Summary
# Equine Botulism: A Clinical Overview Botulism remains a significant threat to equine populations globally, caused by the neurotoxin produced by *Clostridium botulinum*, a widespread soil bacterium that disrupts neuromuscular transmission and causes rapidly progressive flaccid paralysis. Kali, Whitlock and Johnson's comprehensive review synthesises current evidence on the disease's pathophysiology, clinical manifestations, and diagnostic approaches—particularly relevant given that definitive diagnosis is frequently impractical in clinical settings, forcing practitioners to rely on clinical judgment and presenting signs. The authors emphasise that delays in case recognition precipitate rapid patient deterioration, and highlight the substantial practical obstacles inherent in managing recumbent horses, where intensive nursing care and the animal's size create significant welfare and logistical challenges. Key findings address the full disease spectrum from early presentation through to advanced recumbency, alongside available treatment modalities and evidence-based prevention strategies. For farriers, veterinarians and equine physiotherapists working with affected animals, this review provides crucial guidance on early identification and appropriate management protocols, whilst reinforcing the critical importance of prompt intervention to optimise outcomes in what remains a challenging and often fatal condition.

Practical Takeaways
- •Early recognition of botulism clinical signs is critical as delayed diagnosis leads to rapid deterioration; treatment decisions often must be made on clinical grounds alone
- •Recumbent botulism cases require intensive nursing support and specialized management due to the large body size of equine patients, making prevention and early intervention essential
- •Understand risk factors and prevention strategies for Clostridium botulinum exposure in your facility, as definitive diagnosis may not be achievable and prognosis worsens with treatment delays
Key Findings
- •Botulism is a severe and often fatal disease in equine patients worldwide caused by Clostridium botulinum neurotoxin
- •Definitive diagnosis is often impractical or impossible, requiring clinical experience and presenting signs for diagnosis
- •Delay in case identification and treatment results in rapid patient deterioration
- •Treatment of recumbent cases presents challenges due to patient size and requires intensive nursing care
