THRUSH is an unpleasant infection of the central and collateral grooves of the horse's frog. Keratinolytic (keratindissolving) bacteria, including the sheep foot rot organism Fusobacterium necrophorum, attack softened tissues of the frog, causing it to rot away.
The most obvious sign of thrush is a foul-smelling, black discharge from the frog, which itself may have softer spots and appear irregular in shape.. Despite the offensive smell and discharge, many horses with thrush show no obvious discomfort or lameness.
If the infection is severe it can spread to involve the deeper structures in the hoof, such as the digital cushion, hoof wall and heel bulb, resulting in disintegrating horn. Then there may be some pain around the frog and bulbs of the heel, and filling of the limbs and lameness of varying degrees when sensitive tissues are involved.
