pH Regulation by Streptococcus mutans

Journal of Dental Research, 1992
The intracellular pH (pH i ) optimum for glycolysis in Streptococcus mutans Ingbritt was determined to be 7.0 by use of the ionophore gramicidin for manipulation of pH i . Glycolytic activity decreased to zero as the pH i

Immunoperoxidase staining of Streptococcus mutans

Archives of Oral Biology, 1974
Abstract Cells from two scrologically different strains of Streptococcus mutans strain B13 and strain IB were treated immuno-histochemically for electron microscopy. Both strains were incubated first with specific rabbit anti-B13 serum and then with sheep anti-rabbit serum labelled with horse-radish peroxidase and finally histochemically stained for ...

Streptococcus mutans Endocarditis

Annals of Internal Medicine, 1974
Abstract Nine patients withStreptococcus mutansendocarditis were seen between 1966 and 1973. They had the typical clinical picture of subacute bacterial endocarditis, with fever, heart murmur, and ...

Empyema due to Streptococcus mutans

Chest, 1977
Empyema due to Streptococcus mutans occurred following dental manipulation in two patients with periodontal disease. Isolation of this dental pathogen from pleural fluid localized the site of origin of the empyemas to the oropharynx and precluded the need to search for a remote intra-abdominal source of these pleuropulmonary infections.

Recurrent streptococcus mutans endocarditis

The American Journal of Medicine, 1987
Recurrent bacterial endocarditis is associated with several risk factors including parenteral drug abuse, past valvular heart disease, and periodontitis. Recurrence rates vary from 2 to 18 percent for a single recurrence, and 1 to 5 percent for two recurrences.

Growth of Streptococcus mutans in a chemostat

Archives of Oral Biology, 1974
Abstract A strain of Streptococcus mutans isolated from a carious lesion of a patient and known to cause caries in hamsters and monkeys were grown in a complex medium in a chemostat. There were changes in the ability of the organism to stick to surfaces, glucose utilization, and acid production of the organism when grown at different dilution rates.

Streptococcus mutans Dextransucrase: A Review

1978
Publisher Summary Two factors contribute to the cariogenic potential of Streptococcus mutans ( S. mutuns). These factors include its ability to produce high yields of lactic acid from a variety of carbon sources and its ability to adhere to hard surfaces by the action of its extracellular polysaccharides. S.

Cariogenicity of Mutants of Streptococcus mutans

Journal of Dental Research, 1980
In this study, we induced a number of mutants of S. mutans differing in their abilities to synthesize glucan and produce acid. When tested for cariogenicity in gnotobiotic rats, "high pH" mutants caused less caries, but could not supplant a cariogenic parent strain.

Pulp response to Streptococcus mutans

Oral Surgery, Oral Medicine, Oral Pathology, 1987
The maxillary molar pulps of germ-free rats were mechanically exposed, and suspensions of a strain of freshly grown Streptococcus mutans were applied to the pulp wounds. The pulps were left open to the oral environment, and the animals were maintained in the isolator until they were killed in groups after 2, 7, and 28 days.

Streptococcus mutans, not detected?

Oral Microbiology and Immunology, 1989
The growth of Streptococcus mutans was followed for three years in 24 healthy 12‐17 year‐old children, who were selected for the study on the basis of undetectable levels of salivary S. mutans. The saliva samples were cultured by a dip‐slide method based on mitis‐salivarius agar supplemented with sucrose and bacitracin.
