How long does a whipworm stay in its host? |
[Edit] |
Answer
Whipworms have a direct life cycle, which means that no other animal is involved as a host.
An infected animal passes the eggs in the feces. It takes approximately one month for the infective larvae to develop in the eggs.
The larva is ingested by another animal (usually a dog). The larvae hatch and burrow into the wall of the lower small intestine (jejunum and ileum). The larvae go through four molts (growth stages) over the course of about 3 months, until they become mature adults capable of reproducing.
During this time they move down to the large intestine (cecum and colon). Here they attach to the wall by their thread-like heads, leaving their thicker bodies extending into the intestinal space.
Each female worm can produce over 10,000 eggs each day of her life, and she can live for several years
