Mud Fever

Mud fever (also known as dew poisoning or pastern dermatitis) is a group of diseases of horses causing irritation and dermatitis in the lower limbs of horses. Often caused by a mixture of bacteria, typically Dermatophilus congolensis, and Staphylococcus spp, mud fever can also be caused by fungal organisms (dermatophytes). Photosensitization, chorioptic mange mites, contact dermatitis and other conditions also contribute to some cases. This condition is often called scratches or dew poisoning, but is also known as pastern dermatitis, grease heel, or greasy heel.

Mud fever affects most horses and ponies during winter and early spring. Resulting in painful sores and scabs, which in severe cases can make a horse lame. Mud fever most commonly affects the pastern and heel area but can also affect the upper leg, the belly, and in some cases the neck area (also known as Rain Scald). Non-pigmented skin tends to be more severely affected.

Famous quotes containing the words mud and/or fever:

    “Dirty fellow!” exclaimed the Captain, seizing both her wrists, “hark you, Mrs. Frog, you’d best hold your tongue; for I must make bold to tell you, if you don’t, that I shall make no ceremony of tripping you out of the window, and there you may lie in the mud till some of your Monseers come to help you out of it.”
    Frances Burney (1752–1840)

    Y’know Pete, back where I come from folks call that love stuff “quick poison” or “slow poison.” If it’s quick poison it hurts you all over real bad like a shock of electricity. But if it’s slow poison, well, it’s like a fever that aches in your bones for a thousand years.
    Dalton Trumbo (1905–1976)
