What should you know about staphylococcal folliculitis in horses?

Early lesions may be subtle beneath the coat. With progression, the horse can develop clusters of pimples, scabs, oozing areas or hair loss. The back, neck, girth area and other sweaty or rubbed regions may be involved, but distribution varies. A horse may rub or resent grooming if the area is itchy or sore. Folliculitis is a condition; Ingrown Hairs, Skin Bumps and Pimples describe findings that can have several causes.

A veterinarian may inspect the coat and skin, assess recent grooming and tack, and collect material from a lesion for testing when the diagnosis is uncertain or treatment has not worked.

Arrange a veterinary examination before applying leftover medicines. Keep the affected area clean and dry, pause equipment that rubs it, and use separate clean grooming tools until the cause is clearer. Do not squeeze pustules or scrub crusts aggressively. Wash hands after handling lesions and clean blankets, pads and grooming equipment as advised.

The veterinarian may prescribe Antibiotics For Skin Infection when bacterial infection is supported, or Topical Antibiotic Therapy for suitable local lesions. Follow the full instructions and keep the horse's environment and equipment clean to reduce recurrence.

Contact a veterinarian promptly when pustules spread, the horse is painful, the skin is hot or swollen, discharge increases, hair loss expands or the horse develops fever, dullness or reduced appetite. Seek urgent veterinary help for rapidly worsening swelling, severe pain, weakness or breathing difficulty. A human skin rash after handling the horse also deserves medical advice, particularly if it spreads or becomes painful.

Ask: Does this look like bacterial folliculitis or another disease? Is a sample needed? Which equipment should be removed or disinfected? How should the lesions be cleaned? When can tack and shared grooming tools be used again? What signs mean treatment is failing?
