✦ Synopsis
Adhesion of yeasts and bacteria to silicone rubber is one of streptococcal and staphylococcal isolates. In addition, microthe first steps in the biodeterioration of silicone rubber voice bial adhesion in a stationary end point was generally lower prostheses. In this paper, adhesion of two streptococcal, to silicone rubber with an adsorbed salivary conditioning staphylococcal, Candida albicans and Candida tropicalis strains, film than without one. Nearly all microorganisms adhering isolated from explanted voice prostheses was investigated to an adsorbed salivary conditioning film, yeasts as well as to silicone rubber with and without a salivary conditioning bacteria, were stimulated to detach by the passage of an air film in a parallel-plate flow chamber. Within each microbial bubble through the chamber, but microorganisms adhering pair of one species, the strain with the most negative zeta directly to the silicone rubber, especially C tropicalis strains, potential adhered most slowly to negatively charged silicone detached in far lower numbers under the influence of a passrubber. No other clear relationships were obvious between ing air bubble. The present observations are in agreement adhesion to silicone rubber and microbial zeta potentials or with clinical in vivo findings that in patients with reduced cell-surface hydrophobicities, as by water contact angles. A saliva production after radiotherapy, the device life of the 1.5-h adsorbed salivary conditioning film appeared to pos-voice prosthesis is significantly shortened and suggests that sess components, presumably albumin and lysozyme, slow-isolated salivary components might be used as an antiing down the deposition of the yeasts and some of the adhesive.
