Taenia multiceps (Leske, 1780) is a taeniid cestode that in its adult stage lives in the small intes-~ ine of dogs and other canids. The metacestode, previously known as Coenurus cerebralis, is usually found In t~ e nervous system incl~ ding brain and spinal card in sheep and other ruminants. The presence of cysts typlcally leads to neurologlcal symptoms that in the majority of cases result in the death of the animai from starvation after some weeks. Coenurosis could cause high losses in sheep farms because the disease affects young animals that the farmers grow up each year as replacements of the older individuals. Coenurosis is also a zoonosis with mare than 100 human cases described in literature, of which the last in Italy and almost 5 reparted in Sardinia. In the last years, the popularity of coenurosis has increased in sheep breedings because of the necessity to operate a differential diagnosis from another neurological disease, scrapie, particularly in atypical cases of coenurosis that could occur also in adult (2-3 years of age) sheep.
