BACKGROUND
Thelazia callipaeda (Spirurida, Thelaziidae) is a vector-borne zoonotic eye worm with a broad host spectrum. In Europe, it is an emerging threat, having greatly expanded its geographical distribution during the past two decades. In Romania, T. callipaeda has been previously reported in domestic and wild canids and felids. The aim of the present study was to assess the occurrence of T. callipaeda in mustelids in the country.
METHODS
Between March 2015 and April 2019, 77 road-killed mustelids (3 pine martens, Martes martes; 6 European polecats, Mustela putorius; 13 beech martens, Martes foina; and 55 European badgers, Meles meles) were examined by necropsy. If present, all ocular nematodes were collected and stored in absolute ethanol, for subsequent morphological and molecular identification.
RESULTS
Two animals were found to be infected with T. callipaeda: one European badger and one beech marten. The molecular analysis revealed a 100% nucleotide similarity to T. callipaeda haplotype h1 for all the sequenced specimens.
CONCLUSIONS
To our knowledge, the present study demonstrates for the first time the occurrence of T. callipaeda in mustelids from Romania, records the easternmost locality of the parasite in Europe, and represents the first report of T. callipaeda in the European badger, Meles meles, extending the known host range for this parasite in Europe.
背景
Thelazia callipaeda（旋尾目，Thelaziidae）是一种具有广泛宿主谱的经媒介传播的人畜共患眼虫。在欧洲，它是一种新出现的威胁，在过去二十年中，其地理分布大大扩大。在罗马尼亚，T. callipaeda 以前在国内和野生动物犬科和猫科动物中报告过。本研究的目的是评估该国貂属动物中 T. callipaeda 的发生情况。
方法
2015 年 3 月至 2019 年 4 月，通过尸检检查了 77 只道路死亡的貂属动物（3 只松貂，Martes martes；6 只欧洲雪貂，Mustela putorius；13 只山猫，Martes foina；和 55 只欧洲獾，Meles meles）。如果存在，所有眼部线虫都被收集并储存在绝对乙醇中，以便随后进行形态学和分子鉴定。
结果
发现有两只动物感染了 T. callipaeda：一只欧洲獾和一只山猫。分子分析显示，所有测序标本的核苷酸相似度为 100%，与 T. callipaeda 单倍型 h1 相同。
结论
据我们所知，本研究首次证明了 T. callipaeda 在罗马尼亚貂属动物中的存在，记录了寄生虫在欧洲最东部的位置，并首次报告了 T. callipaeda 在欧洲獾，Meles meles 中的存在，扩大了该寄生虫在欧洲的已知宿主范围。
