The worms mate inside the host, in which the females also lay their eggs, to be passed out in the host's feces into the environment to start the cycle again. N. americanus can lay between nine and ten thousand eggs per day, and A. duodenale between twenty-five and thirty thousand per day.
It was in the 1950s that it was established that whipworms have direct life cycle, required no other animals (vectors or intermediate hosts for their transmission) and rather fragile eggs unlike most other helminths. [15] It is now known that all whipworm species have a similar general life cycle. [2] [24] Whipworm eggs are first ingested by ...
