Scanning electron micrographs showing interactions between DCs and S. suis. DCs were incubated with S. suis (MOI:1) wild-type strain (WT) or the non-encapsulated mutant (CPS-) for 2 h. (A) DCs incubated with S. suis WT strain show very few cocci on the cell surface. DCs incubated with the CPS- mutant show several cocci adhering to the cells (B-C). White arrows show bacterial cells. (A) Scale bar, 10 μm. Original magnification 5000 ×. (B-C) Scale bar, 5 μm. Original magnification 5000 ×.
