Flashcards in cestodes, trematodes, hints Deck (14):
1

taenia solium: transmission and disease

ingestion of larvae encysted in undercooked pork, or ingestion of eggs.
if you ingest the larvae, you get an intestinal infection. if you ingest the eggs, you get cysticercosis or neurocysticercosis.
tapeworm

2

taenia solium: treatment

praziquantel for ingestion of eggs and cysticercosis. albendazole for neurocysticercosis

3

diphyllobothrium latum: transmission, disease, and tx

ingestion of larvae from raw freshwater fish. causes B12 deficiency and anemia b/c tapeworm competes for B12 in the intestine
treat with praziquantel

4

Echinococcus granulosus transmission, disease, and tx

ingestion of eggs from dog feces
cuases hydatid cysts in the liver. they may cause anaphylaxis if antigens are released, so surgens preinject with ethanol to kill cysts before removal.
treat with albendazole.

5

What is the transmission, disease, and tx of schistosoma?

snails are the host. flukes can penetrate human skin. causes liver and spleen graunlomas, fibrosis, and inflammation. chronic infection with schistosoma hematobium can cause squamous cell CA of the bladder. treat with praziquantel

6

Clonhorchis sinensis: transmission, disease, and tx

transmitted by undercooked fish
cuases biliary tract inflammation and pigmented gallstones. associated with cholangiocarcinoma.
treat wtih praziquantel

7

parasite associated with biliary tract disease, cholangiocarcinoma

clonhorchis sinensis

8

parasite associated with brain cysts and seizures

taenia solium

9

parasite associated with hematuria and bladder cancer

schistosoma haematobium

10

parasite associated with liver cysts

echanococcus granulosus

11

parasite associated with microcytic anemia

necator

12

parasite associated with vitamin B12 deficiency

diphyllobothrium latum (from raw fresh water fish)

13

parasite associated with portal HTN

schistosoma (mansoni, japonicum)

14

parasite associated with perianal pruritis

enterobius (aka pinworm)
