Purpose

The aim of the study was to supplement the data concerning the spreading of nematode Ashworthius sidemi among wild ruminants in Russia.

Methods

The samples of A. sidemi were collected from two fallow deer, which were born and raised in the game farm in Smolensk region (55° 16ʹ N–34° 29ʹ 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).

Results

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.

Conclusion

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.

俄罗斯在小鹿(Dama dama)中首次发现反胃线虫 Ashworthius sidemi

目的

该研究的目的是补充有关线虫Ashworthius sidemi在俄罗斯野生反刍动物中传播的数据。

方法

A. sidemi的样本是从两只小鹿身上采集的,它们在斯摩棱斯克地区(55° 16ʹ N–34° 29ʹ E)的狩猎场出生和长大。使用形态特征(雄性的针状体和滑囊背线的形状,以及雄性和雌性颊腔中新齿动物的存在和形状)将检测到的线虫与A.sidemi联系起来。

结果

2 只被研究的小鹿的感染强度为 7 只和 19只 A. sidemi个体。A. sidemi的所有标本都具有幼体的特征。小鹿在俄罗斯被登记为A.sidemi的另一个宿主表明这种线虫的进一步传播,并证实了加强控制这种寄生虫的必要性。

结论

在非本地圈养动物中发现这种线虫表明该领域的控制不完善。由于检疫和隔离不足, A. sidemi可能与进口动物或本地动物一起被引入游戏农场。鉴于控制这种潜在危险的寄生虫,更广泛的进一步研究将是有用的。
