Botulism
June 2015
Dr Sarah-Jane Wilson Regional Manager Northern Australia
Botulism • Clostridial bacteria • Can form spores which are
environmentally stable in many conditions
• Produces a neurotoxin (affects nerves)
• Cattle, sheep, horses, pigs, horses, goats, poultry and humans can all be affected
• Preventable, but difficult (and very unproductive) to treat • Predisposition to bone/carrion chewing can increase risk of
disease occurrence in unvaccinated livestock (Northern Aus).
Clinical signs • Sudden death • Ascending flaccid paralysis • Drooling • Trouble swallowing • Often lie with head turned to
flank
Vaccination protocols for botulism
Sheep and cattle: Traditional protocol: • 2 doses (4-6 weeks apart) • Yearly booster
Cattle only alternative options: • Single initial dose • 1-3 yearly
booster depending on product
Other preventative measures Keep aggregation areas and watering points free from bones and carcases
Protein and phosphorus supplementations may help reduce predisposition to bone chewing
Provide good quality silage/hay free from contaminants (Fodder vendor declarations)
