Abstract

In April 2014 and 2015, we noted localized alopecia (neck, forelimbs, and chest) and hyperpigmentation on two adult brown bears (Ursus arctos) captured in central-south Sweden for ecological studies under the Scandinavian Brown Bear Research Project. In spring 2015, a brown bear was shot because of human-wildlife conflict in the same region. This bear also had extensive alopecia and hyperpigmentation. Ectoparasites were collected from the affected skin areas in all three individuals and preserved in ethanol for identification. Based on morphological characteristics, the lice were identified as Trichodectes spp. and Trichodectes pinguis pinguis. To our knowledge, these are the first reported cases of chewing lice in free-ranging brown bears in Scandinavia.

摘要

2014年4月和2015年，在斯堪的纳维亚棕熊研究项目下，我们注意到在瑞典中南部捕获用于生态研究的两只成年棕熊（棕熊）出现局部脱发（颈部、前肢和胸部）和色素沉着过度。2015年春季，在同一地区，一只棕熊因人类与野生动物冲突被射杀。这只熊也有大面积脱发和色素沉着过度。从所有三只个体的受影响皮肤区域收集了体外寄生虫，并保存在乙醇中用于鉴定。根据形态特征，这些虱子被鉴定为毛虱属和肥胖毛虱。据我们所知，这些是斯堪的纳维亚自由放养棕熊中首次报告的咀嚼虱病例。
