Fusobacterium necrophorum is a gram-negative obligate anaerobic bacillus that has been associated with this type of infection. Thrush usually presents as foul smelling black matter in the sulci of the frog.
Thrush commonly occurs as a result of poor environmental con- ditions but may occur in horses that are well kept. If the hoof has abnormalities such as excessive length, contracted heels, or shod with a full pad thrush may be more likely to develop.
Horses may have thrush but not show lameness until the sensi- tive structures are involved. To eliminate thrush it is important is more likely to develop an abscess or “white line disease” to provide a clean environment and give the hoof a balanced because the bacteria and fungi are able to invade the abnormal trim to remove the necrotic tissue.
