Abstract
Eggs of Trichuris muris hatched in the cecal contents of mice. A new method was used to calculate the volume changes in the eggs and larvae during hatching under simulated in vivo conditions. Previously quiescent larvae were activated and performed a series of purposeful movements within the egg that resulted in the head and stylet penetrating one of the polar plugs. In the final stage prior to emergence from the egg, there was significant swelling of the eggs due to endosmosis, which was critical for successful hatching. The hatched larvae were also significantly bigger than the resting larvae. Some observations on egg morphology are made, and a mechanism for hatching of T. muris is described.
