Fasciolopsis buski

Large Intestinal Fluke

Physiology and Structure

  • Resides in the small intestines.
  • Egg production is initiated 3 months after the initial infection with the metacercariae.
  • Glands within the parasite enable the penetration of soft tissues of snails.











Clinical Syndromes

  • Attachment of the flukes in the small intestines can cause inflammation, ulceration and hemorrhage.
  • Severe infections produce abdominal discomfort, similar to that of duodenal ulcer as well as diarrhea.
  • In rare cases, death occurs.


Treatment, Prevention and Control

  • Drug of choice is praziquantel.
  • Safe consumption of aquatic vegetation, proper sanitation and control of human feces would help to reduce the incidence of that disease.
  • Control of reservoir hosts would also help reduce the transmission of the worm.
