MCQs On Diseases Caused by Helminths

Helminths or parasitic worms are huge macroparasites. When in adult forms, they are visible to the bare eyes. Most of these are intestinal worms, transmitted from the soil affecting the gastrointestinal tract. Some other parasitic worms harbouring the blood vessels are schistosomes. These worms are known to live and feed in the living host, obtaining nutritional requirements and shields while they in turn disrupt the ability of the host to absorb nutrients.
