What is the tx for lumpy jaw?

• A. Antibiotics for 6 weeks
• B. Surgical removal of nodules
• C. Vaccination to prevent progression
• D. No treatment, cull affected animals

Answer: (D)

Lumpy jaw is a chronic mandibular osteomyelitis caused by Actinomyces bovis, and its bone involvement makes it very hard to eradicate. The infection forms hard granulomas and sequestra in the jaw, and antibiotics have limited penetration into bone and often fail to provide a durable cure. Surgery to remove nodules is not reliably curative and can be impractical or risky, especially with extensive or bilateral disease. There is no effective vaccine to prevent progression, so the best chance of reducing economic losses in a herd is to remove affected animals rather than pursue prolonged, costly therapy that is unlikely to succeed.
