Presence/absence of 25 putative virulence genes represented in a dendrogram. Naming (SSU numbering) is derived from the annotated genome sequence of P1/7 . Presence of 25 described putative virulence factors was studied: muramidase released protein (mrp), and extracullar factor (epf) , suilysin (sly) , sortases (srtA, srtBCD, srtF) , surface antigen one (sao) , hyaluronidase (hylA) [17,43], opacity factor (ofs) , fibronectin binding protein (fbps) , arginin deiminase (arcA) , glyceraldehyde-3-phosphate dehydrogenase (gapdh) , regulator of virulence (revS) [35,47], enolase (eno) , glutamine synthetase (glnA) , igA1 protease , inosine 5-monophosphate dehydrogenase (impdh) , dipeptidyl peptidase IV (dppIV) , ferrous iron transporter (feoB) , subtilisin like serine protease (sspA) , amylopullulanase (apuA) , ferric uptake regulator (fur), and adhesion competence repressor (adcR) . * hylA is present as pseudogene in P1/7 and does not have a SSU-number. '+' indicates all probes have a ratio > -1.5 (present); light grey shading indicates one or more probes have a ratio between -1.5 and -3 (present with slight variation); dark grey shading indicates one or more probes have a ratio between -3 and 4.5 (present with large variation); '-' indicates one or more probes have a ratio < -4.5 (partly or completely absent).
