1. Those with oriented motion is of infectious oncosphere.

2. Conclusion 45W-4B antigen of Taenia solium oncosphere induces good immune protection in pigs.

3. There are two areas in the oncosphere, area of three pairs of hooks and the glandular cells.

4. Taenia solium 45WB2 protein is a membrane combined protein of oncosphere and plays an essential role in penetrating and forming cyst in pig tissues.

5. Analysis indicate EG95 were a family of gene, which may specifically expresses at the oncosphere life-cycle stage.

6. The objective of this study was to understand the morphological characters and surface ultrastructure about oncosphere and cysticercus of Taenia asiatica(T. asiatica).
