Poultry Bumblefoot (Pododermatitis) Study Guide
Overview and Clinical Importance
Bumblefoot (ulcerative pododermatitis) is a common bacterial infection and inflammatory condition affecting the plantar surface of the foot in poultry. It is characterized by swelling, abscess formation, and a characteristic dark scab on the footpad. The condition is primarily caused by Staphylococcus aureus, though Escherichia coli and Pseudomonas species may also be involved.
Bumblefoot is more common in heavier birds and males, and is frequently associated with poor husbandry practices. The condition can range from mild erythema to severe osteomyelitis and septic arthritis if left untreated. Understanding the pathophysiology, grading system, and treatment protocols is essential for NAVLE success.
