Figure 4

Transmission electron micrographs showing internalization of S. suis by DCs. DCs (MOI:1) were incubated with S. suis wild-type strain (WT) or the non-encapsulated mutant (CPS-) for 4 h. (A) Most DCs were free of S. suis or contained very few bacteria when incubated with serum-opsonized WT strain 31533, (B) DCs incubated with serum-opsonized CPS- mutant contained high numbers of internalized bacteria. White arrows show internalized bacteria, scale bar 2 μm. Original magnification 10000 ×.
