  1. Superscripts differ within plasmid a,b (P < 0.05).
  2. Superscripts differ between plasmids x,y,z (P < 0.05).
  3. Stability of luminescent Salmonella typhimurium with three different plasmids (pAK1-lux, pXEN-1, and pCGLS-1); Percent emitting and non-emitting evaluations at day 0, 6, and 10 of in vitro culturing without ampicillin selection.
