Surgically altered and normal chickens were inoculated orally with Salmonella typhimurium and, in some instances, ferric oxide, and intestinal infection was monitored by sampling feces and cecal contents. Salmonellae initially appeared in feces in 1.5 to 22 hours, and ferric oxide in 3 to 5 hours. The organisms could not be isolated from the ceca until 24 hours. Birds whose ceca had been ligated or surgically removed had a higher shed rate than the controls. No evidence indicated that the cecum plays an essential role in establishing or maintaining intestinal infection with S. typhimurium.
