FIG. 2.

Population sizes of C. jejuni strain RM1221 over time after its inoculation onto radish roots growing in pots in the laboratory and incubation at 10°C. The soil remaining on the radishes after sampling was wiped (□) or gently washed off in water (○). Each data point represents the mean of the log-transformed bacterial population size on six radishes from a total of three replicate pots. The error bars represent ±1 standard error of the mean.
