Testing and Control
Vaccine research, EIAV/FIV
What does it mean to Me?
Primary Pathology Mature RBC’s destroyed by immune system
Maturation of RBC precursor cells prevented
Other EIAV Symptoms
Depression Fever Enlarged Lymph Nodes Weakness Weight Loss Anorexia Edema Nasal Discharge DEATH
So now you know…..
What EIAV is and what it means for the horse.
But what are we doing about it? Mandatory Testing
Federally Mandated Control Measures Vaccine Research
Current Testing • Agar gel immunodiffusion test (AGID or Coggin’s)
• Competitive enzyme-linked immunosorbant assay (cELISA)
AGID / Coggin’s
cELISA
What this means is…
70% of horses that contract EIAV would
effectively manage the infection….
But…..
100% of horses who have a positive Coggin’s Test
will die as a result of the test.
