Summary

In the present paper the ultrastructure of the subcuticulare zone of the tegument ofFasciola hepatica and the distribution of thimidine-H3 for establishing the localization of DNA-synthesis in the tegument was studied.

There were two types of subcuticular cells: 1) non-differentiated cells with presence of incorporated labelled thimidine in nuclei presented by DNA non-stable macromolecules, and 2) differentiated or definitive subcuticular cells without aggregates of silver grains.

The results showed a high level of DNA replication leading to mitotic activity of the non-differentiated cells and absence of mitotic activity in the definitive cells.

There was a morphological similarity between non-differentiated cells and the cells from the medular zone, supposing a relationship in their origin.
