DEVELOPMENT OF ORAL VACCINE CARROT TO PROTECT AGAINST ETEC 987P DIARRHEA IN PIGLET

摘要

A transgenic plant and an oral vaccine containing the same are provided to prevent and treat ETEC(enterotoxigenic E. coli) 987P diarrhea in piglet and improve stability of production of a protein for adhering to the ETEC 987P. An oral vaccine for preventing or treating ETEC 987P diarrhea in piglet comprises a transgenic plant containing a gene encoding FasG protein having the amino acid sequence, derived from ETEC 987P diarrhea, or its fragment or its extract, wherein the gene encoding FasG protein has the nucleotide sequence of SEQ ID NO:3; and the plant is carrot. Fodder additives contain the oral vaccine.
