Intracellular survival of S. suis within DCs. DCs were infected with S. suis (MOI:1) wild-type strain (WT) or the non-encapsulated mutant (CPS-) and phagocytosis was left to proceed for 1 h. Antibiotics were then added for a period time of 1 h (considered here as time 0). This initial antibiotic-treatment was lengthened for different times up to 5 h and cells were lysed to quantified intracellular bacteria by viable plate counting. The results are expressed as CFU recovered intracellular bacteria per mL (means ± SEM obtained from three independent experiments using DCs derived from nine different animals). An asterisk indicates the incubation time for which the number of intracellular bacteria recovered is significantly different (p < 0.05) from number of intracellular bacteria obtained after an initial 1 h antibiotic treatment (considered here as time 0).
