The purpose of this study was to investigate and update the spatial distribution of spp. in wild boars tested between 2015 and 2022 and to test the correlation of the population density of chosen animals (wild boars, red foxes (), raccoon dogs (), and European badgers ()) with the prevalence of spp. in wild boars in Poland. In addition, to understand the distribution of infected animals, we sought to see if there were a correlation of spp. infections in wild boars with land cover type. Among the wild carnivore species analyzed, only the population density of the raccoon dog ()-an invasive alien species-was significantly associated with infection rates in wild boars, particularly at the regional scale. As scavengers and competent reservoir hosts for all four European species, raccoon dogs are likely to play a key role in the sylvatic transmission cycle. The positive rate of spp. infection in wild boars during 2015-2022 was 0.22%, compared to 0.3% in 2009-2016. Moreover, forest density was positively correlated with infection rates, underlining the role of forest habitats in sustaining transmission.
本研究的目的是调查并更新2015年至2022年期间接受检测的野猪体内 spp. 的空间分布情况，并测试选定动物（野猪、赤狐（）、貉（）和欧洲獾（））的种群密度与波兰野猪体内 spp. 患病率之间的相关性。此外，为了解受感染动物的分布情况，我们试图查看野猪体内 spp. 感染情况与土地覆盖类型之间是否存在相关性。在所分析的野生食肉动物物种中，只有外来入侵物种貉（）的种群密度与野猪的感染率显著相关，尤其是在区域尺度上。作为所有四种欧洲 物种的食腐动物和合适的储存宿主，貉很可能在野生动物传播循环中发挥关键作用。2015年至2022年期间野猪体内 spp. 的感染阳性率为0.22%，而2009年至2016年为0.3%。此外，森林密度与感染率呈正相关，突出了森林栖息地在维持 传播中的作用。
