FIG 3

In vitro plasmid copy number (PCN) and fitness of IncK2 in S. Heidelberg host. (A) IncK2 PCN was determined during a mating experiment between IncK2-carrying populations (SH-2813don) and IncK2-free SH-2813rec populations with and without ampicillin selection. (B) Fitness of IncK2-carrying populations relative to IncK2-free populations under no ampicillin selection (**, P < 0.01). Each bar represents the fitness of one population that was established from one single bacterial colony. The horizontal dashed line represents the fitness of SH-2813rec.
