[Enterotoxic properties of salmonellae and their neurotoxins]

Most of live S. typhimurium cultures are capable of intraintestinal proliferation and possess enterotoxic activity. The capacity of S. typhimurium strains for producing enterotoxins is not connected with their origin. The parenteral immunization of rabbits with corpuscular vaccines prepared from S. typhimurium induced changes in the sensitivity of different sections of the small intestine of the animals to the enterotoxic action of live homologous cultures. Neurotoxin isolated from S. typhi was found to possess enterotoxic activity.
