Coenurosis, also known as caenurosis, coenuriasis, gid or sturdy, is a parasitic infection that develops in the intermediate hosts of some tapeworm species (Taenia multiceps,[1] T. serialis,[2] T. brauni, or T. glomerata). It is caused by the coenurus, the larval stage of these tapeworms. The disease occurs mainly in sheep and other ungulates,[3] but occasionally can occur in humans by accidental ingestion of tapeworm eggs. Adult 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.[4] Humans cannot be definitive hosts for these species of tapeworms. In wild animalsAlthough coenurosis is more commonly associated with domestic animals, it has also been documented in wildlife, such as in mountain ungulates in the French Alps. It is believed that the ungulates are being contaminated by infected sheepdogs. Understanding how this disease is transmitted from sheepdogs to wild animals is important in managing the spread of this potentially dangerous zoonotic disease. A potential management strategy would be for farmers to properly dispose of carcasses that they find on their land. In wild gelada monkeys in Ethiopia, coenurosis was found to affect the fitness of these primates[5][6]. Mortality increased and fertility was inhibited. The disease has also been documented in wild sheep and other ruminants and rarely documented in rodents, horses and cats. Very few cases have been identified, but this could be the result of limited research on wild coenurosis. Animals infected with the disease tend to hide or take cover from predators and therefore may not be seen by humans. See also
