is a foodborne parasite whose wildlife reservoirs are represented by carnivores and omnivores with predatory and scavenger behavior. The aim of the present study was to investigate the occurrence of infection in grey wolves () that recolonized the Western Alps from the end of the past century, and discuss the epidemiological role played by this apex predator in the early phases of its return. During the period 2017-2022, diaphragm samples were obtained from 130 individuals collected in the frame of a wolf mortality survey. larvae were found in 15 wolves (11.53%) with a parasite intensity of 11.74 larvae per gram. was the only species identified. This is the first prevalence survey of in wolves recolonizing the Alps. Results suggest that, in this particular biotope, the wolf has rejoined the cycle and has the potential to play an increasingly important role as maintenance host. Arguments in favor and against this perspective are discussed and knowledge gaps highlighted. The calculated larval biomass in the estimated wolf population roaming in Northwest Italy will serve as baseline value to explore possible shifts in the relative importance of wolves as reservoir within the regional carnivore community. Finally, wolves re-colonizing the Alps already appear as sensitive sentinels to monitor the risk of zoonotic transmission by infected wild boar meat.
是一种食源性寄生虫，其野生动物宿主为具有捕食和食腐行为的食肉动物和杂食动物。本研究的目的是调查自上世纪末重新在西阿尔卑斯山定居的灰狼（）中感染的发生情况，并讨论这种顶级捕食者在其回归早期阶段所起的流行病学作用。在2017年至2022年期间，从一项狼死亡调查框架内收集的130只个体中获取了膈肌样本。在15只狼（11.53%）中发现了幼虫，寄生虫强度为每克11.74条幼虫。是唯一鉴定出的物种。这是对重新定居阿尔卑斯山的狼进行的首次患病率调查。结果表明，在这个特定的生物群落中，狼重新加入了循环，并且有潜力作为维持宿主发挥越来越重要的作用。讨论了支持和反对这一观点的论据，并突出了知识空白。在意大利西北部估计的狼种群中计算出的幼虫生物量将作为基线值，以探索狼作为区域食肉动物群落中储存宿主的相对重要性可能发生的变化。最后，重新定居阿尔卑斯山的狼已经似乎是监测受感染野猪肉人畜共患传播风险的敏感哨兵。
