Chorioptic mange caused by Chorioptes bovis is a common pruritic skin condition of the horse. This surface-browsing parasite usually affects the lower legs (leg mange) but can present as a generalized skin disease. Numerous anecdotal reports exist in the literature about the benefit of lime sulphur as a treatment for surface ectoparasites in the horse. This report studies the use of lime sulphur when applied as a 5% solution, some with and some without prior shampooing and clipping, to treat confirmed cases of chorioptic mange in 22 horses. Horses included in the trial had clinical signs indicative of chorioptic mange and positive identification of chorioptic mites on skin scrapings and tape preparations. Each horse was treated with sulphurated lime dip solution four times at 7-day intervals. Most horses were clipped and/or shampooed prior to treatment. Animals were assigned a score based on a scale of 1-10 to assess the severity of their lesions and degree of behavioural signs. The horses were again scored and examined for mites after four treatments. All animals showed a reduction in scores at the end of the trial and mites were not demonstrated from any animal.
由牛蠕形螨引起的马皮肤鳞癣是马常见的瘙痒性皮肤病。这种在体表寄生的寄生虫通常会影响马的小腿（腿部疥癣），但也可能表现为全身性皮肤病。文献中有许多轶事报道称石硫合剂对治疗马的体表外寄生虫有益。本报告研究了将石硫合剂配制成5%的溶液，部分马匹在用药前进行了清洗和剪毛，部分未进行，以此来治疗22例确诊为皮肤鳞癣的马匹。纳入试验的马匹有皮肤鳞癣的临床症状，且在皮肤刮片和胶带涂片检查中确诊有牛蠕形螨。每匹马每隔7天用硫化石灰浸液治疗4次。大多数马匹在治疗前进行了剪毛和/或清洗。根据1至10分的评分标准对动物的病变严重程度和行为症状程度进行评分。在4次治疗后，再次对马匹进行评分并检查是否有螨虫。试验结束时，所有动物的评分均有所降低，且未在任何动物身上发现螨虫。
