Intestinal helminths of the red fox (Vulpes vulpes L.) in Galicia (Northwest Spain).

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.
