Trichinella nematodes occur in many carnivorous and omnivorous animal species in the sylvatic cycle. Due to their widespread occurrence throughout Poland and diet, free-living Mustelids can act as a potential reservoir for nematodes of the genus Trichinella and play a role in their circulation. The study was designed to determine the presence and predilection sites for Trichinella nematodes in martens (Martes spp.) from the Głęboki Bród Forest District, Poland.

Trichinella britovi larvae were detected by molecular methods in 17.54% examined martens (prevalence: 41.67% among pine martens and 13.88% among Martes spp.). The intensity of infection varied from 0.17 to 37.29 larvae per gram (LPG) (mean 5.43; median 3.4). The highest larval burdens were detected in the tongue in pine martens (Martes martes) and the diaphragm in Martes spp., respectively; the lowest levels were found in the masseter in pine martens and the tongue in Martes spp. No statistically significant difference in the intensity of infection was observed between males and females in either group.

Our findings indicate that T. britovi is present in martens from the Głęboki Bród Forest District, and the predilection sites for the nematode may differ between males and females. However, due to the low number of examined animals, further studies are necessary to confirm whether they are an important element in the maintenance of Trichinella nematodes in the examined area.

旋毛虫的线虫在sylvatic周期中出现在许多食肉和杂食动物物种中。由于它们在波兰和饮食中的广泛分布，自由生活的鼬可作为旋毛虫线虫的潜在贮藏库并在其流通中发挥作用。该研究旨在确定来自波兰格沃博基布罗德森林区的貂（Martes spp。）中旋毛虫的存在和好发部位。

通过分子方法检出的旋毛虫幼虫在检出的貂中占17.54％（流行：松貂中占41.67％，貂属中占13.88％）。感染强度从每克幼虫（LPG）的0.17到37.29不等（平均5.43；中位数3.4）。在松貂（Martes martes）的舌头和Martes spp。的the膜中分别发现了最高的幼虫负担。在松树貂的咬肌和在Martes spp的舌中发现最低的水平。两组中男性和女性之间的感染强度均无统计学差异。

我们的发现表明，来自格本博基布罗德森林区的貂体内存在布里氏锥虫，而线虫的好发部位在雌雄之间可能有所不同。但是，由于受检动物数量少，因此有必要进行进一步的研究，以确认它们是否是检修区内旋毛虫线虫维护的重要元素。
