Coenurosis

 

a helminthic disease of ungulates, chiefly sheep, and some rodents, characterized by the development of coenuri in various tissues. The coenuri concentrate in the brain (cerebral coenurosis), intermuscular connective tissue, and subcutaneous tissue. The source of the causative agents of the disease are carnivorous animals, chiefly dogs, in whose intestine the mature cestodes are parasitic. The infection is transmitted through water and grass contaminated by the parasites’ eggs.

Cerebral coenurosis is especially dangerous for sheep. The animals circle, throw back their heads, and suffer convulsions and loss of vision. The disease may be fatal.

Coenurosis is treated by surgery only if the infected animal is valuable. Otherwise the sheep are slaughtered. Prevention includes worming sheep dogs and pet dogs and exterminating stray dogs.

The major economic losses associated to coenurosis in small ruminants are abattoir brain condemnation, time and loss of energy to dissect the brain of small ruminants for export purpose (Adane et al., 2015) Shepherds or the owner often facilitate the contamination of the environment by opening the skull of infected sheep leaving the Coenurus cyst free to be eaten by dogs or feeding them directly with the definitive host (Scala and Varcasia, 2006)
Gid (coenurosis) is caused by the larval stage of the canine tapeworm Taenia multiceps, which is called coenurus cerebralis.
