ABSTRACT
Objective:
To clone and express colonization factor antigen Ⅰ(CFA/Ⅰ) of enterotoxigenic Escherichia coli (ETEC) in E.coli DH5?.Methods:
CFA/Ⅰ gene was cloned by PCR from H10407 and recombined to a expression vector pBV220.This vector was designated pBV220- CFA/Ⅰand transformed into E.coli DH5?. The product was tested by SDS-PAGE and immunogenesis test.Results:
The CFA/Ⅰ gene could be expressed in E.coli and contained strong immunogenesis by immune test.Conclusion:
This study paved the way for using ETEC CFA/Ⅰ recombinant as a vaccine candidate in future.
