Abstract：
Sarcoptic mange or scabies is a contagious parasitic skin disease that affects a wide range of domestic and wildlife species. A cross-sectional study was carried out to determine the prevalence, molecular identification, and characteristics of sarcoptic mange in vicuñas. A total of 3,274 vicuñas were examined. Following ritual harvesting events (\"chaccus\") in 13 Andean communities. The presence of mange mites was determined by the skin scraping technique and confirmed by PCR analysis using specific primers for the ITS2 gene of Sarcoptes scabiei. The presence of mange mites was also confirmed by microscopy using samples taken from wallows. A data collection form was used to register the characteristics of the vicuñas sampled. The prevalence of sarcoptic mange was 4.9% (95% CI: 4.1 - 5.6%). All samples from wallows tested positive (9/9). Importantly, the presence of the species S. scabiei was molecularly confirmed. Adult females with regular body condition were more susceptible to sarcoptic mange, although the lesions were mild. This study confirms the presence of S. scabiei in semi-captive vicuñas and points to the possible role of wallows in the dissemination of Sarcoptes mites.
摘要：
Sarcoptic或sc疮是一种传染性寄生性皮肤病，会影响各种家庭和野生动植物物种。进行了横断面研究以确定患病率，分子鉴定，以及维库尼亚斯的沙眼mange的特征。总共检查了3,274个维库尼亚。在13个安第斯社区举行的仪式收获活动（“chaccus”）之后。通过皮肤刮擦技术确定and螨的存在，并使用针对Sarcoptesscabiei的ITS2基因的特异性引物通过PCR分析进行确认。使用取自wallows的样品，通过显微镜也证实了螨螨的存在。使用数据收集表格来记录采样的维库尼亚斯的特征。沙眼manage的患病率为4.9％（95％CI：4.1-5.6％）。来自wallows的所有样品测试为阳性(9/9)。重要的是,在分子上证实了S.scabiei物种的存在。身体有规律的成年女性更容易受到沙眼的影响，虽然病变较轻。这项研究证实了半圈养的vicuñas中存在S.scabiei，并指出了walls在Sarcoptes螨传播中的可能作用。
