Survival of S. Typhimurium on parsley leaves.
| 4 hours post irrigation | 7 days post irrigation | Change after 7 days | |
|---|---|---|---|
| Strain | Log (CFU/g) ± SD a | ΔLog (CFU/g) ± SD a | |
| w.t. | 6.3 ± 0.2 | 2.8 ± 0.3 | 3.5 ± 0.2 |
| pBcsZ | 6.1 ± 0.3 | 3.9 ± 0.2 | 2.2 ± 0.5* |
| ΔBcsZ | 6.5 ± 0.3 | 2.4 ± 0.4 | 4.1 ± 0.7** |

Numbers represent means of 6 repeats, with standard deviations. Bacterial reduction addresses the delta of log S. Typhimurium counts between 4 hours and 7 dpi.
*A significant difference was observed between pBcsZ and both, w.t. and ΔBcsZ P < 0.001.
**A significant difference was observed between ΔBcsZ and w.t. P < 0.1.
