Greek: gaster = stomach;discoides = disk-like. Latin: hominis = belonging to humans; aegyptiacus = Egyptian. English: Amphistomal fluke.

Geographic Distribution/Epidemiology

In India, Indochina, Java, Philippines, Japan about five to ten millions of humans are infected according to the estimations of the WHO. Horses in North Africa.

Morphology/Life Cycle

The digenetic flukes G. hominis and G. aegyptiacus reach a size of 5–10 × 5 mm and parasitize in humans in the colon respectively in horses (G. aegyptiacus). Their shape is characterized by a circularly enlarged posterior body region. The ventral sucker is placed like in all other amphistomid flukes at the posterior end (see Paramphistomum). The life cycle runs similar to that of Fasciolopsis buski. Rats and pigs function as “reserve hosts.”

Symptoms of Disease

Only in cases of mass infections diarrheas are initiated.

See Fasciolopsis buski, since most criteria and characteristics are very similar.
