Case study (1):

A 36-year-old man suffering from intermittent fever, diarrhea, indigestion and

abdominal pain in the right hypochondrium. Upon examination, he had a slightly
enlarged tender liver and yellow coloration of the sclera. When questioned regarding his
eating habits, the patient admitted to having a fondness for un-cooked watercress and

raw vegetables. An order was written for stool examination for ova and parasites. Blood
sample was collected for complete blood count and liver function tests.
Haematology results showed evidence of anaemia and eosinophilia (60%

eosinophils). The patient's liver enzyme levels were slightly elevated. The diagnosis was
made microscopically after the observation of large, oval, 180X90 u, yellowish-brown,
operculated eggs in the concentrated stool specimen.

QUESTIONS:

1- Which parasite might be causing this infection?

2- Where is this parasite found geographically?

3- Which other helminth lays eggs indistinguishable from the eggs

described in this specimen?

4- How does transmission of this parasite occur?

5- What are the usual symptoms of the disease in humans?

6- How is the diagnosis of this infection usually made?

7- How do you exclude false diagnosis?

8- How is this parasite treated?

9- How can you control such infection?
