Infections caused by which type of helminth are exemplified by tapeworms?

• A. Nematodes
• B. Cestodes
• C. Trematodes
• D. Protozoa

Answer: (B)

Tapeworms are classified as cestodes, which are a specific group of flatworms characterized by their segmented body structure. Cestodes are known to inhabit the intestines of their hosts, where they absorb nutrients directly through their skin. The segmentation allows for the tapeworm to grow and reproduce efficiently within the host environment. This group of helminths is differentiated from nematodes (roundworms), which have a cylindrical body shape and a different mode of living and feeding. Trematodes, or flukes, are another group of flatworms but are typically leaf-shaped and may have complex life cycles that often include multiple hosts. Protozoa, on the other hand, are single-celled organisms and do not belong to the helminth category. Thus, the association of tapeworms with cestodes is crucial in understanding the different types of helminths and their distinct biological and morphological characteristics.
