Question

Which is not a parasite of the human intestine?
A. Ringworm
B. Pinworm
C. Threadworm
D. Tapeworm

Answer 1

Intestinal helminths and protozoan parasites cause infections, which are among the most common infections in humans in underdeveloped nations. In affluent areas, protozoan parasites are more frequent than helminths in causing gastrointestinal infections. In endemic nations, intestinal parasites cause major illness and mortality. One of the most common types of intestinal parasites are intestinal worms, commonly known as parasitic worms. Intestinal worms come in a variety of forms, including: Ascariasis, pinworm, and hookworm infections are caused by flatworms, which include tapeworms and flukes.

Complete answer:
Option A: Their bodies are long and spherical, and they come in a variety of sizes. Roundworms can dwell in or on humans, causing a variety of issues. They are most commonly found in soil and faeces, and they can enter the body through the mouth or direct skin contact. They can survive for a long time in the human intestine. Normal Flora is the name given to them.
So, option A is correct.
Option B: Pinworm infestations can cause a urinary tract infection (UTI) in women in rare circumstances if the infestation is left untreated. The uterus, fallopian tubes, and other pelvic organs can all be affected by pinworms that move from the anus into the vagina. Other infections, such as vaginitis and endometritis, may arise as a result of this.
So, option B is not correct.
Option C: They infect the intestines of humans (intestines). They are most common in youngsters, but they can afflict anyone of any age. Threadworms live in the gut for around six weeks before dying. Female worms lay small eggs around the anus before dying (back passage).
So, option C is not correct.
Option D: Certain tapeworm eggs can travel outside of your intestines and produce larval cysts in bodily tissues and organs if you eat them (invasive infection). Tapeworm larvae, on the other hand, mature into adult tapeworms in your intestines if you eat them (intestinal infection).
So, option D is incorrect.

Therefore, Option A is the correct answer.
