What disease is caused by Streptococcus mutans?
Streptococcus mutans, a pathogen of dental caries, is known to be associated with bacteremia and infective endocarditis (IE).
What do Streptococcus mutans do?
Streptococcus mutans, which causes dental caries, splits the sucrose in food and uses one of the sugars to build its capsule, which sticks tightly to the tooth. The bacteria that are trapped in the capsule use the other sugar to fuel their metabolism and produce…
Why is Streptococcus mutans harmful?
mutans. Oral streptococci have both harmless and harmful bacteria. However, under special conditions commensal streptococci can become opportunistic pathogens, initiating disease and damaging the host. Imbalances in the microbial biota can initiate oral diseases.
What is Streptococcus mutans famous for?
Mutans streptococci are believed to be the major pathogens of dental caries, because they are frequently isolated from cavitated carious lesions, possess properties to induce caries formation in animals fed a sucrose-rich diet, show highly acidogenic and aciduric properties, and possess cell surface proteins associated …
What is the difference between mutans streptococci and Streptococcus mutans?
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.
What bacteria causes dental caries?
Streptococcus mutans is the main cause of dental decay. Various lactobacilli are associated with progression of the lesion.
What kills Streptococcus mutans?
First, A12 makes hydrogen peroxide, a chemical weapon that kills S. mutans. Yes, hydrogen peroxide- the same stuff we use to disinfect wounds! Hydrogen peroxide is highly reactive and can kill most germs.
How is S. mutans treated?
Conclusions. An orthodontic patient with high levels of S mutans received professional treatment with 1% chlorhexidine collagen gel. Microbiologic tests showed that the number of microorganisms was reduced, and a reversal of the caries risk was observed.
What means cariogenic?
Medical Definition of cariogenic : producing or promoting the development of tooth decay cariogenic foods cariogenic bacteria.
How does S. mutans adhere to teeth?
mutans adhere to the primary colonizers by cell-to-cell interactions. Subsequent bacterial growth on tooth surface leads to formation of biofilm on the teeth, also called dental plaque [5,7].
How does S. mutans spread?
These bacteria can pass from person to person through the transfer of saliva. The passing of MS bacteria from mother to child is called vertical transmission. Tooth decay is a bacterial infection that can spread through saliva from the mother to the child just as a cold or flu virus would spread.
What type of bacteria is the cause of dental caries Chapter 13?
There are two specific groups of bacteria found in the mouth that are responsible for dental caries: Mutans streptococci (Streptococcus mutans) Lactobacilli.
What kind of bacteria is Streptococcus mutans found in?
Stain of S. mutans in thioglycollate broth culture. 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.
How does Streptococcus mutans contribute to tooth decay?
Along with S. sobrinus, S. mutans plays a major role in tooth decay, metabolizing sucrose to lactic acid. The acidic environment created in the mouth by this process is what causes the highly mineralized tooth enamel to be vulnerable to decay.
How does Streptococcus mutans cause endocarditis?
About 20% of the endocarditis cases attributed to viridans streptococci are caused due to S. mutans. The organism moves through the blood and can bind to a pre-existing injury to the endothelium that might expose extracellular matrix components such as fibronectin, laminin, and collagen.
Are there any natural remedies for Streptococcus mutans?
Various other natural remedies have been suggested or studied to a degree, including deglycyrrhizinated licorice root extract, tea tree oil, macelignan (found in nutmeg), curcuminoids (the main components of turmeric), and eugenol (found in bay leaves, cinnamon leaves and cloves).
