Effect of Tween-20 and trypsin treatment on the binding to the MUC2 mucin.
| Bacteria | % binding to MUC2 mucin | ||
|---|---|---|---|
| Control (7H9) | Tween-20 | Trypsin | |
| M. avium 104 | 0 | 47 ± 6∗ | 38.1 ± 4∗ |
| M. avium 3388 | 0 | 54 ± 6∗ | 48.4 ± 5∗ |
p < 0.05 compared to M. avium incubated in the 7H9 broth. M. avium strains were treated with Tween-20 or trypsin for 3 h at 37°C, washed, and incubated with 5% MUC2 mucin. The numbers represent the percent of binding to the mucin.
