MRP-hFg interaction promotes the adherence of S. suis to hCMEC/D3 cells. (A) The adherent ratio of S. suis to hCMEC/D3 cells in the presence of hFg. S. suis 05ZYH33 and 05ZYH33Δmrp mutant were pretreated with a series of concentrations of hFg before infecting a hCMEC/D3 cell monolayer. The adherence ability of S. suis was evaluated by adherence assay. Values represent percent (mean ± S.D.) of total S. suis inoculum bound to the monolayers. (B) The adherent ability of S. suis to hCMEC/D3 cells evaluated by fluorescent microscopy. S. suis 05ZYH33 and 05ZYH33Δmrp mutant were labeled by BCECF (green) before infection, and hCMEC/D3 cell monolayers were treated or untreated with Fg (500 μg/ml). F-actin was strained with Rhodamine-labeled Phalloidin (red), nuclei were stained with DAPI (blue). *P < 0.05.
