Coenurosis
The coenurosis ( Coenurosis , rotating disease ) is an enzootic occurring parasitic disease of the brain , especially in sheep . Human infections are also rare, especially in Asia and Africa.
Pathogen
The causative agent of the disease is Coenurus cerebralis , the fin of the dog's quesen tapeworm ( Taenia multiceps ). The bubble-like, walnut to egg-sized fins ( "bubble worm") move in the upper or cerebellum of the sheep and each contain 500 to 700 scolex equipment. As a space-occupying process, they cause the nervous tissue to die .
Clinical picture
The disease is mostly chronic and leads to neurological disorders such as a disturbed general condition, fatigue , walking in circles ("turning sickness"), reduced threatening reflex , unsteady gait and tilted head posture .
The diagnosis is practically impossible to make in living animals. The CSF may show an increased leukocyte content in the blood one can eosinophilia occur. A reliable diagnosis is only possible by means of computed tomography , but in practice this is not carried out in sheep.
Combat
Drug therapy is not possible. Theoretically, the fins can be surgically removed from the brain, but this is hardly ever realized in practice. The control therefore aims at hygiene measures, in particular the regular deworming of dogs.
