Final

Question 1

Which test is best for nematode eggs?

Answer 1

fecal flotation

Question 2

Which test is best for coccidian oocysts?

Answer 2

fecal flotation

Question 3

Which test is best for giardia cysts?

Answer 3

Fecal flotation in sugar or salt
media; iodine can help in visualizing
cysts but kills trophozoites

Question 4

Which test is best for trematode eggs?

Answer 4

sedimentation technique

Question 5

Which test is best for cestode eggs?

Answer 5

Fecal flotation as long as specific
gravity is high enough

Question 6

Which test is best for mites?

Answer 6

typically a skin scrape

Question 7

which test is best for larval tapeworms (e.g. hydatid
cyst, cysticerci, etc.)?

Answer 7

Typically noted at necropsy in the
intermediate host (Definitive Host
will pass eggs!)

Question 8

which test is best for lungworm larvae?

Answer 8

Typically Baermann technique

Question 9

which test is best for Cryptosporidium spp. in young
calves?

Answer 9

acid fast staining

Question 10

life stage passed into environment from Strongyloides stercoralis (in
dogs)

Answer 10

L1 larvae

Question 11

life stage passed into environment from Strongyloides spp. (in
ruminants)

Answer 11

larvated egg

Question 12

life stage passed into environment from “Strongyle”-type eggs (e.g.
genera including
Haemonchus, Cooperia,
Trichostrongylus,
Ostertagia,
Oesophagostomum, etc.)

Answer 12

unlarvated egg

Question 13

life stage passed into environment from Cystoisospora sp. (in small
animals) and Eimeria spp.
(in ruminants)

Answer 13

unsporulated oocysts

Question 14

life stage passed into environment from Giardia spp. (multiple
hosts)

Answer 14

Cysts (trophozoites die quickly in the
external environment)

Question 15

life stage passed into environment from Tritrichomonas foetus (in
large and small animals,
wildlife/exotics, etc.)

Answer 15

Trophozoite (this is the only life stage!)

Question 16

nematodes

Question 17

Baylisascaris procyonis: Digestive

Question 18

pigs

Answer 18

• ascaris suum (GI tract, liver lungs), flotation, host ingests larvated eggs, coughed up and swallowed, L4 molts, clinical signs: milk spots
• trichinella spiralis: nematode never sees outside environment, host ingests meat containing encysted larvae, zoonotic.
• metastrongylus sp.: pig lungworm, nematode, earthworm intermediate host (ingests L1)
• hematopinus suis: sucking louse, skin: (jowl, flanks, inside legs),
• sarcoptes scabei: sarcoptiform mite, skin, winding burrow - this is the ufo looking mite!
