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 wal 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 no prenatal transmission
- there is no transmammary transmission
- there is no hepato-tracheal migration.
The prepatent period is 10-11 weeks.
