The current status of botanical screening efforts, as well as in vivo studies of their effectiveness and toxicity, are summarized and the structure and antimicrobial properties of phytochemicals are addressed.
Antimicrobial efficacy of a silver-zeolite matrix coating on stainless steel
A silver- and zinc-containing zeolite matrix (AgION) used as a coating for stainless steel was tested for antimicrobial efficacy against Escherichia coli 25922, Staphylococcus aureus 25923,
On the relative importance of specific and non-specific approaches to oral microbial adhesion.
It is argued that the same basic, physicochemical forces are responsible for so-called 'non-specific' and 'specific' binding and that from a physico-chemical point of view the distinction between the two is an artificial one.
Glucan-binding factor in saliva
It is suggested that whole saliva contains a component, tentatively identified as lipoteichoic acid, which can complex with glucans in a relatively hydrophobic solvent, which may be important in the adhesion of oral streptococci to saliva-coated surfaces.
Physicochemical and structural studies onAcinetobacter calcoaceticus RAG-1 and MR-481—Two standard strains in hydrophobicity tests
Contact angles with polar liquids, water and formamide, were considerably higher on RAG-1 than on MR-481, in accordance with their relative hydrophobicities as measured by MATH, but no significant differences in contact angles were observed between the two strains with apolar liquids like diiodomethane,α-bromonaphthalene, and hexadecane.
Response of microbial adhesives and biofilm matrix polymers to chemical treatments as determined by interference reflection microscopy and light section microscopy
Results indicate that both polymers bear acidic groups and thus act electrostatically with cations and are able to enter into hydrophobic interactions.
Energetics of the initial phase of adhesion of Streptococcus sanguis to hydroxylapatite
The strongly positive entropy values and the lesser temperature dependence of the saliva-coated hydroxylapatite system suggest that another entropy-driven process is imposed on the electrostatic linkages, which supports a role for hydrophobicity, suggesting that a combination of electrostatic and hydrophobic forces mediate the initial adhesion of S. sanguis to the salivary pellicle.
