Abstract

The Iberian lynx (Lynx pardinus) population has been increasing in recent years thanks to the collaboration of several associations within the framework of the Life Lynxconnect project, which promotes captive breeding for the subsequent release of specimens into the environment. It is therefore important to know their population status, the diseases to which these animals are exposed, and how they affect their repopulation. In this sense, this study aims to study how the presence of mycobacteria affects the lynx population in Extremadura (southwest of Spain). To this end, blood samples, tracheal swabs, and tracheobronchial washings from live-captured lynxes, as well as mediastinal and mesenteric lymph nodes from roadkill animals, were collected. The association between the presence of mycobacteria and various factors-including body condition, age, sex, and blood parameters-was subsequently evaluated. Up to date, our findings show the absence of tuberculosis (TB) in all lynxes tested, while they seem to be reservoirs of non-tuberculous mycobacteria (NTM), mainly M. lentiflavum, the most isolated species. Nonetheless, these mycobacteria appear to have no significant effect on the health condition of the animals.

伊比利亚猞猁非结核分枝杆菌的鉴定及其对其健康的影响。
近年来,伊比利亚猞猁(lynx pardinus)的数量一直在增加,这要归功于“生命Lynxconnect”项目框架内几个协会的合作,该项目促进了圈养繁殖,以便随后将标本释放到环境中。因此,重要的是要了解它们的种群状况、这些动物所暴露的疾病以及它们如何影响它们的再繁殖。从这个意义上说,本研究旨在研究分枝杆菌的存在如何影响埃斯特雷马杜拉(西班牙西南部)的猞猁种群。为此,收集了活体捕获的猞猁的血液样本、气管拭子和气管支气管洗涤液,以及被公路撞死动物的纵隔和肠系膜淋巴结。分枝杆菌的存在与各种因素(包括身体状况、年龄、性别和血液参数)之间的关系随后被评估。到目前为止,我们的研究结果表明,在所有测试的猞猁中没有结核病(TB),而它们似乎是非结核分枝杆菌(NTM)的宿主,主要是M. lentiflavum,这是最分离的物种。尽管如此,这些分枝杆菌似乎对动物的健康状况没有显著影响。
