Hydrophobic interactions and the adherence of Streptococcus sanguis to hydroxylapatite.
Streptococcus sanguis demonstrated a high affinity for hydrocarbon solvents. When aqueous suspensions of the organism were mixed with either hexadecane or toluene, the cells tended to bind to the nonaqueous solvent. Increases in temperature resulted in a greater affinity of cells for hexadecane. Interaction between the cells and hexadecane was also enhanced by dilute aqueous sodium chloride and...
متن کاملAssociation of fimbriae with the hydrophobicity of Streptococcus sanguis FC-1 and adherence to salivary pellicles.
A nonhydrophobic mutant of Streptococcus sanguis FC-1 was isolated which has a greatly diminished capacity for attaching to experimental salivary pellicles on hydroxyapatite surfaces and for aggregating with salivary components. The mutant appears to be defective in the synthesis of fimbriae, as judged by electron microscopic observations and by its inability to exhibit twitching motility.
متن کاملCell surface components of Streptococcus sanguis: relationship to aggregation, adherence, and hydrophobicity.
Cell surfaces of aggregation, adherence, and hydrophilic variants of Streptococcus sanguis were compared with cell surfaces of the parent strain with regard to their protein and antigenic constituents. Cell surface molecules were released by digestion with mutanolysin. Extraction with sodium dodecyl sulfate (SDS) urea, lithium diiodosalicylate, and boiling water did not solubilize any material ...
متن کاملRecombination-deficient Streptococcus sanguis.
A UV-sensitive derivative was obtained from Streptococcus sanguis Challis. The organism could be transformed with a number of small streptococcal plasmids at frequencies equal to, or 1 logarithm below, the transformation frequencies for the parent organism. However, transformation with chromosomal DNA was greatly impaired in the UV-sensitive derivative.
متن کاملAcute septic arthritis due to Streptococcus sanguis.
OBJECTIVE To present a case of acute septic arthritis due to Streptococcussanguis, a member of the viridans group streptococci. CLINICAL PRESENTATION AND INTERVENTION A 73-year-old woman presented with fever and increasing swelling and pain of the right knee several weeks after she had been treated for severe periodontal disease. Arthrocentesis yielded purulent synovial fluid. S. sanguis was ...
