Absence of capsular polysaccharide is associated with increased surface hydrophobicity of <i>S</i>. <i>suis</i> serotype 2.

<p>Hydrophobicity of wild-type and mutant strains was determined using <i>n</i>-hexadecane. Data represent the mean ± SEM from three independent experiments. *** (<i>p</i> < 0.001) indicates a significant difference between wild-type strains (P1/7 or 89–1591) and their non-encapsulated mutants (Δ<i>cpsF</i> and Δ<i>neuC</i>).
