Explain.

5. Compare the morphological characteristics of the scolices of these 2 species.

6. What is the infective stage? What is the mode of infection?

7. Why is it important to differentiate between these 2 species?

8. How is this infection treated?

9. What is the sure sign of complete cure?

10. How can you control this parasite?

Case study (6):

A 45-year-old man was presented with pain in the upper quadrant of the abdomen. He

had a history of contact with dogs many years ago. On examination, the physician noted

an enlarged liver with a palpable mass in the right hypochondrium. The patient was

submitted for stool, blood and radiological (plain x-ray, CT and MRI) examinations.

Stool examination is negative for ova or parasites. The blood count revealed

eosinophilia (24 % eosinophils). Radiological studies revealed a rounded space-

occupying lesion, 12 cm in diameter in the liver. Microscopic examination of a biopsy

specimen confirmed the diagnosis of the parasitic infection. During surgical removal
of the hepatic cyst, aspiration of the cyst contents was performed and the contents were

also examined microscopically.
QUESTIONS:

1. Based on the patient's symptoms, which parasitic infection do you think he has?

2. What aspect of the patient's history is a clue to his infection?

3. Describe the morphology of this cyst.
