Animal sanctuaries are important organisations that promote animal welfare and health as well as social awareness. Following the appearance of several donkeys with severe and distinctive skin lesions in a sanctuary from western Spain in 2021, a multicomponent study was performed to rule out the possible causes. The lesions were mainly concentrated on the extremities and, to a lesser extent, on the face and/or chest. The use of cotton leggings on their extremities as an external barrier to prevent them from bites and treatments with antiparasitic, antiseptic washes and dermatitis lotion showed to be effective measures to improve the donkey lesions. Skin scraping was negative for any relevant causative agents. Histopathological examination of the lesions showed an inflammatory infiltrate at the superficial dermal level, compatible with diffuse chronic dermatitis. A field entomological study was conducted from May to October 2021 to ascertain if any Diptera was responsible for these lesions. Considerable numbers of the stable fly Stomoxys calcitrans were recorded in both sticky traps and decomposing straw bedding. Several species of hematophagous Diptera were also recorded in lower numbers in other traps placed on the farm facilities. According to the entomological data, the location of the bites and clinical signs, it was concluded that S. calcitrans was the main cause of the skin lesions in the donkeys. To our best knowledge, this is the first clinical case of donkeys affected by the stable fly in Spain. For differential diagnosis, a brief discussion of the evidence caused by other biting Diptera groups is provided.
动物庇护所是促进动物福利、健康以及社会意识的重要组织。2021年，西班牙西部一个庇护所出现了几头患有严重且独特皮肤损伤的驴子后，开展了一项多方面研究以排除可能的病因。这些损伤主要集中在四肢，在较小程度上也出现在脸部和/或胸部。在它们的四肢使用棉质绑腿作为防止叮咬的外部屏障，并使用抗寄生虫、抗菌洗液和皮炎洗剂进行治疗，这些措施被证明是改善驴子损伤的有效方法。皮肤刮片检查未发现任何相关致病因子。损伤的组织病理学检查显示真皮浅层有炎症浸润，符合弥漫性慢性皮炎。2021年5月至10月进行了一项现场昆虫学研究，以确定是否有双翅目昆虫导致了这些损伤。在粘性诱捕器和腐烂的稻草垫料中都记录到了大量厩螫蝇。在农场设施上放置的其他诱捕器中也记录到了数量较少的几种吸血双翅目昆虫。根据昆虫学数据、叮咬部位和临床症状，得出结论厩螫蝇是驴子皮肤损伤的主要原因。据我们所知，这是西班牙首例驴子受厩螫蝇影响的临床病例。为了进行鉴别诊断，本文简要讨论了其他叮咬双翅目昆虫群体造成的证据。
