[Mild course of botulinus intoxication (author's transl)].

Botulinus poisoning generally ends fatally after an only short course, mild forms being rare. In four members of a family who had eaten deep-frozen grilled sausages symptoms of botulinus poisoning developed, predominantly marked by disturbances of the autonomic nervous system. The course was so mild that hospitalization was not necessary nor was specific antitoxin administration. All clinical symptoms had disappeared after nine weeks. But special clinical and neurophysiological studies (electromyography, pupillography, electroencephalography) demonstrated abnormalities for very much longer. Botulinus poisoning was proven in animal tests and neutralization tests with botulinus antitoxin. The epidemiology, source of infection, and clinical symptoms suggest botulinus type B poisoning.
