Which of the following endoparasites of humans does show viviparity ?a...
Trichinellosis is caused by the ingestion of undercooked meat containing encysted larvae of Trichinella species .Trichinella spiralis, a nematode parasite copulates in intestine, after which males dies and females produces larvae which enters into the blood circulation to reach the muscles. After exposure to gastric acid and pepsin, the larvae are released from the cysts and invade the mucosa where they develop into adult worms. The production of larvae indicates vivipary. Ancylostoma, Enterobius and Ascaris are all egg laying endoparasites.

Which of the following endoparasites of humans does show viviparity ?a...
Answer:
Viviparity: Viviparity refers to the reproductive strategy in which the offspring develop inside the female and are born alive.
Among the given options, the endoparasite that exhibits viviparity in humans is Trichinella spiralis.
Explanation:
Trichinella spiralis is a parasitic roundworm that causes trichinosis, a disease characterized by muscle pain, fever, and swelling. It is unique among the given options as it displays viviparity, meaning the female worm gives birth to live larvae instead of laying eggs.
The life cycle of Trichinella spiralis involves the following stages:
1. Ingestion: Humans become infected by consuming undercooked meat containing Trichinella cysts.
2. Larval migration: Once ingested, the larvae are released from the cysts in the stomach and small intestine. They penetrate the intestinal wall and enter the bloodstream.
3. Maturation: The larvae migrate through the bloodstream and reach various tissues, particularly skeletal muscles. Here, they develop into adult worms over a period of several weeks.
4. Reproduction: The female worms release live larvae (viviparity) into the bloodstream, which then travel to other tissues and form cysts.
Overall, Trichinella spiralis is the only endoparasite among the given options that exhibits viviparity in humans.
