The intestinal helminth fauna of 201 specimens of Vulpes vulpes, captured in Galicia (northwest Spain), was investigated. Eight species were found: Toxocara canis (23% of host specimens), Toxocara cati (0.5%), Toxascaris leonina (1%), Uncinaria stenocephala (28%), Seuratascaris numidica (0.5%), Taenia crassiceps (23%), Mesocestoides litteratus (2.5%) and Dipylidium caninum (0.5%). We discuss possible relationships between human population density and the prevalence of infection of fox by intestinal helminths.
