Ruminant Parasitology

PCC VT program: 1st year Parasitology with Dr. Haveman. Purposly designed for tech students in this class of 2008 to study parasites. Class feel free to make more test for us to practice. I probably will.

Covering ruminant parasitology. This includes all that was on the ruminant test but rephrased and rearraged so that you can't just read the right answer off your test immediately. -I just looked at the test, I don't know whats with on the 1st two Qs. I can't edit them.

  8. Ostertagia has a indirect life cycle and uses the earthworm as its intermediate host
  9. Type ___ Ostertagiasis is seen with uncomplicated infection in the animal with no prior exposure. Type ____ Ostertagiasis is seen in the animals with arrested development in the wall of the abomasum
  10. The ova of above parasite are medium sized TSO in moderate numbers. The prepatent period maybe 3-4wks to 3-4ms.
  11. _______ is a small strongyle that may infect cattle, sheep, goat, and many other species. It is a small, abomasal parasite.
  12. The eggs of the parasite in the above question are very large and can always be easily differentiated from those of Ostertagia and Haemonchus
  13. The parasite in question 11 has a relative that lives in the large intestine and produces large numbers of small ova known commonly as the "bankrupt worm"

  25. One test for lung worm diagnosis is the Baerman test. It uses _______
  26. ______ test we used in class for large animal nematodes on the routine fecal exam, uses Epsom salt as it's flotation media. This is a quanitative test

  28. Fasicola hepatica is the common ______ of cattle, sheep, and goat.
  29. The above fluke uses a snail as its intermediate host.
