Assadov, 1953 was formally described in roe deer and has been reported in a wide range of ruminants, including other Cervidae, as well as Bovidae. Nematode specimens derived from various host species exhibit morphological similarity; however, some differences can be observed. It is unclear if this is due to the differential reaction of one nematode species in different host species (i.e., host-induced changes) or because of distinct nematode species in these hosts (i.e., species complex). This paper focuses on specimens resembling f. and its closely related species ( f. ) collected from various hosts. Morphometric and molecular techniques were applied to assess host-induced changes in nematode morphology and to clarify its systematic classification. There was an overall effect of host species on measurements of nematodes resembling (both males and females), but the distinctiveness of the specimens from cattle were highlighted. The results obtained may suggest that the specimens of from cattle in Germany and cervids in central Europe belong to different strains. Furthermore, nematodes from the cervid strain appear to circulate within particular host species, which can be seen in the stated morphological variations.
阿萨多夫线虫于1953年在狍中被正式描述，并且在包括其他鹿科动物以及牛科动物在内的多种反刍动物中都有报道。来自不同宿主物种的线虫标本呈现出形态学上的相似性；然而，也能观察到一些差异。目前尚不清楚这是由于一种线虫物种在不同宿主物种中的不同反应（即宿主诱导的变化），还是因为这些宿主中存在不同的线虫物种（即物种复合体）。本文聚焦于从不同宿主收集到的类似阿萨多夫线虫及其近缘物种的标本。应用形态测量和分子技术来评估宿主对线虫形态的诱导变化，并阐明其系统分类。宿主物种对线虫（包括雄性和雌性）的测量有总体影响，但来自牛的标本的独特性尤为突出。所获得的结果可能表明，德国牛体内的阿萨多夫线虫标本和中欧鹿体内的阿萨多夫线虫标本属于不同的菌株。此外，鹿科菌株的线虫似乎在特定宿主物种内循环，这可以从所述的形态变化中看出。
