Lactobacillus characterization and effects on oral biofilm

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 ). Streptococcus mutans. 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. Based on differences in the glycopolymer structures S. mutans is Over the past 25 years collection and analysis of clinical, dietary and microbiological data have led to the conclusion that caries is a bacterial infection, initiated by mutans streptococci which can be transmitted within a family by saliva. Bacteria attach themselves selectively to various oral surfaces.

A systematic review.

However, it remains unknown whether severe dental caries that extend to pulp space represent a possible route of infection. In the present study, we evaluated the virulence of S. mutans for IE development using Quantitative analysis of the total aerobic flora and mutans streptococci in saliva was performed.

Mutans streptococci colony counts per ml of saliva were performed on Mitis-Salivarius Bacitracin agar collected on the first day and 14 days post-intervention. Results: A statistically significant reduction (p<0.001) in salivary mutans streptococci counts was recorded in both groups B and C after 14 days of probiotic ingestion. 2009-07-31 A new method for the estimation of mutans streptococci in human saliva.

(serotype b), S. mutans (serotypes c, e, and f), S. sobrinus. (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.

Habitat: Strep mutans can stick to tooth surfaces and live in tiny cracks in teeth. It lives and 20 Jan 2016 Before the science of tooth decay was well understood, there were all kinds of theories about things that harm the teeth. For instance, some Streptococcus mutans, generally known as a major pathogen of dental caries, is also a possible causative agent of bacteremia and infective endocarditis. [.

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. Strep Mutans a shortened term for Mutans Streptococci, is an acid-producing bacterium that attacks tooth enamel minerals which in turn causes tooth decay. Of the hundreds of different types of bacteria living in your mouth, only a handful are thought to cause gum disease, but only Strep Mutans is implicated as the main cause of dental decay.

Also, the level of salivary anti-S. mutans IgA was determined by ELISA. Children with rampant caries showed the highest OHI-S value. The highest total counts of microorganisms were found in the group of children with caries. Streptococcus mutans gehören zu den grampositiven Kugelbakterien, welche sich physiologisch bei fast allen Menschen in der Mundflora befinden. Diese wachsen unter fakultativ anaeroben Bedingungen, das heißt sie können sich unter Anwesenheit von Sauerstoff vermehren, aber auch unter Abwesenheit.
