Serology of Streptococcus sanguis: localization of antigens with unlabeled antisera.
A new technique for the electron microscope localization of bacterial surface antigens, using unlabeled antisera, has been developed. This technique, called the "immuno-coating reaction" was applied to serological studies of Streptococcus sanguis, using antisera which had been shown to be specific for this species by gel diffusion analysis. The results of the immuno-coating reaction confirmed t...
متن کاملSaliva-mediated aggregation of Enterococcus faecalis transformed with a Streptococcus sanguis gene encoding the SSP-5 surface antigen.
The interaction of a high-molecular-weight salivary glycoprotein (agglutinin) with Streptococcus sanguis M5 leads to the formation of bacterial aggregates. We have previously shown that the SSP-5 surface antigen from S. sanguis M5 binds the salivary agglutinin and therefore may be involved in the aggregation process. Here we report the transformation of a nonaggregating Enterococcus faecalis st...
متن کاملHydrophobic 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 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 کاملStreptococcus Sanguis Biofilm Architecture and Its Influence on Titanium Corrosion in Enriched Artificial Saliva
Bacteria biofilm formation on metals is well-known, while biofilm architecture varies under different conditions. To date, few studies have determined the possible contribution to corrosion of titanium made by biofilm architecture. We investigated the interaction between the oral Streptococcus sanguis biofilm architecture and its influence on titanium corrosion in enriched artificial saliva usi...
