botul-, botuli- +
(Latin: [botulus] sausage)
It is characterized by vomiting, abdominal pain, difficulty of vision, nervous symptoms of central origin, disturbances of secretion, motor disturbances, dryness of the mouth and pharynx, dyspepsia, a barking cough, mydriasis, and ptosis.
In adults, botulism is typically caused by the ingestion of preformed toxin; in some cases, however, it results from the production of toxin in the gastrointestinal tract by ingested organisms.
Botulism is the broader term; allantiasis refers only to sausage poisoning.
