Association and invasion of Salmonella enteritidis to Caco-2/TC-7 cells preincubated (1 h, 37°C) with EPS produced by L. paracasei CIDCA 8339 and CIDCA 83124 at 30°C in milk.

|---|---|---|---|
| Control | - | 6.07 ± 0.06a | 4.60 ± 0.05a |
| EPS 8339 | 300 | 6.07 ± 0.01a | 4.69 ± 0.09a |
| 500 | 6.14 ± 0.03a | 4.57 ± 0.08a | |
| 800 | 5.49 ± 0.04b | 3.50 ± 0.04b | |
| EPS 83124 | 300 | 6.03 ± 0.12a | 4.63 ± 0.04a |
| 500 | 6.08 ± 0.02a | 4.55 ± 0.11a | |
| 800 | 5.54 ± 0.03b | 3.43 ± 0.08b |
Control corresponds to cells preincubated with DMEM. Different letters within columns indicate significant differences (p < 0.05, Tukey’s multiple comparison test).
