Q

Xor
✅
1. Fasciola lives in the intestine of infected man.

A
18
Q
  1. Fasciola lives in the bile ducts of infected man
A

True

19
Q

Fascioliosois is caused by ingestion of encysted metacercaria in fish muscles

A

False

20
Q
  1. Fascioliasis is caused by ingestion of encysted metacercaria in contaminated raw vegetables and water
A

True: The disease is indeed caused by ingestion of encysted metacercaria found in contaminated raw vegetables and water

21
Q
  1. Fascioliasis can cause cholecystitis
A

True: Fascioliasis can lead to inflammation of the gallbladder (cholecystitis) due to the migration of the parasites

22
Q
  1. Fascioliasis can lead to lithiasis
A

True: It can lead to the formation of gallstones (lithiasis) as a result of the irritation and inflammation caused by the parasites

23
Q

Fascioliasis can cause pancreatitis

A

True: In some cases, Fasciola infection can lead to pancreatitis due to obstruction of the pancreatic duct

24
Q
  1. Fascioliasis can cause cholangitis & cholecystitis
A

True: The infection can cause cholangitis (inflammation of the bile duct) and cholecystitis due to the presence and migration of the parasites

25
Q
  1. Fasciola infection causes eosinophilia & hepatomegaly
A

True: Fasciola infection often leads to eosinophilia (increased eosinophils in the blood) and hepatomegaly (enlargement of the liver

26
Q
  1. Fasciola species are the only cause of Halzoun in man
A

False: Halzoun can be caused by both Fasciola species and the parasite Linguatula serrata, which is a different entity

27
Q
  1. Halzoun is caused by Fasciola or by Linguatula serrata
A

True: Halzoun syndrome can result from ingestion of either Fasciola or Linguatula serrata

28
Q

Halzoun is caused by eating infected cooked liver

A

False: Halzoun is associated with eating raw liver rather than cooked liver, as cooking usually kills the parasites

29
Q
  1. Halzoun is caused by eating infected raw liver.
A

. - True: Halzoun is indeed caused by consuming raw liver infected with Fasciola or Linguatula serrata.

30
