The eggs are ovoid, around 75μm in length, with a thick outer shell.
Life Cycle
The infective stage of T. leonina is L2, which are found in the egg. The eggs are ingested by the host, hatch, and enter the alimentary tract. The larvae then penetrate the wall of the intestine. The larvae continue to develop and mature into adults. The adults live in the lumen of the intestine. In the host there is:
