title: Effect of resistance possessed by certain enteric microorganisms upon orally inoculated Salmonella.
abstract: Mice shedding aerobic gram-negative microorganisms with high levels of resistance to tetracycline were orally inoculated with Salmonella typhimurium. Levels of resistance of salmonella isolated from tissue were shown not to be increased and, in most instances, were lower than preinoculation levels.
