Taenia infection history and symptoms

Taenia saginata taeniasis produces only mild abdominal symptoms or may not cause any symptoms. However, some people may have abdominal discomfort. The most striking feature consists of the passage (active and passive) of proglottids. Occasionally, appendicitis or cholangitis can result from migrating proglottids. Taenia solium taeniasis is less frequently symptomatic than Taenia saginata taeniasis. The main symptom is often the passage (passive) of proglottids. The most important feature of Taenia solium taeniasis is the risk of development of cysticercosis. People often realize they are infected when they pass segments of the worm in their stool, especially if the segments are moving.
