Between 1983 and 1997, a low incidence of seasonal allergic dermatitis was diagnosed in sheep in Israel aged eight months to eight years, in 10 flocks of a variety of breeds, but not the local Awassi breed. The 40 affected animals reacted with scratching, biting and vigorous stamping of the feet from April to November each year. The principal skin lesions were hyperkeratosis, spongiosis and infiltrations of eosinophils and mononuclear cells, typical of an allergic dermatitis which was probably a hypersensitivity reaction to biting insects. The epidemiological findings in relation to the area of Israel affected, the breeds of sheep and the distribution of the lesions suggested that the sheep's hypersensitivity was due to the bites of several species of Culicoides.
1983年至1997年间，在以色列8个月至8岁的绵羊中诊断出季节性过敏性皮炎的发病率较低，涉及10个不同品种的羊群，但不包括当地的阿瓦西品种。每年4月至11月，40只受影响的动物会出现抓挠、啃咬和用力跺脚的反应。主要皮肤病变为角化过度、海绵形成以及嗜酸性粒细胞和单核细胞浸润，这是过敏性皮炎的典型表现，可能是对叮咬昆虫的过敏反应。与以色列受影响地区、绵羊品种和病变分布相关的流行病学调查结果表明，绵羊的过敏反应是由几种库蠓叮咬引起的。
