Abstract

The purpose of this study was to investigate and update the spatial distribution of Trichinella 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 (Vulpes vulpes), raccoon dogs (Nyctereutes procyonoides), and European badgers (Meles meles)) with the prevalence of Trichinella 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 Trichinella spp. infections in wild boars with land cover type. Among the wild carnivore species analyzed, only the population density of the raccoon dog (Nyctereutes procyonoides)-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 Trichinella species, raccoon dogs are likely to play a key role in the sylvatic transmission cycle. The positive rate of Trichinella 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 Trichinella transmission.

波兰森林密度和入侵食肉动物与野猪旋毛虫感染有关。

本研究的目的是调查和更新2015 - 2022年野猪中旋毛虫的空间分布，并测试所选动物（野猪、红狐（Vulpes Vulpes）、貉（Nyctereutes procyonoides）和欧洲獾（Meles Meles））的种群密度与波兰野猪中旋毛虫流行率的相关性。此外，为了了解感染动物的分布，我们试图了解野猪中旋毛虫感染与土地覆盖类型是否存在相关性。在所分析的野生食肉动物物种中，只有外来入侵物种浣熊（Nyctereutes procyonoides）的种群密度与野猪的感染率显著相关，特别是在区域尺度上。作为所有四种欧洲旋毛虫的食腐动物和称职的宿主，貉可能在森林传播循环中发挥关键作用。2015-2022年野猪旋毛虫感染阳性率为0.22%，而2009-2016年为0.3%。此外，森林密度与感染率呈正相关，强调了森林生境在维持旋毛虫传播中的作用。
