what spinal disease is common in young large breed, fast growing male horses
cervical vertebral compressive myelopathy “wobblers”
CVCM “wobblers” in horses clinical signs
symmetric ataxia
dysmetria
paresis in all limbs
normal mentation
confirmatory test of wobblers in horses
CT myelography
radiographs only valuable info

- dietary caloric restriction only in growing horses
- cervical vertebral interbody fusion surgery

cause?
clinical signs?
sarcocystic neurona or neospora hughesi
feed contamination via opossum
asymmetric signs of brain/spinal cord (but can cause symmetrical disease)
equine protozoal myeloencephalitis
diagnostic?
