Description:Under a low magnification, this photomicrograph depicted the “scolex”, or head region of the cestode, Taenia saginata tapeworm. It is with the suckers on its scolex that the tapeworm attaches itself to the small intestinal mucosa where it will reside.

The scolex of T. solium contains four large suckers and a rostellum containing two rows of large and small hooks. There are usually 13 hooks of each size. The scolex of T. saginata has four large suckers but lacks the rostellum and rostellar hooks.
Clinical Features:

Taenia saginata taeniasis produces only mild abdominal symptoms. 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.
