[Prokaryotic expression of pilA gene of type I pilus of enteropathogenic Escherichia coli isolated from ducks and the immunoprotection effect of recombinant expression protein challenged with virulent strains].


A pair primer was designed by Oligo 6.0 according to the pilA gene sequence of E. coli isolated from human in GenBank. The pilA Gene was obtained by PCR with the enteropathogenic E. coli isolated from ducks as template and cloned into pMD18-T vector. It was identified by PCR, restriction endonuclease analysis, DNA sequencing and then subcloned into BamH I… (More)
