Goats were experimentally infected with Sarcoptes scabiei var. ovis from sheep, proving that this mite is not completely host specific. More severe lesions were produced on goats when the mites were applied to lacerated than when applied to scarified or non-scarified areas. Lesions were more pronounced on moistened areas than dry areas, and lesions produced on dry scarified areas resembled those produced on non-scarified moistened ones. Skin scrapings from the experimental lesions in the goats contained numerous mites of all stages, proving that the sheep mites had become well established and were reproducing actively in the experimental lesions. Sever histopathological changes were observed in skin sections, which showed mainly thick scab formation, mites beneath the keratin and severe degenerative and necrotic changes. Treatment of the experimental lesions with Lorexane cream (hexachlorocyclohexane) produced rapid and excellent cure.
山羊通过实验感染了来自绵羊的绵羊疥螨变种，这证明这种螨虫并非完全宿主特异性的。将螨虫应用于划破的部位时，山羊身上产生的损伤比应用于划破或未划破部位时更严重。湿润部位的损伤比干燥部位更明显，在干燥划破部位产生的损伤与未划破湿润部位产生的损伤相似。山羊实验性损伤部位的皮肤刮片中含有各个阶段的大量螨虫，证明绵羊螨虫已在实验性损伤部位很好地定植并活跃繁殖。在皮肤切片中观察到严重的组织病理学变化，主要表现为厚痂形成、角质层下有螨虫以及严重的变性和坏死变化。用林丹乳膏（六氯环己烷）治疗实验性损伤可迅速且出色地治愈。
