For the present study, we selected the monoclonal antibody S057, also well known as CR57, one component of the published mAb cocktail, because it provides broad neutralization of a variety of rabies virus strains via binding to glycoprotein G. The second model, botulism, is a rare but often fatal toxin‐mediated illness that occurs following ingestion of food‐borne bacterial spores or via pre‐formed toxin. Here, THBS1 is linked to botulism.
