1 GASTRIC NODULE CAUSED BY SPIROCERCA LUPI IN A RED FOX (VULPES VULPES) A. Diakou 1, E. Karamanavi 2, E. Kaldrimidou 2 1 Laboratory of Parasitology and Parasitic Diseases, 2 Clinic of Pathology, Faculty of Veterinary Medicine, Aristotle University of Thessaloniki, Greece

2 Red Fox (Vulpes vulpes) The largest species within the genus Vulpes, living in a wide range of habitats Solitary animals that do not form packs Essentially omnivores, mostly eat rodents, eastern cottontail rabbits, insects, fruit They help to control populations of their prey animals

3 Case report Adult red fox (V. vulpes) for post mortem examination Nodule (2 x 3 cm) on the gastric wall (fundus)

4 Thick-walled cystic granuloma in the submucosa of the gastric wall

5 Incision of the gastric nodule revealing a number of nematodes (The cause of death of the fox was determined as poisoning)

6 Nematodes Nematodes - Bright red, thick - Males <4 cm, females <7.5 cm - Mouth opening surrounded by six lobes - Spirally coiled hind end of male - Bursa with unequal spicules - Vulva close to hind end of the oesophagus - Uterus with characteristic eggs Spirocerca lupi Spirocerca lupi x μm

8 Spirocerca lupi Order: Spirurida Family: Spirocercidae Male: cm Female: cm Cosmopolitan Lesions: esophageal or gastric granulomas, aortic scars and aneurysms

9 Spirocerca lupi Life cycle

10 Greece: S. lupi in 2-24% of the dogs The first case of a gastric nodule caused by S. lupi in a red fox in Greece Epidemiological significance: cross infection between wild and domesticated animals is possible
