Q

Diphyllobothrium

A

pseudophyllidean worm which typically infects humans, dogs, or bears, common in the PNW, Great Lakes, and Canada

18
Q

How many genital pores per segment of Taenia?

A

1

19
Q

Taenia sagninata (beef tapeworm)

A

IH = cattle
DH = humans

20
Q

Taenia solium (pork tapeworm)

A

IH = swine or humans
DH = humans

21
Q

Taenia pisiformis (rabbit tapeworm)

A

IH = rabbits
DH = dogs

22
Q

Taenia hydaginata

A

IH = sheep, cattle
DH = dog, human

23
Q

Taenia lifecycle

A

herbivore ingests eggs from feces, cysticerci develop in tissue, carnivore eats this infectious tissue, develops into adult in small intestine

24
Q

Neurocysticercosis

A

neurological signs in humans due to Taenia solium

25
Q

Taenia solium detection and prevention

A

larvae in muscle at slaughterhouse will have nodules

can also see the cysticerci on underside of pig tongue

26
Q

Where are taenia solium common?

A

free range pigs (and Central and South America)

27
Q

Measly meat

A

due to tapeworms (solium and saginata)

28
Q

Taenia solium clinical signs in humans

A

NEUROLOGICAL

29
Q

Taenia saginata clinical signs in humans

A

diarrhea and weight loss

30
Q

Taenia pisiformis rabbit diagnosis

A

larval cysts (cysticercus) in liver and peritoneal cavity on the viscera; also they’ll have diarrhea and an itchy butt

31
Q

Uniqueness of Taenia multiceps

A

causes larval cysts in the brain, cranium, and spinal cord of intermediate hosts (sheep and goats) which don’t stop growing!

ataxia, circling, blindess

this is the one that looks like that weird sand you had as a kid

32
Q

Smallest taenid?

A

Echinococcus granulosus

33
Q

Definitive host of Echinococcus

A

dogs, coyotes, wolves, and other canids

34
Q

Clinical Signs of Echinococcus granulosus

A

none in definitive host, but intermediate hosts will get large cysts which may rupture in vital organs and can cause sudden death; mainly a problem in sheep

35
Q

Echinococcus multiocularis

A

DH = dog/canid, IH = humans, causes liver disease and death and easily confused with cancer

36
Q

Intermediate host of Dipylidium caninum?

A

fleas and lice

37
Q

What parasite is responsible for butt scootin’ in dogs?

A

Dipylidium caninum (pruritis ani is the vet term for butt scootin’)

38
Q

Anoplocephala eggs

A

unusually shaped, can be square, traingular, etc

39
Q

What type of tapeworm is the exception to praziquantel treatment?

A

Anaplocephalidae - better with benzimadazoles

40
Q

Anoplocephala perfoliata

A

D-shaped eggs, adult worms are gross (duh), collect at ileocecal valve in horses and cause colic

(bonus: intermediate host is mites!)
