What it is and how you avoid it

You hear an article from Horse Canada.com. Sludge fever: what it is and how to avoid it through: Kim Izzo.

It is again this season in which Winters hit spring showers to create an epic sludge season. And with mud season, horses, blankets and election prayer boots come into the stuff. But it's not just messy; For some horses it also brings pasters of dermatitis or “mud fever”.

Diminutive fever, also known as scratches, is a common skin condition that affects the lower limbs, especially the back of pasters and heels. As a rule, it is caused by a longer exposure to moist, muddy environments (pastures and paddocks, we see them), which creates ideal conditions for bacteria and fungi.

Diminutive fever can exist as crusts, inflammation, hair loss and seepage lesions and can cause discomfort or even lameness if they remain untreated. While the primary guilty is usually the bacterium dermatophilus congolensis, other organisms and environmental factors can also contribute to this.

Understanding and combating the basic causes of mud fever is the key to maintaining the health and comfort of a horse. To aid us, we turned to Dr. Kate Robinson, a deputy veterinarian at McKee Pownall in Ontario. And as with any health problem or treatment, owners should always obtain advice from their regular veterinarian before treating their horse.

Horse Canada: What is mud fever?

Dr. Kate Robinson: Diminutive fever is an inflammatory disease of the distal extremity in which the superficial skin layers are involved. It is most common on the palmar or plantar surface of the pastern region and typically affects white legs (but every color can be affected). Affected limbs develop areas of crust/oozier lesions that are often red and painful. The skin can crack and thicken in chronic or more severe cases. Lesions can spread around the front of the limb and go higher. This can be a sign of a more stern disease, which is referred to as pasters -Leukocytocytocation -Vasculitis (PLV).

Sludge fever is a diverse disease in which bacteria, fungi and viruses are involved as contributing etiological lively ingredients. In some cases, sunlight or photosensitization can play a role. Also excess moisture or abnormal moist/desiccated cyclists can contribute to this (think of the morning grass). After all, there can be allergic or environmental factors in the game, since some horses repeatedly develop mud fever and then stop having breakouts to another farm when moving.

How is mud fever treated?

Since several etiological lively ingredients may be involved, several treatments and/or combination treatment may be required.

For gentle cases, I recommend cutting out the hair from the region to enable more precise operate of topical treatment. Carefully immaculate the area with a gentle disinfectant like blue chlorhexidine solution. If the horse allows it, carefully remove all crusts that become softer and easily emit. Some horses are quite painful with mud fever (regardless of the severity) and require sedation for treatment. After cleaning and removing cushioned crusts, desiccated the area and apply a generous layer of penaten® ointment for gentle cases. This is repeated at least once a day.

Earnest cases, chronic cases or cases that do not respond to gentler treatment can require a prescription ointment. These are often stricter ointments that contain a soothing zinc oxide, steroid to control inflammation, antibiotics and antifungals. In addition, I will sometimes prescribe a course of systemic (normally oral) inflammation substances (NSAIDS or Steroids) and antibiotics in particularly hard cases, with the idea of ​​treating the skin from inside and outside. Hospital stays and special care for the solution may rarely be required.

It can be a good idea to keep inside a few days at the beginning of the treatment to reduce exposure to solar and moisture and keep the area immaculate. Alternatively, wraps/bandages can be placed over the affected area, but in turn becomes problematic if they are moist/filthy.

How can mud fever be prevented primarily?

Prevention can be hard because so many factors can be involved. In horses in which sunlight and/or excess moisture are identified as factors, efforts should be made to avoid them. Changed turnout plans and the operate of boots or wraps can be helpful, although boots/wraps are unusable with moist and catch moisture against the skin.

Otherwise, regular care for removing mud and rubble and drying the skin/hair can be helpful. The operate of a barrier cream such as Penaten® can possibly be protective in horses who have previously suffered from mud fever, but is not recommended for horses without illness.

Maintaining the paddock and turnout, so that they are as desiccated and immaculate as possible, can make a major contribution to prevention. This can mean that material (bed linen, pea gravel, mats) is added to build lower areas and/or to aid keep them desiccated.
