MECHANISM OF ACTION OF BACTERIAL TOXINS MECHANISM

The bacterial enterotoxins , cholera toxin (CT) and the closely related E.coli heat-labile toxin (LT) have been found to be the most potent mucosal immunoenhancers (adjuvants) we know of today. Hence, much research is focused on understanding the mechanism behind their potent augmenting function following mucosal immunizations and oral immunizations, in particular. These holotoxins consist of

Why Bacillus thuringiensis insecticidal toxins are so

The suggestion that bacterial toxins might have a role in the causation of SIDS had been made previously [3, 4], but the novel features of the common bacterial toxin hypothesis were the suggestion that the putative toxins were very common, i.e. virtually all infants encounter them in the first year of life, and the site of origin of the toxins was the upper respiratory tract rather than the
