Fig 4. SadP1 contributes to the adhesion of human and porcine IEC.

Fig 4

Adhesion to human (Caco-2) and porcine (IPEC-J2) IEC of WT 10 strain of SS2/CC1 and unencapsulated 10Δcps2 mutant and their isogenic sadP mutants (10ΔsadP1 and 10Δcps2ΔsadP1 respectively). Adhesion was expressed as the total number of IEC associated bacteria, including both adherent and intracellular bacteria, proportional to the total number of bacteria added to the IEC infection model. Three independent experiments (i.e.: biological replicates) were performed in triplicate and the combined together. Unpaired Student's t-test was used to compare each ΔsadP1 mutants with its own parental strains (***, p< 0.001; **, p< 0.01; *, p< 0.05).
