A horse with sweet-itch

Summer eczema in horses is seasonal, annually recurring itch that goes hand in hand with dermatitis. This inflammation of the skin is caused by an allergic reaction to the saliva of certain biting midges, Culucoides, who are primarily active round sunrise and sunset during the warmer months (March – October). This reaction causes a constant itch at the man, base of the tail, head and ears which results in chafing. When scratching, horses can injury themselves, which could lead to a secondary bacterial infection.

Not all horses are allergic to this mosquito which is why reaction vary from horse to horse. Breeds such as Iclanders, Shires, Welsh ponies and Frisians appear to be the most sensitive to the allergy while sometimes even certain blood lines within breeds show a higher susceptibility than others. This means that a possible allergic reaction is genetically determined.
