Figure 1
Effect of serotype switching on S. suis CPS expression. (a) Hydrophobicity of the different S. suis strains/mutants. Very low surface hydrophobicity is indicative of high encapsulation, which is demonstrated in the previous study27. Data are expressed as mean ± standard error of the mean (SEM) (n = 3). An asterisk denotes a significant difference with SS2 by Mann–Whitney rank sum test (p < 0.05). (b) Transmission electron micrographs showing CPS expression of the different S. suis strains/mutants. Scale bars = 0.5 µm.
