Mechanisms of oral staphylococcal enterotoxin B-induced emesis in the monkey (38553)

Vomition is the most consistent response to oral SEB challenge in the monkey. The technique of cross-circulation clearly differentiates local neural phenomenon from humoral mechanisms. Our results support the theory that SED-induced vomition follows stimulation of local neural receptors in the gut. The evidence indicates no significant amount of enterotoxin absorption or stimulation of vomition by any centrally acting humoral mechanism.
