SALMONELLA TYPHI TY21A EXPRESSING YERSINIA PESTIS F1-V FUSION PROTEIN AND USES THEREOF

摘要

Described herein is the generation of a plasmid construct for expression of a Yersinia pestis F1-V fusion protein. In the disclosed plasmid, the F1-V fusion protein coding sequence is operably linked to the E. coli htrA promoter, and is fused in-frame to the E. coli HlyA secretion signal sequence. Also described is Salmonella enterica serovar Typhi strain Ty21a containing the F1-V fusion protein expression plasmid, such as for use as an oral vaccine against plague.
