FIG. 3.

Effect of temperature on the survival of C. jejuni strain RM1221 in the rhizosphere of spinach plants growing in organic soil in the laboratory. After inoculation of C. jejuni into the soil, the plants were incubated at 10°C (□), 16°C (○), 28°C (▵), or 37°C (◊). Each data point represents the mean of the log-transformed bacterial population sizes in two cores comprised of soil and roots that were sampled from two replicate pots at each temperature. The error bars represent ± 1 standard error of the mean.
