The gray fox (Urocyon cinereoargenteus Schreber, 1775) is the most abundant and opportunistic wild canid in Mexico. However, the parasites of this canid in Mexico are poorly known, and an intensive parasite survey is lacking. A survey of gray fox parasitological feces was conducted in El Cimatario National Park, a protected area representative of the seasonally dry, tropical highlands of Mexico. Feces were collected in six 1-km-length transects during the summer of 2003 and spring of 2004. The coproparasitoscopical survey registered nine species of nematodes, typical of wild and domestic canids such as Strongyloides stercoralis, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Dioctophyme renale, Trichuris vulpis, Trichuris sp., and Capillaria sp. Ecological factors such as temperature and humidity appear to play a more important role in the establishment of these species of parasites in this protected area than the presence of domestic dogs.
灰狐（Urocyon cinereoargenteus Schreber, 1775）是墨西哥最丰富和机会主义的野生犬科动物。然而，这种犬科动物的寄生虫在墨西哥知之甚少，缺乏密集的寄生虫调查。在 El Cimatario 国家公园进行了灰狐寄生虫粪便调查，该公园是代表墨西哥季节性干旱、热带高地的保护区。在 2003 年夏季和 2004 年春季，在六条 1 公里长的横截线上收集了粪便。粪便的寄生虫学调查记录了 9 种线虫，这些线虫是典型的野生和家养犬科动物的寄生虫，如粪类圆线虫、窄头副血矛线虫、犬弓首蛔虫、狮弓蛔虫、肾膨结线虫、猫弓首蛔虫、毛首线虫和毛细线虫。温度和湿度等生态因素似乎比家养犬的存在对这些寄生虫在保护区的建立更为重要。
