27

Correct diagnostic technique for spirocerca lupi

"Canine and feline esophageal worm"

Observing "paper clip-shaped eggs" on fecal flotation

28

Correct diagnostic technique for dioctophyma renale

"Canine giant kidney worm"

Observing large, rough, bipolar, barrel-shaped eggs on urine sedimentation (after centrifugation)

29

Correct diagnostic technique for Trichuris vulpis

"Canine whipworm"

Observing bipolar, football-shaped eggs in fecal flotation (eggs do not float well, therefore they must be allowed to float for a minimum of 15 minutes before viewing under microscope)

30

Correct diagnostic technique for filaroides osleri

"Canine lungworm"

Observing infective first-stage larvae with S-shaped appendage on the tail on fecal flotation

31

Correct diagnostic technique for dirofilaria immitis

"Canine heartworm"

Observing of microfilariae in blood samples using modified Knott's test in conjunction with commercially available ELISA

32

Correct diagnostic technique for stephanurus dentatus

"Swine kidney worm"

Observation of strongyle-type eggs in pig urine

33

Correct diagnostic technique for oesophagostomum dentatum

"Nodular worm of swine"

Standard fecal flotation or necropsy revealing large nodules within the wall of the large intestine

34

Correct diagnostic technique for oxyuris equi

"Equine pinworm"

Cellophane tape impressions of anus revealing larvated eggs

35

Correct diagnostic technique for ollulanus tricuspis

"Feline trichostrongyle"

Flotation of feline vomitus revealing infective third-stage larvae

36

Correct diagnostic technique for trichinella spiralis

"Trichina worm in pigs"

Microscopic examination of muscle biopsy revealing encysted larvae in muscle tissue

 

37

Pathology produced by physaloptera species

"Canine and feline stomach worm"

Adult nematodes firmly attached to the stomach mucosa; blood suckers

38

Pathology produced by toxocara canis

"Canine and feline ascarids"

Physical blockage of the lumen of the small intestine

39

Pathology produced by trichuris vulpis

"Canine whipworm"

Blood suckers; tiny stylet in the tip of the whiplike anterior end cannulates blood vessels

40

Pathology produced by filaroides osleri

"Canine lungworm"

Formation of nodules at the bifurcation of the trachea

41

Pathology produced by gongylonema pulchrum

"Esophageal worm of ruminants"

Parasite lies embedded in esophageal submucosa in a zigzag fashion

42

Pathology produced by setaria equina

"Equine abdominal worm"

Nonpathogenic; solitary worms are found free within the abdominal cavity

43

Pathology produced by ancylostoma caninum

"Canine and feline hookworm"

Adult nematodes firmly attached to the mucosa of small intestine; voracious blood suckers

44

Pathology produced by oxyuris equi

"Equine pinworm"

Pruritus in the anal region; hairs at base of tail broken off from attempts at scratching anus

45

Pathology produced by spirocerca lupi

"Canine esophageal worm"

Formation of nodules in the esophagus

46

Pathology produced by dioctophyma renale
