Abstract：
Gastrointestinal nematodes and protozoa and other parasite occurrences were evaluated in free-ranging wolf (Canis lupus italicus) and red fox (Vulpes vulpes) populations from natural and anthropized areas of Central Italy. Analyzed fecal samples were collected from 60 foxes and 40 wolves in the anthropized areas, and 41 foxes and 39 wolves in the natural areas. In foxes, hookworm infections (p < 0.0001) were more frequently recorded in the anthropized environment, while coccidia (p < 0.05) and Cryptosporidium spp. (p < 0.0001) were more frequent in the natural area. In wolves, a higher frequency of hookworms (p < 0.0001) was observed in natural areas, while coccidia were more common in the anthropized area (p < 0.05). Moreover, in the natural environment, trichuroid nematodes (p < 0.0001) were significantly more frequent in wolves than in foxes, while Cryptosporidium (p < 0.001) and Giardia duodenalis (p < 0.001) were more common in foxes. In the anthropic area, the occurrence of hookworms was found to be significantly higher in foxes (p < 0.0001), while trichuroid nematodes were more common in wolves (p < 0.0001). The obtained data are indicative of a different diffusion of specific parasite taxa in wolves and foxes living in the natural and/or anthropized environments examined herein.
摘要：
在意大利中部自然和人为地区的自由放养狼（Canislupusitalicus）和红狐（Vulpesvulpes）种群中评估了胃肠道线虫，原生动物和其他寄生虫的发生。从人类地区的60只狐狸和40只狼中收集了分析后的粪便样本，自然地区有41只狐狸和39只狼。在狐狸里,钩虫感染（p<0.0001）更频繁地记录在人类环境中，而球虫（p<0.05）和隐孢子虫。(p<0.0001)在自然区域更常见。在狼中，在自然区域观察到更高的钩虫频率(p<0.0001)，球虫在人物化区更为常见(p<0.05)。此外，在自然环境中，类毛虫线虫（p<0.0001）在狼中的频率明显高于狐狸，而隐孢子虫（p<0.001）和十二指肠贾第鞭毛虫（p<0.001）在狐狸中更常见。在人类区域，在狐狸中，钩虫的发生率明显更高(p<0.0001)，类毛虫线虫在狼中更为常见（p<0.0001）。获得的数据表明生活在本文检查的自然和/或人类化环境中的狼和狐狸中特定寄生虫分类群的不同扩散。
