What's the procedure for a Wisconsin sugar flotation method of feces evaluation?
Mix 5 grams of feces in sugar solution. Centrifuge with coverslip. Count the # of eggs on coverslip and divide by 5 to get EPG.
Which test is more sensitive: McMaster's or Wisconsin?
Wisconsin
If you don’t see this percentage reduction in EPG with administration of a de-wormer, that’s evidence that there may be resistance.
at least 90%
Does a negative fecal float rule out cestode infection?
No.
Define "refugia."
portion of the parasite population that is not exposed to the treatment

(ie Refugia have not seen the drug, so they should remain largely susceptible to the drug.)
What test is this used for?
a McMaster's test
What is the primary goal of large animal fecal examination and deworming?

What is the secondary goal?
primary goal = to limit environmental contamination (NOT prevent)

secondary goal = limit infection levels in individual animals
What is the most prevalent potentially fatal human disease in North America, and how is it transmitted?
Ehrlichia chaffiensis
Amblyomma americanum (lone star tick)
What is the #1 parasite concern of cattle?
Ostertagia
Define prepatent period.
The time period during which an animal is infected but cannot be detected by organisms shed in bodily materials (feces, urine, etc).
Should you perform a Giardia SNAP test as part of a routine workup on clinically healthy companion animals?
No.
Most Giardia infections are asymptomatic, and it is considered extremely rare to virtually nonexistent that companion animals infect humans with Giardia. Humans are usually infected with different strains of Giardia than companion animals.
