is the most important food-borne parasite in Europe. Its natural definitive host is the red fox () while other canid species play a secondary role in the maintenance of its endemics. However, recent studies call attention to the potential of golden jackal () as a suitable definitive host for . Our study aimed to evaluate the quantitative and qualitative egg production traits of adult in different hosts as an indicator of reproductive success. Investigation of 111 and 82 parasites from 33 red foxes and 29 golden jackals, respectively, we ascertained that the proportion of worms with mature eggs was significantly lower in golden jackals than in red foxes. Those worms, which produced mature eggs in golden jackal hosts, originated from less crowded infrapopulations than their fox-originated counterparts. Other characteristics of the parasite's reproductive ability, such as the proportion of fertile worms, and mean egg production were similar in the two hosts. Comparing these findings to evolutionary data on different canid taxa, we hypothesised that the mutual presence of red fox and a differently evolved host of might contribute to the formation of stable parasite circulation in these multi-host systems.
是欧洲最重要的食源性寄生虫。其天然终末宿主是赤狐（），而其他犬科物种在其地方病的维持中起次要作用。然而，最近的研究关注到金豺（）作为合适的终末宿主的潜力。我们的研究旨在评估不同宿主中成年寄生虫的产卵数量和质量特征，以此作为繁殖成功的指标。分别对来自33只赤狐和29只金豺的111只和82只寄生虫进行调查后，我们确定金豺体内有成熟虫卵的虫体比例显著低于赤狐。那些在金豺宿主体内产生成熟虫卵的虫体，其所在的群体拥挤程度低于来自狐狸的同类虫体。寄生虫繁殖能力的其他特征，如可育虫体比例和平均产卵量，在这两种宿主中相似。将这些发现与不同犬科分类群的进化数据进行比较，我们推测赤狐和进化不同的宿主的共同存在可能有助于在这些多宿主系统中形成稳定的寄生虫循环。
