Parasites of Foxes 
Eucoleus aerophilum (Creplin, 1839) Duj. 1845. 
(Synonym: Trichosoma aerophilus Creplin, 1839.) 
Trachea of Vulpes vulpes. 
Filaria vulpis Comper. 
Rudolphi questions whether this worm, reported by P. Comper as from the 
abdomen of a fox, was not merely a wandering ascarid from the intestine. 
Habronema grimaldiae Seurat, 1915. 
From stomach and intestine of the Algerian fox, V. vulpes atlantica. 
Ollalanus tricuspis Leuckart, 1865. 
From the tunic of the stomach of the cat; reported also for the fox. 
Rictularia affinis Jagerskiold. 
Type specimens from the Egyptian fox; Seurat (1915) reports it for the 
Algerian fox, F. vulpes atlantica. 
Spirocerca subaequalis Seurat, 1915. 
From stomach of Algerian fox. 
Spiroptera sanguinolenta Rud. 1819. 
(Synonyms: Strongylus lupi Rud. 1809; Filaria sanguinolenta Schneider, 
1866.) 
In tumours in the stomach and oesophagus of various Canidae, including 
foxes. Embryos in the blood. 
Spirura gastropkila (Mueller, 1895). 
Seurat (1918) found this species in the Algerian fox. 
Strongyloides longus (Grassi, 1885). 
Intestine of fox, Russia. Romanovic (1914). 
Strongylus vulpis Rud. 1819. 
Bremser reported finding in the mesenteric glands of the fox a worm which 
Rudolphi lists with others under the heading “Entozoa vel Generis dubii, vel 
fictitia.” It remains unknown. Obviously it cannot belong to the genus 
Strongylus as now delimited. 
Trichinella spiralis (Owen, 1835) Railliet, 1895. 
The fox is susceptible to infestation by Trichinella spiralis. Griiner (1916) 
describes trichinosis in captive wild animals including Vulpes lagopus. 
Trichocephalus depressiusculus Rud. 1809. 
(Synonyms: Trichocephalus vulpis Frolich, 1789; Mastigodes vulpis Zeder, 
1803.) 
I have found this in 12 per cent, of the foxes examined. It is reported 
frequently in the literature as occurring in these hosts.
