1. The ultrastructural changes of sporoblast and sporozoite formation within oocyst of Plasmodium vivax in Anopheles dints was observed by transmission electron microscope.

2. The sporozoite cells are then purified and preserved in liquid nitrogen to make the vaccine.

3. The sporozoite surface antigen CP15 and P23 gene which were successful cloned might be much helpful for the next work of using these genes to develop a immunoprophylaxis or detection technique.

4. This paper summarized the research advance in the live attenuated vaccine, sporozoite vaccine and DNA vaccine.

5. Objective To construct the prokaryotic expression vector of the sporozoite surface antigen gene of Eimeria tenella GZ strain and expression in Escherichia coli.
