Intoxication by tremorgenic mycotoxin (penitrem A) in a dog.

A 1-year-old Siberian Husky dog presented with severe muscle tremors after ingestion of a mouldy hamburger bun. Penicillium crustosum and the tremorgenic mycotoxin penitrem A were isolated from the remaining portion of the hamburger bun. When grown in pure culture, the isolate of P. crustosum produced large amounts of penitrem A, along with other penitrem compounds. This is the first reported Australian case of toxicosis by naturally occurring penitrem A.
