Question

Which of the following is an example of nemathelminthes?
A. Ascaris
B. Pinworm
C. Hookworm
D. All of the above

Answer 1

The Aschelminthes are an obsolete phylum of pseudocoelomate and other similar species, closely affiliated with the Platyhelminthes, which are no longer considered closely related and have been promoted to phyla in their own right.

Complete answer:
Bilateral symmetry and pseudocoelom are available for Ascaris, pinworm and hookworm. They are a triploblastic parasite in humans which causes diseases. These are the features of the Nemathelminthes phylum.
Ascariasis, which is a species of roundworm, is an inflammation of the small intestine caused by Ascaris lumbricoides. Roundworms are a type of worm with parasites. There are fairly common infections caused by roundworms. The most common roundworm infection is Ascariasis.
Pinworm infection, also known as enterobiasis, is a pinworm-induced human parasitic disease. Itching in the anal region is the most common symptom. This can complicate sleeping. The period of time from egg swallowing to fresh eggs emerging around the anus is 4 to 8 weeks.
Hookworms are intestinal, parasitic roundworms that cause forms of infection known as helminthiases, which are blood-feeding. In countries with limited access to sufficient water, sanitation, and hygiene, it is a widespread infection.
So, the correct answer is ‘all of the above’.

Note: A roundworm called Ascaris lumbricoides infects the small intestine of a human and functions as a parasite, receiving nutrients from the intestinal tract of its host. A type of parasite known as a soil-transmitted helminth (STH) is ascaris lumbricoides, along with whipworm and hookworm.
