It was shown that the parasite could be transferred across species to and from dogs by Karl Theodor Ernst von Siebold and Friedrich Küchenmeister in the 1850s and the species was identified as Taenia multiceps (then called Coenurus cerebralis) in 1890. The cause of these cysts was identified as an animal parasite in 1780 by Nathanael Gottfried Leske and Johann August Ephraim Goeze. However, it was only in the 1600s that clearer behavioural and necropsy descriptions were recorded, including the chacteristic brain cysts and early surgical methods of removal. The texts of Hippocrates describe a nervous disease of sheep consistent with the symptoms of gid, comparing its symptoms to epilepsy and describing the accumulation of bad-smelling fluid in the brain. Humans cannot be definitive hosts for these species of tapeworms. The disease occurs mainly in sheep and other ungulates, but it can also occur in humans by accidental ingestion of tapeworm eggs.Īdult worms of these species develop in the small intestine of the definitive hosts (dogs, foxes and other canids), causing a disease from the group of taeniasis. It is caused by the coenurus, the larval stage of these tapeworms. Parasitic disease Different forms of coenurus in sheep and rabbits and an adult wormĬoenurosis, also known as caenurosis, coenuriasis, gid or sturdy, is a parasitic infection that develops in the intermediate hosts of some tapeworm species ( Taenia multiceps, T.
