Tapeworms

Tapeworms

• A. Tapeworms
• B. Hookworms
• C. Roundworms
• D. Whipworms

Answer: (A)

Tapeworms are flat, segmented parasites (cestodes) that attach to the intestinal lining with a scolex and release proglottids containing eggs. Their segmented body, lack of a true digestive system, and reliance on absorbing nutrients through the surface surface to survive set them apart from the other options, which are nematodes with tubular bodies and distinct digestive tracts. Hookworms, roundworms, and whipworms have different life cycles and egg forms and typically cause different clinical signs. In practice, tapeworm infection is suggested by finding proglottids or Tapeworm eggs in feces and by history of ingesting intermediate hosts (like fleas for Dipylidium). This combination of morphology (segmented, flat body) and life cycle differentiates tapeworms from the others, making them the correct choice.
