Methods using in vitro processes are disclosed for inducing or enhancing expression of enteric bacterial antigens or virulence factors. The methods, therefore, produce antigenically enhanced enteric bacteria. Also disclosed are methods for using the antigenically enhanced bacteria, as well as vaccines containing the enteric bacteria. Specifically, a whole enteric bacteria or components thereof are provided by Campylobacter species. In addition to this species there are other enteric bacteria, such as Yersinia spp., Bacteroides spp., Klebsiella spp., Gastrospirillum spp., Enterobacter spp., Salmonella spp., Aeromonas spp., Vibrio spp., Clostridium spp., Enterococcus spp., and Escherichia coli, which are useful for inducing or enhancing expression of enteric bacterial antigens and/or virulence factors.
