Colonization of bean leaf surfaces by Eh299R CUSPER bacteria at different inoculation densities. (a) Changes in population size were monitored as CFUs, normalized per leaf and plotted as a function of time. Inoculation densities (CFUs per leaf) at t=0: (•) 4.5 × 10³; (▪) 6.9 × 10⁴; (▴) 5.7 × 10⁵; and (▾) 1.2 × 10⁷. (b) Increase in population size between t=0 and t=24, that is, N_t=24/N_t=0, as a function of the population size at time t=0. The trendline crosses the x axis at 6.535, which back-transforms to 3.4 × 10⁶ CFU per leaf. The error bars represent standard deviations from the mean.
