Secondly, all deadstock must be disposed of promptly. Praziquantel is a good choice, which effectively kills the tapeworm and many other worms that can affect livestock. However, by understanding the life cycle, we can effectively control the disease.įirstly, it is imperative to worm all farm dogs at six-week intervals to prevent them from shedding eggs and, hence, infecting sheep. Unfortunately, wormers are not effective when treating clinically diseased sheep with cysts. If the signs are mild, it may be possible to send the sheep to slaughter, but if presented late and in poor condition then often euthanasia is required. However, as vets don’t have an MRI on hand to confirm this, care must be taken by the vet to localise the lesion prior to surgically removing it through a hole in the skull.Īlthough possible, surgery is not often carried out because of the risks and financial implications. This is not without difficulty, great technical skill and some large risks.Ĭysts are most commonly found within the main brain hemispheres. Treatment requires surgical removal of the cyst from the brain. Lambs are mostly affected between six and 18 months and can display neurological signs such as depression, head pressing and a head tilt.Ĭareful examination is necessary to differentiate it from other diseases such as brain abscesses, cerebrocortical necrosis (CCN), and listeriosis. The striking circling behaviour seen in the later stages of the disease are hard to miss, but the early signs can be more subtle and progress slowly. Failure to do so would inevitably result in a spike in cases.įarm dogs should be wormed at six-week intervals to prevent them from infecting sheep © Tim Scrivener What are the signs of gid? It is, therefore, important not to get complacent about worming farm dogs. However, an increase in dog purchases during lockdown has resulted in more dog walkers, which presents a real risk for a resurgence in this previously well-controlled disease. See also: Sheep scab: Symptoms, diagnosis and treatmentĪs improved farm management in recent years reduced the sheep/dog infection cycle, gid has become less commonly seen on farms. When the sheep ingests these eggs, the larval stages then invade the central nervous system and cause a space-occupying cyst. Sheep are commonly infected through grazing pastures contaminated by dog faeces (dogs will only shed eggs if they have eaten the brain of an infected animal, and ingestion by sheep completes the lifecycle). Gid is caused by Coenurus cerebralis, a larval stage of the tapeworm Taenia multiceps, which infests the intestine of dogs and other carnivores. Vet Charlotte Watkins, from Belmont Farm and Equine Vets in Herefordshire, gives advice on dealing with this parasitic disease. A rise in dog walkers on farms presents a real risk for a resurgence of gid cases on sheep farms.
