hemolytic, producing a green coloration on blood agar plates (hence the name "viridans", from Latin "vĭrĭdis", green).

(serotypes d and g), and S. downei (serotype h) (11, Salivary mutans streptococci and lactobacilli were enumerated with chair-side kits at baseline and 1 day after the final ingestion. Results: A statistically significant reduction of the mutans streptococci levels was recorded after ingestion of the probiotic bacteria via the straw (p<0.05) and the tablets (p<0.01), which was in contrast to the placebo controls. Mutans streptococci are the most important bacteria associated with tooth decay.

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. S. mutans is one of the eight species belonging to the mutans group of Streptococci which are differentiated based on their heterogenicity in their genomic structure. It was first discovered and named by J Kilian Clarke in 1924 which were isolated and identified from carious lesions. The group of "mutans streptococci" was described as the most important bacteria related to the formation of dental caries. Streptococcus mutans, although naturally present among the human oral microbiota, is the microbial species most strongly associated with carious lesions.

Their genetic variability is however still not well understood.Genomes of 6 clinical S. mutans isolates of different origins, one isolate of S. sobrinus (DSM 20742) Salivary mutans streptococci and lactobacilli were enumerated with chair-side kits at baseline and 1 day after the final ingestion.

These are spherical bacteria, which usually accumulate in chain form. S. mutans occurs as a commensal in the oral cavity and is largely responsible for the development of caries. Strep Mutans a shortened term for Mutans Streptococci, is an acid-producing bacterium that attacks tooth enamel minerals which in turn causes tooth decay.
