Equine: Reportable Dz's Flashcards
What dz’s require the vet to be accredited by which organization to collect/submit samples for testing. Can VT’s assist, fill out forms and hand in?
EIA - vets must be accredited. VT’s can assist w/ blood collection, fill out form but must be double checked + signed by accredited dvm b4 submission. Sample to accred. lab
What is EIA?
Equine infectious anemia AKA Swamp Fever. A viral dz spread by biting flies, mosquitos, repeated needle use and dental floats
Symptoms = anemia, thrombocytopenia, weight loss, lethargy, edema, petechia/ecchymosis
Asymp = reservoir for infection
In regards to EIA, where is it most common. What is the surveillance program? Any vx, tx?
AB and SK most common.
No well-established surveillance program - horses tested ‘voluntarily’ local stables/show grounds may require it
neg coggins req to leave CAD and return, coggins good for 6mo from date of collection
no vx, no cure
When a horse is positive for EIA, what happens?
Immediate quarantine of facility, watch for petechia/ecchymosis
ELISA or AGID (coggin’s test)
all horses on property including those there in the previous 30 days are also traced and tested
if pos, horse is culled
owners may be compensated
How do you test for coggins?
blood collected in red top and submitted with form
An ELISA may be run first -> faster, detects antibodies earlier but is more sensitive = more false positives
therefore, all pos confirmed with coggin’s test (AGID test)
What is the AGID test, how long does it need to run, what is a pos vs neg?
Serum - 48 hours
precipitation of antibodies and antigen
pos = hexagon shape
neg = triangle shape
What is vesicular stomatitis?
viral dz,zoonotic
symptoms = mild fever, painful blisters, hypersalivation (mouth, lips, prepuce, udder, coronary bands)
Transmission by biting insects, in/direct contact w/ infectious fluids
no vx licensed for use in eq
Not fatal, done in 2-8d
last found in CAD in 1949
What are some reportable dz in CAD, what about NOT in CAD?
CAD - Anthrax, brucellosis (fistulous withers, poll evil)
Not CAD - African horse sickness, VEE, Contagious equine metritis(stallions asymp carriers. Infertility/abortion in mares), equine piroplasmosis (tick born, imported from endemic countries tested)
