The S. suis serotype 9 (S9) AgI/II and, to a lesser extent, that of serotype 2 (S2), are bacterial adhesins for extracellular matrix proteins. Adhesion of the S. suis S2 and S9 strains to different concentrations of collagen I (A, B), fibrinogen (C, D), and plasma fibronectin (E, F) as evaluated by ELISA. Data represent the mean ± SEM from at least three independent experiments. *(p < 0.05) and **(p < 0.01) indicate a significant difference between the wild-type or complemented strain (CΔagI/II) and the agI/II-deficient mutant (ΔagI/II).
