Objective:
To develop attenuated Salmonella which harboring enterovirus 71 (EV71) VP1 gene.
Methods:
The plasmid which expressed VP1 protein of EV71 was constructed by gene recombination. Cellular expression was assessed by Western Blot analysis. The recombinant plasmid was then transformed into attenuated Salmonella SL7207.
Results:
EV71 VP1 gene sequence was inserted into a eukaryotic expression plasmid VR1012. VP1 protein was detected by Western Blot analysis in the culture supernatant. And the attenuated Salmonella harbored the plasmid stable.
Conclusion:
The plasmid was constructed successfully and it can express effectively in vitro. The bacteria which harboring the plasmid were constructed successfully. This has provided a basis for further research of an oral EV71 vaccine.
