The S. suis serotype 9 (S9) AgI/II, but not that of the serotype 2 (S2), is involved in adhesion to porcine tracheal epithelial cells. Adhesion of the S. suis S2 and S9 strains to NPTr cells after 2 h of incubation with a multiplicity of infection of 10. Data represent the mean ± SEM from at least three independent experiments. *(p < 0.05) indicates a significant difference between the S. suis S9 wild-type or complemented strain (S9CΔagI/II) and the agI/II-deficient mutant (S9ΔagI/II).
