context: At the end of the 19th century, 34 musicians preparing to play at a funeral in Belgium ate raw home-made ham. During the day, most musicians began to show symptoms of botulism. As a result, 3 people died, and another 10 were in hospital for a week in serious condition. The bacteriologist Emil van Ermengem isolated the causative agent from the remains of the ham and the spleen of the victims and named it Bacillus botulinus. He also found that the toxin is not formed in the patient’s body, but in the thickness of the ham. At the same time, the first immune serum was created to treat botulism. Researcher Alan Scott in 1973 conducted the first animal tests of botulinum toxin to reduce the activity of hyperkinetic muscles, and then, in 1978, under his leadership, human pathogen tests began, according to the approved FDA protocol [12].
