Lymphangitis Equine Disease

Equine disease Lymphangitis is also known as equine Fat/Big Leg Disease or Weed or Monday Morning Disease.

Equine Lymphangitis is caused by a bacterial invasion commonly Corynebacterium pseudotuberculosis. It causes severe inflammation and swelling and is generally found in a horse’s limb.

Another form of equine lymphangitis is Ulcerative Lymphangitis. Hard nodules and abscesses form which discharge a badly odourous, greenish discharge. This form of lymphangitis can be characterised by many small, open sores.

SYMPTOMS OF LYMPHANGITIS EQUINE DISEASE
Equine Lameness is the primary symptom in the horse. It can be to varying degrees.
In the early stages of Equine lymphangitis there is an oedema on the surface of the skin. When pressed the depression stays. This is known as a ‘pitting odema’.
If it has progressed further the symptoms are:
• The horse may be have a fever (pyrexic)
• Extreme swelling of a limb
• Usually the swelling occurs in the hindlimb and can extend to the hock and stifle.
• The swelling can also continue through the udder or sheath and along the subcutaneous abdominal veins.
• Swelling can reach twice or even three times from its normal size
• Senstive to touch.
• Chronically the swelling will be firm – this is due to the occurrence of fibrosis and scarring.
• The wound may occasionally secrete serum

CAUSES OF LYMPHANGITIS EQUINE DISEASE
Equine Lymphangitis is caused by a bacterial infection usually associated with an open wound or an abrasion. The wound itself may be minor but opportunistic bacteria will use this as an entry point to access the lymph ducts.

TREATMENT OF LYMPHANGITIS EQUINE DISEASE
Antibiotics, analgesics and anti-inflammatories control the underlying infection, pain and swelling of Equine Lymphangitis. Surgery may be required in most severe cases to drain any abscesses.
