**Cestode diseases (Taeniasis, Diphyllobothriasis, cysticercosis, Hydatid cyst disease, hymenolepiasis)

Back 1

1. Into platyhelminthes (flatworms) & Nemathelminthes (roundworms)

Platyhelminthes further breaks down into cestoda (tapeworms) & Trematoda (flukes)

Tell the 1 and 2ndary host of:
2. Taenia solium
3. Taenia saginata
4. Diphyllobothrium latum
5. Echinococcus granulosus

Back 2

1. Cestode
2. 1= human; 2= pigs
3. 1=human; 2= cattle
4. 1=human; 2= copepods and fish
5. 1- dogs; 2= sheep

Front 3

Tell the mode of transmission and sites affected in body
1. Taenia solium (pork tapeworm)
2. Taenia saginata (beef tapeworm)
3. Diphyllobothrium latum (fish tapeworm)
4. Echinococcus granulosus

Back 3

1. Ingest larva in undercoooked pork, intestine
2. Ingest larva in undercooked beef, intestine
3. Ingest larva in undercooked fish, intestine
4. ingest eggs in food or water contaminated by dog feces; live, lungs, brain

Front 4

1. How do you treat all of the cestodes (except echinococcus granulosus?)
2. How do you diagnose the taenia worms?
3. The Diphyllobothrium (fish tapeworm)

Back 4

1. Praziquantel
2. proglottids in stool
3. eggs in stool

Front 5

1. What disease do taenia worms cause?
2. How does the human get the worms?
3. Diagnosed?
4. Treatment?

Back 5

1. Cysticerosis (in animals) from all the cysticerci that form in striated muscle
2. undercooked infected meat
3. proglottids (eggs are less frequent) in stool
4. Praziquantel

Front 6

Taeniasis: usu. asymptomatic, Saginata typically more sx due to size
1. Prevent teniasis?
2. Which of the 2 has mobile proglottids?

Back 6

1. Fully cook beef and pork, and dispose of human waste properly so that cattle and swine cannot consume human feces
2. T. Saginata, the beef tapeworm has mobility. Pork tapeorm T. solium has hooks and suckers

Front 7

5. Prevention?

Back 8

1. Diphyllobothrium latum
2. T. Solium larvae, due to fecal oral contamination and humans taking the position of the intermediate host
3. presence of cyst in tissue via surgical removal or CT

5. Proper hygiene

Front 9

1. What causes the unilocular hydatid cyst disease?
2. What population is it common in?
3. What role do humans play in this life cycle?
4. What causes multiocular hydatid cyst disease?
**cyst fluid contains parasite antigens, may cause anaphylaxis if rupture

Back 9

1. Echinococcus granulossu (dog tapeworm)
