  1. 3. Centrifugal flotation is the diagnostic technique of choice for concentrating nematode eggs passed in feces; this depends on the fact that nematode eggs XXXXX in a concentrated salt or sugar solution.
  2. 6. Dipylidium and Taenia belong to this group of helminths.
  3. 8. This rather large nematode is found in the lumen of the small intestine after undergoing a liver-lung migration; eating eggs containing infective larvae can infect dogs and cats.
  4. 9. Ocular and visceral XXXXX migrans can be caused by zoonotic transmission of Toxocara and Baylisascaris.
  5. 10. This genus of tapeworm is relatively harmless unless it begins to multiply asexually in the peritoneal cavity of dogs; we still don't know how/why this happens!
  6. 13. Dogs aquire this parasite when they eat undercooked crayfish (or “crawfish” if they are in the south). Enter the genus only.
  7. 16. If a dog ingests raw salmon or trout infected with this parasite, it can acquire a fatal bacterial infection (Neorickettsia helminthoeca).
  8. 17. Nanopheytus belongs to this group of helminths
  9. 18. The Baermann procedure is the preferred diagnostic technique for these parasites, but it’s very important to use fresh feces that hasn't been contaminated with non-parasitic larvae!
  10. 19. Transplacental transmission ensures that virtually every newborn of this species is infected with Toxocara
  11. 20. The diagnostic XXXXX of Toxocara canis is an undeveloped or unembryonated egg in fresh feces.

  1. 1. The XXXXX is the primary location for the adult stage of Dirofilaria immitis in dogs and cats.
  2. 2. The name for a mature tapeworm segment containing eggs; seeing these structures on the perianal region or in animal bedding is often how we diagnose Dipylidium caninum.
  3. 4. Dogs and cats get this tapeworm when they eat the infected intermediate host (wild birds and mammals).
  4. 5. If a cat ingests an infected snail or rodent (intermediate or paratenic hosts), this nematode matures to the adult stage in the lungs.
  5. 7. Fleas are the intermediate XXXX for Dipylidium This parasite is acquired when dog or cat eats an infected flea.
  6. 11. The species of Toxocara that matures to adults in the small intestines of dogs.
  7. 12. The XXXX of Echinococcus and Taenia tapeworms passed in the feces of dogs look identical, but only Echinococcus is zoonotic.
  8. 14. Ancylostoma and Toxocara both undergo tracheal migration, also known as liver XXXX migration, to complete their life cycle.
  9. 15. This blood-sucking nematode is transmitted when infective larvae in the environment penetrate thru the skin of dogs (or people).
