Proteins with decreased expression levels in the SS biofilm, identified by MALDI-TOF/TOF MS.

<p>a) gi number in NCBI.</p><p>b) Theoretical pI was calculated using AnTheProt (<a href="http://antheprot-pbil.ibcp.fr/" target="_blank">http://antheprot-pbil.ibcp.fr/</a>).</p><p>c) Mascot score obtained for the peptide mass fingerprint (PMF). The significance threshold was 70.</p><p>d) Number of peptides that match the predicted protein sequence.</p><p>e) Percentage of predicted protein sequence covered by matched peptides.</p><p>f) Differential protein expression (fold change) of corresponding protein between <i>Streptococcus suis</i> planktonic and bioflm proteome.
