title: In vitro attachment of Salmonella typhimurium to chick ceca exposed to selected carbohydrates.
abstract: This investigation was designed to study the effect of selected carbohydrates on the in vitro attachment of Salmonella typhimurium to the ceca of chickens 1 and 2 weeks of age. Ceca were surgically removed from chickens immediately after euthanasia, inverted on glass rods, and then rinsed with sterile saline before being exposed to S. typhimurium in a solution of saline containing the carbohydrate to be evaluated. Attachment of S. typhimurium to ceca was reduced in 1-week-old chicks in the presence of N-acetyl-D-galactosamine, L-fucose, D-galactose, L+arabinose, and D+mannose. Minimal or no reduction in attachment of S. typhimurium was noted when ceca from 2-week-old chicks were exposed to the same compounds. Carbohydrates investigated and found to be ineffective for reduction of S. typhimurium attachment to chick ceca were D+fucose and N-acetyl-D-glucosamine.
