Ashworthius sidemi, a nematode belonging to the family of Trichostrongylidae, is a primary parasite of the Asian deer, mainly sika deer (Cervus nippon), with which it was introduced to Ukraine, as well as Slovakia, the Czech Republic and France. Migrating red deer carried this parasite from neighboring countries to Polish territory. Until now, in Poland, this parasite has been recorded in European bison, red deer, roe deer and fallow deer. As a result of post-mortem examinations of 10 elk, 2 of them from the Augustów Forest and Biebrza Marshes, A. sidemi were found in abomasa for the first time in Poland. The intensity of the invasions was 120 and 7 specimens, respectively. This finding of Ashworthius sidemi in elk indicates a further expansion of the focus of ashworthiosis in BiaŁowieża towards the north into the Biebrza Marshes and the Augustowska Forest. The growth of the elk population and their tendency for long distance migrations can contribute to the spread of the parasitosis in much greater distances than deer. On the basis of our own research and data from the literature, the current spread of ashworthiosis in Poland is discussed.
西德艾氏线虫（Ashworthius sidemi）是毛圆科的一种线虫，是亚洲鹿（主要是梅花鹿，即Cervus nippon）的主要寄生虫，它随宿主被引入乌克兰，以及斯洛伐克、捷克共和国和法国。迁徙的马鹿将这种寄生虫从邻国带到了波兰境内。到目前为止，在波兰，这种寄生虫已在欧洲野牛、马鹿、狍和黇鹿中被发现。通过对10头驼鹿进行尸检，其中2头来自奥古斯托夫森林和别布扎沼泽地，首次在波兰的皱胃中发现了西德艾氏线虫。感染强度分别为120条和7条。在驼鹿中发现西德艾氏线虫这一情况表明，比亚沃维耶扎地区的艾氏线虫病疫源地进一步向北扩展到了别布扎沼泽地和奥古斯托夫斯卡森林。驼鹿数量的增长及其远距离迁徙的习性可能导致这种寄生虫病比在鹿类中传播得更远。基于我们自己的研究和文献数据，本文讨论了艾氏线虫病目前在波兰的传播情况。
