An epizootiological survey of leishmaniosis, coccidiosis and parasitic helminths in 67 foxes (Vulpes vulpes) was conducted in Guadalajara (central Spain). Examination for parasitic protozoa revealed prevalences of 74% Leishmania (determined by molecular methods) and 2.9% coccidia oocysts (fecal flotation). Survey of parasitic helminths (fecal flotation/necropsy) demonstrated the presence of nine species, including six nematodes, two cestodes and one trematode. Nematodes were the most common parasites of foxes, followed by cestodes and trematodes. Greater levels of nematodes like Uncinaria, with a free-living stage in its life-cycle, were found in foxes in areas where moist soils were likely to exist, in contrast to areas of semiarid characteristics, where Toxascaris leonina or Trichuris vulpis were predominant. With regard to helminths of importance as human pathogens, trichinoscopy revealed the presence of a relatively high number of foxes (8.9%) infected with Trichinella spiralis. Finally, Toxocara canis infection was less frequent (4.4%) than trichinellosis.
在西班牙中部的瓜达拉哈拉，对67只狐狸（赤狐）进行了利什曼病、球虫病和寄生蠕虫的流行病学调查。对寄生原生动物的检查发现，利什曼原虫的感染率为74%（通过分子方法确定），球虫卵囊的感染率为2.9%（粪便浮选法）。对寄生蠕虫的调查（粪便浮选/尸检）显示存在9个物种，包括6种线虫、2种绦虫和1种吸虫。线虫是狐狸最常见的寄生虫，其次是绦虫和吸虫。与半干旱地区以狮弓蛔虫或狐鞭虫为主的情况相反，在可能存在湿润土壤的地区的狐狸中发现了更多生命周期中有自由生活阶段的线虫，如钩口线虫。关于作为人类病原体具有重要性的蠕虫，旋毛虫检查发现感染旋毛虫的狐狸数量相对较多（8.9%）。最后，犬弓首蛔虫感染的频率（4.4%）低于旋毛虫病。
