FIG. 1.

Plasmid pK3 enhanced the survival of S. enterica serovar Typhimurium ST3744 in egg albumen. (A) Survival of ST3744 transformed with plasmid pK3 or the vector pRB3-273C in egg albumen. ST3744 transformed with either plasmid pK3 or the vector pRB3-273C was incubated with egg albumen at 37°C. The survival of bacteria was determined and plotted against incubation time. At least three experiments were performed, and the results of a representative experiment performed in triplicate are shown. The error bars indicate standard deviations. (B) Open reading frames identified in the insert of plasmid pK3.
