The aim of the study was to supplement the data concerning the spreading of nematode Ashworthius sidemi among wild ruminants in Russia.
The samples of A. sidemi were collected from two fallow deer, which were born and raised in the game farm in Smolensk region (55° 16' N-34° 29' E). The affiliation of the detected nematodes as A. sidemi was made using morphological features (shape of the spicules and the dorsal ray of bursa for males, as well as the presence and shape of the neodont in the buccal cavity for males and females).
The intensity of infection in 2 studied fallow deer was 7 and 19 individuals of A. sidemi. All of the specimens of A. sidemi had the features of juvenile forms. The registration of fallow deer as another one host of A. sidemi in Russia indicates a further spreading of this nematode and confirms the necessity of strengthening the control of this parasite.
The finding of this nematode in non-native captive animals shows the imperfection of control in this sphere. A. sidemi could have been introduced to the game farm both with imported or with native animals due to insufficient quarantine and isolation. More wide further research would be useful in the light of control this potentially dangerous parasite.
本研究旨在补充有关线虫 Ashworthius sidemi 在俄罗斯野生反刍动物中传播的数据。
从两只在斯摩棱斯克地区（55°16'N-34°29'E）的猎场中出生和饲养的黇鹿身上采集了 Ashworthius sidemi 样本。通过形态特征（雄虫的刺和囊的背射线的形状，以及雄虫和雌虫的口腔中的新齿的存在和形状）确定检测到的线虫为 Ashworthius sidemi。
在 2 只研究的黇鹿中，感染强度分别为 7 只和 19 只 Ashworthius sidemi。所有 Ashworthius sidemi 的标本都具有幼体形态的特征。在俄罗斯将黇鹿登记为另一种 Ashworthius sidemi 的宿主表明这种线虫的进一步传播，并证实有必要加强对这种寄生虫的控制。
在非本地圈养动物中发现这种线虫表明在这一领域的控制存在缺陷。由于检疫和隔离不足，A. sidemi 可能通过进口或本地动物传入猎场。鉴于控制这种潜在危险寄生虫的需要，进一步广泛的研究将是有用的。
