Blackleg in Sheep

Symptoms and diagnosis of blackleg in sheep 🩺

The symptoms of blackleg can vary depending on the site of infection. Here are some common signs to watch out for:

• Fever: Affected sheep often have a high fever.
• Lameness: Sudden onset of severe lameness, especially if one limb is involved.
• Swelling: Swelling and crepitus (a crackling sound) in the affected muscles.
• Rapid Decomposition: After death, the carcass bloats quickly and decomposes rapidly.

Diagnosis is typically based on clinical signs and necropsy findings. The presence of large numbers of Gram-positive rods at the margins of the lesion can confirm the diagnosis.

Unfortunately, treatment options for blackleg are limited and often ineffective once symptoms appear. Early intervention with high doses of antibiotics may help in some cases, but the success rate is low. Therefore, prevention is the best strategy.
