Abstract

Binding of the purified type C 7S (neurotoxin), 12S and 16S botulinum toxins to epithelial cells of ligated small intestine or colon of the guinea pig ( test) and to pre-fixed gastrointestinal tissue sections ( test) was analysed. The 16S toxin bound intensely to the microvilli of epithelial cells of the small intestine in both and tests, but did not bind to cells of the stomach or colon. The neurotoxin and 12S toxin did not bind to epithelial cells of the small intestine or to cells of the stomach or colon. Absorption of the toxins was assessed by determining the toxin titre in the sera of guinea pigs 6-8 h after the intra-intestinal administration of the toxins. When the 16S toxin [1 x 10 minimum lethal dose (MLD)] was injected, 200-660 MLD ml was detected in the sera, whereas when the 12S toxin (2 x 10 MLD) or 7S toxin (2 x 10 MLD) was injected, little toxin activity was detected in the sera. Therefore, the haemagglutinin of type C 16S toxin is apparently very important in the binding and absorption of botulinum toxin in the small intestine.
