The antiphagocytic properties afforded to S. suis by CPS types 2, 1/2, 14, and 1 appear similar under in vitro conditions. Parental strains and isogenic mutants (1 × 107 CFU/ml) were incubated for 60 min with J774 macrophages (multiplicity of infection = 100) in the presence of 50% murine serum. Results represent the mean (CFU/ml) + SEM of four independent experiments. Statistical analyses using the Student’s t-test showed no significant differences in the number of internalized bacteria between strains.
