摘要

Botulism is a poisoning caused by a potent neurotoxin produced by Clostridium botulinum, an anaerobic bacteria. The botulism toxin is so strong that one gallon of it could kill half the people in the United States. Clostridium botulinum can be foundin a variety of places. It can inhabit soils, bottom sediments of fresh and salt waters, the intestinal tracts of mammals, birds, and fish, and the gills and viscera of shellfish (US FDA 2001). At the present time, there are eight known botulism toxins(types A, B, Cl, C2, D, E, F, and G), but by far type Cl causes the most severe problems in mink. Mink of all ages are susceptible to botulism type C (Loftsgard et al., 1970). Mink are also susceptible to types A and B, but to a much lesser extent (Quortrup and Gorham, 1949). The spores of botulism type C are very heat resistant; in fact, they can be boiled for 60 minutes and still be viable. The spores themselves are harmless, but under the right conditions, spores can hatch and produce the deadly toxi
