Biology:Footrot
From HandWiki
Footrot in ruminants refers to various pathological conditions:
In sheep, contagious footrot is a universally distributed disease (affecting accessorily goats) characterised by chronic contagious epidermatitis of feet, especially in the fore limbs, caused by two anaerobic bacteria, not transferable to bovines.[1]
In cattle there has been a confusing terminology and several entities probably exist under such names as footrot (USA) Panaritium (Germany) or panaris (France).[2]
The following digital diseases of cattle[3] might have been called "footrot":
- Interdigital necrobacillosis: an acute severe phlegmon of interdigital connectif tissue, especially in the rear limbs.
- Interdigital dermatitis also called Scald: an acute or chronic inflammation of the interdigital skin of cattle, without extension to the subcutaneous tissue
- Interdigital skin hyperplasia: in cattle, excess of epidermal and hypodermal tissue occupying part of all of interdigital space, especially dorsally in the fore limbs.
- Pododermatitis circumscripta: in cattle, specific profiferative lesion of the sole-bulb junction, near the axial margin (rear limbs).
- Distal interphalangeal arthritis: purulent inflammation of the distal phalangeal joint, often a complication of one of the above cited conditions, especially in the rear limbs.
