How long does whipworm last?
Whipworms pass microscopic eggs in the stool. The eggs are very resistant to drying and heat, so they can remain alive in the environment for up to 5 years. Once laid, they mature to an infective stage (a process known as embryonation) in the environment and are able to re-infect a new dog in 10-60 days.
How long does it take whipworms to hatch?
The eggs mature to an infective state, or embryonate, in the environment, and are ready to re-infect the host or infect a new host in 10-to-60 days. Once ingested, they hatch and mature in the lower intestinal tract, where they attach to feed and lay more eggs, continuing the cycle.
How long do whipworms grow?
The adults attach to the wall of the caecum and the ascending colon. The female adult worm starts to produce eggs 60 to 70 days after infection, and sheds between 3,000 and 20,000 eggs per day. The adult worm usually reaches 3-5 cm in length and has a lifespan of 1-3 years.
