Figure 2. Total culturable aerobic bacterial abundances on plants that were InocPOS or InocNEG for E. coli O157:H7.

Figure 2

The total aerobic bacterial density enumerated on TSA for inoculated plants with viable E. coli O157:H7 (InocPOS) and those without (InocNEG) averaged for all inoculated plants from 2 to 28 dpi within a field trial. The 0 and 2 hpi time points were omitted due to the presence of large abundance of the E. coli O157:H7; 7 dpi plants were omitted from the E09 trial because enrichment results were not available. An * indicates that significantly more bacteria were found on InocPOS or InocNEG plants by Student’s t-test; P ≤ 0.001.
