Abstract：
Tapeworms are trophically-transmitted and multi-host parasites with a complex indirect life cycle, strictly depending on predator-prey interactions. Their presence in a free-living population, mainly definitive hosts, is arduous to study due to the complexity of collecting fecal samples. However, epidemiological studies on their frequency are crucial from a public health perspective, providing information on food habits and prey selection of predators. The present study aims to update the frequency of tapeworms detected in stool samples by molecular analysis in Italian wolf populations of Umbria and Marche regions collected from 2014 to 2022. Tapeworm\'s total frequency was 43.2%. In detail, Taenia serialis was detected in 27 samples (21.6%), T. hydatigena in 22 (17.6%), and Mesocestoides corti (syn. M. vogae) in 2 (1.6%). Three samples were identified as M. litteratus and E. granulosus s.s. (G3) and T. pisiformis, with a proportion of 0.8%, respectively. The low frequency of E. granulosus in a hyperendemic area is discussed. The results show for the first time a high frequency of Taenia serialis not comparable to other Italian studies conducted on wild Carnivora; thus, a new ecological niche is conceivable. These findings suggest a plausible wolf-roe deer cycle for T. serialisin the investigated area.
摘要：
线虫是滋养传播的多宿主寄生虫，具有复杂的间接生命周期，严格依赖于捕食者-猎物的相互作用。他们在自由生活人口中的存在，主要是确定的主机，由于收集粪便样本的复杂性，研究是艰巨的。然而,从公共卫生的角度来看，对其频率的流行病学研究至关重要，提供有关食肉动物的饮食习惯和猎物选择的信息。本研究旨在通过2014年至2022年收集的翁布里亚和马尔凯地区的意大利狼种群的分子分析，更新粪便样本中检测到的tape虫的频率。线虫的总频率为43.2%。详细来说,在27个样本(21.6%)中检测到连续带菌者,22例（17.6%），和MesocestoidesCorti(syn.M.vogae）在2（1.6%）。三个样品被鉴定为马尾藻和S.S.（G3）和T.pisiformis，比例为0.8%，分别。讨论了高流行地区细粒大肠杆菌的低频率。结果首次显示，与对野生食肉动物进行的其他意大利研究相比，连续的Taenia的频率很高；因此，一个新的生态位是可以想象的。这些发现表明，在调查区域中，T.serialisis的狼-of周期是合理的。
