pH regulation by Streptococcus mutans.
The intracellular pH (pHi) optimum for glycolysis in Streptococcus mutans Ingbritt was determined to be 7.0 by use of the ionophore gramicidin for manipulation of pHi. Glycolytic activity decreased to zero as the pHi was lowered from 7.0 to 5.0. In contrast, glycolysis had an extracellular pH (pHo) optimum of 6.0 with a much broader profile. The relative insensitivity of glycolysis to the lower...
متن کاملStreptococcus oligofermentans Inhibits Streptococcus mutans in Biofilms at Both Neutral pH and Cariogenic Conditions
Homeostasis of oral microbiota can be maintained through microbial interactions. Previous studies showed that Streptococcus oligofermentans, a non-mutans streptococci frequently isolated from caries-free subjects, inhibited the cariogenic Streptococcus mutans by the production of hydrogen peroxide (HP). Since pH is a critical factor in caries formation, we aimed to study the influence of pH on ...
متن کاملGenetic transformation of putative cariogenic properties in Streptococcus mutans.
Rough colonial morphology and bacteriocin production, two properties which may be associated with the cariogenicity of Streptococcus mutans, were transformed into several strain GS-5 mutants defective in each respective property. Transformation was determined by observing the frequency of cotransfer of these properties with different reference markers. The rough colonial transformants were iden...
متن کاملGenome sequence of Streptococcus mutans UA159, a cariogenic dental pathogen.
Streptococcus mutans is the leading cause of dental caries (tooth decay) worldwide and is considered to be the most cariogenic of all of the oral streptococci. The genome of S. mutans UA159, a serotype c strain, has been completely sequenced and is composed of 2,030,936 base pairs. It contains 1,963 ORFs, 63% of which have been assigned putative functions. The genome analysis provides further i...
متن کاملDoes Cariogenic Streptococcus mutans Play a Role in Cardiovascular Disease?
The link that exists between oral health and the entire well-being of the body is continuously becoming more emphasized. As illnesses such as cardiovascular disease become more prevalent, dentists and researchers have suggested that a link between the transfer of bacteria in the mouth into the blood stream plays a direct cause in onset of the disease in some patients. The American Dental Associ...
