Painful hoof abscesses in horses develop when bacterial or fungal organisms enter the hoof structure through a wound or opening and cause infection in the inner tissues. The invading microorganisms and the ensuing immune response generate purulent exudate (pus) which causes pressure inside the hoof. This leads to pain, structural damage and lameness.
Founder is a common cause of lameness in horses. It involves damage to the laminar connection between the hoof wall and the coffin bone. This often leads to rotation and/or sinking of the coffin bone which causes severe pain and can permanently damage the hoof structure.
Podotrochlear Syndrome (also referred to as navicular syndrome or navicular disease) affects the podoÂtrochlear apparatus (PTA) of the equine foot and typically occurs in the forelimbs. The condition can cause a variable degree of lameness. There is no single cause of Podotrochlear Syndrome. Multiple structures including bones, tendons, and ligaments within the foot can be affected.
Potomac Horse Fever (PHF) is a bacterial disease that can result in severe colic, diarrhea, inflammation, depression and laminitis. In serious cases, it can be fatal to the horse. PHF is caused by infection with Neorickettsia risticii and typically affects horses grazing in pastures that border rivers or creeks. This bacteria may be found in bodies of water or in aquatic insects.
Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a progressive and painful dental condition that occurs in some horses. Primarily affecting senior horses, it typically involves the gradual degeneration of the incisors and canine teeth. Over time, the roots of these teeth are resorbed or dissolved.
