[Inhibition of adhesion to buccal epithelial cells of Pseudomonas aeruginosa by dextran].
Adhesion of Pseudomonas aeruginosa strains to buccal epithelial cells appears to be a necessary precondition for colonization and infection of respiratory tract. There are many strategies to prevent host organisms for Pseudomonas aeruginosa. The purpose of these studies was to evaluate the potential for preventing adhesion of Pseudomonas aeruginosa to epithelial cells with dextran. Dextran (5,000 MW) inhibited adhesion of Pseudomonas aeruginosa to buccal cells, at 20 mM was most inhibitory. The inhibitory effect appeared to be nonspecific because other neutral polysaccharides (glycogen and mannan) were also inhibitory. Dextran is an inexpansive and nontoxic agent and may be useful to prevent colonization and infection of respiratory tract with Pseudomonas aeruginosa.
