Figure 1
In vitro stability of pcDNA3.1/HA, NA, NP, and pcDNA3.1. Recombinant S. typhimurium containing transfected plasmids were passaged for approximately 100 generations. The percentage of bacteria containing the plasmid was determined by viable count on media without the appropriate antibiotic selection. No significant difference was recorded ().
