Filarial nematodes of the Eulimdana genus inhabit subcutaneous tissue of various avian species, mostly Charadriiforme birds. In domestic pigeons, E. clava is the only species recorded in the subcutaneous tissue in a number of isolated cases. In the present study, we discuss the morphology and histopathology of filarial nematodes recovered from subcutaneous tissue of domestic pigeons in Bosnia and Herzegovina. In total 110 pigeons were submitted to necropsy at the Department of Pathology of the Faculty of Veterinary Medicine in Sarajevo. At necropsy, in four pigeons (3.6%) numerous thread-like 0.9-2.1 cm long nematode parasites were observed in the subcutaneous tissue, peritracheal and periesophageal connective tissue. In one pigeon, the parasites were also found free in the body cavity around the heart and lungs. In addition, several 80-90 μm long microfilariae were noted in the tissue cross-sections. No significant lesions were observed associated with adult parasites or microfilariae. Based on morphology, host species and localization detected parasites were identified as E. clava. Molecular analyses of the cox1 and 12S rRNA nucleotide sequences herein generated revealed the close genetic relationship to other filarioid nematodes. The importance of the nematodes in pigeons and the lack of sequences in genetic databases for comparison of avian filarial parasites are emphasized.
尤利姆达纳属的丝虫线虫寄生于各种鸟类的皮下组织，主要是鸻形目鸟类。在家鸽中，棒状尤利姆达纳线虫是在一些孤立病例的皮下组织中记录到的唯一物种。在本研究中，我们讨论了从波斯尼亚和黑塞哥维那家鸽皮下组织中回收的丝虫线虫的形态学和组织病理学。总共110只鸽子被送到萨拉热窝兽医学院病理学系进行尸检。尸检时，在4只鸽子（3.6%）的皮下组织、气管周围和食管周围结缔组织中观察到许多0.9 - 2.1厘米长的线状线虫寄生虫。在1只鸽子中，还在心和肺周围的体腔中发现了游离的寄生虫。此外，在组织切片中还发现了几条80 - 90微米长的微丝蚴。未观察到与成虫寄生虫或微丝蚴相关的明显病变。根据形态学、宿主物种和定位，检测到的寄生虫被鉴定为棒状尤利姆达纳线虫。本文对cox1和12S rRNA核苷酸序列进行的分子分析表明，其与其他丝状线虫存在密切的遗传关系。强调了线虫在家鸽中的重要性以及遗传数据库中缺乏用于比较鸟类丝虫寄生虫的序列。
