Digital dermatitis is a disease that causes lameness in cattle. It was first discovered in Italy in 1974 by Cheli and Mortellaro. This disease is caused by a mixture of different bacteria. Anaerobic bacteria, including spirochetes of the genus Treponema, are found in the lesions associated with the infection.
Initially, signs of bone spavin may include sporadic and vague hindlimb lameness. Some horses may become uncomfortable in one lead, or may demonstrate stiffness walking downhill. In many cases lameness worsens, becoming more obvious and consistent. Advanced cases may have a bony swelling on the hock, typically on the inside of the joint.
Burning the upper layer of soil to eradicate left-over spores is the best way to stop the spread of blackleg from diseased cattle. Diseased cattle should be isolated. Treatment is generally unrewarding due to the rapid progression of the disease, but penicillin is the drug of choice for treatment. Treatment is only effective in the early stages ...
The acute phase is the first 72 hours following the initiation of clinical signs. Treatment response during this time determines if the horse will go into the subacute phase or chronic phase. Clinical signs at this time include bounding digital pulses, lameness, heat, and possibly response to hoof testing. [1] Subacute phase
Nasal signs may be prominent, with nasal discharge and stertorous respiration. Some animals also develop foot lesions, beginning with coronitis, with consequent lameness. In sheep, this can lead to knee-walking. In cattle, constant changing of position of the feet gives bluetongue the nickname the dancing disease. [12]
There is then progression to the heels which become raw and cattle will experience pain. Chronic cases will show changes of the hoof including hyperplasia of the interdigital tissues and muscle atrophy in the affected limb. The horn may become underrun. [1] Diagnosis is principally based on history and clinical signs.
The characteristics of the disease are the sudden onset of fever, stiffness, lameness and nasal and ocular discharges. BEF often causes hypocalcaemia which in turn generates clinical signs such as depression, cessation of rumination, muscle tremors and constipation. [citation needed]
F. necrophorum is also a cause for lameness in sheep. Its infection is commonly called scald or foot rot. It can last for several years on land used by either sheep or cattle, and is found on most land of this type throughout the world. Due to its survival length in these areas, it is unrealistic to try to remove it.
