Presence/absence of 25 putative virulence genes represented in a dendrogram. Naming (SSU numbering) is derived from the annotated genome sequence of P1/7 [7]. Presence of 25 described putative virulence factors was studied: muramidase released protein (mrp), and extracullar factor (epf) [13], suilysin (sly) [20], sortases (srtA, srtBCD, srtF) [34], surface antigen one (sao) [42], hyaluronidase (hylA) [17,43], opacity factor (ofs) [37], fibronectin binding protein (fbps) [44], arginin deiminase (arcA) [45], glyceraldehyde-3-phosphate dehydrogenase (gapdh) [46], regulator of virulence (revS) [35,47], enolase (eno) [48], glutamine synthetase (glnA) [49], igA1 protease [36], inosine 5-monophosphate dehydrogenase (impdh) [50], dipeptidyl peptidase IV (dppIV) [51], ferrous iron transporter (feoB) [52], subtilisin like serine protease (sspA) [53], amylopullulanase (apuA) [54], ferric uptake regulator (fur), and adhesion competence repressor (adcR) [55]. * 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).
