What is thrush and where does it occur?

• A. Thrush is a bacterial infection of the hoof that affects the frog and surrounding tissue, commonly in damp conditions
• B. Thrush is a fungal infection of the skin around the hoof
• C. Thrush is a viral infection of the hoof
• D. Thrush is a parasitic infestation of the hoof wall

Answer: (A)

Thrush is a bacterial infection of the hoof that targets the frog and the surrounding tissue, typically developing when the frog sulci stay damp, dirty, and poorly cleaned. The bacteria thrive in that moist environment, and the tissue can become necrotic with a foul odor. This infection is defined by its location (the frog area) and its cause (bacteria, not fungi or viruses). It differs from fungal hoof problems, viral hoof conditions, or parasitic infestations, which involve different organisms and usually present with different signs. Prevention centers on keeping the hoof clean and dry, removing muck from the frog area, and ensuring regular hoof care to promote good drainage and healing.
