Production of FaeG, the major subunit of K88 fimbriae, in transgenic tobacco plants and its immunogenicity in mice.

Transgenic tobacco plants stably expressing recombinant FaeG, which is the major subunit and adhesin of K88ad fimbriae, were obtained. Analysis of sera from immunized mice indicates that in mice, the immunogenicity induced by plant-derived FaeG protein is comparable to that generated with traditional approaches.
