parasites
neoplasia
what are the clinical signs of trauma causing spinal cord disease?

alert, afebrile, good appetite, & localized to a cord segment
how is a vertebral body abscess diagnosed?
radiographs & CSF
what is a common cause of an epidural abscess?
ascending myelitis from tail docking, epidural injections, trauma, & infection
what are the clinical signs associated with an epidural abscess?
febrile, inflammatory leukogram
what is the treatment for trauma related spinal cord disease?
salvage if you can - no drugs
dex, banamine, & phenylbutazone
what is the treatment for an epidural abscess?
….these calves die
maybe antibiotics?? prognosis depends on duration

true
what are the intermediate hosts for parelaphorastrongylus tenuis?
snails & slugs
what is the natural host of parelaphorastrongylus tenuis?
white tail deer
what are the clinical signs of parelaphorastrongylus tenuis?
asymmetrical cord signs, recumbency, but remain BAR
how is parelaphorastrongylus tenuis treated?
ivermectin
fenbendazole (5mg/kg)
dexamethasone & banamine are beneficial
