How do you prevent the following:
Listeria
Polio
Meningeal Worm
Listeria - hard to prevent, feeding silage that is not rotten
Polio - prevent acidosis, consider sulfur source
Meningial worm - injectable ivermecti, concern GI resistance, prevent deer
What part of the CNS does Listeria effect and what signs will you see?
Brainstem/Cranial Nerve Disease
-Abnormal mentation, unilateral deficit, head tilt, circling, facial nerve deficit
What part of the CNS does polio effect?
Cerebral Disease
-Abnormal mentation

-Opisthotonus
What part of the CNS does meningeal typically affect and what are the signs?
Spinal Cord
-Seasonal
-Normal mentation
-Willing to eat and drink
-Gait deficit, ataxia, cant stand
What is the prognosis for the following?
Listeria
Polio
meningial Worm
General neuro disease
Listeria - Good if treated early, poor if recumbent or severe
Polio- response to treatment critical
Meningial Worm - depend on degree CNS, long time to heal, nerve damage may be permanant
General neuro disease - poor if down and not eating, better up and responsive
How do you treat listeria?
Antiobiotics: Oxytetracying, PPG or Florfenicol
Anti-inflammatory - flunixin
Supportive
How do you treat polio?
Thiamine
mannitol and dexamethasone
What is the dose of thiamine to treat polio?
10mg/kg IM q 6 hours for days, taper

Rabies - necropsy
Necropsy
Fixed brain helpful non rabies
