Several <i>S. aureus</i> and other Gram-positive strains incorporate different levels of native LPETG substrate after 24 hrs of incubation.

<p>(A) FACS analysis of 10 MSSA and 10 MRSA <i>S. aureus</i> isolates. All <i>S. aureus</i> strains were incubated in LB medium as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0089260#pone-0089260-g001" target="_blank">figure 1A</a>. (B) FACS analysis of a selection of Gram positive bacteria. The bacteria were cultured in the presence of 1 mM native or scrambled LPETG substrates during 24 hrs in TSB medium. Bacteria were washed, re-suspended in PBS and analysed with FACS. Bacterial strains used are depicted on the x-axis. Abbreviations used are described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0089260#pone-0089260-g001" target="_blank">figure 1</a>. These are the representative images of independently performed FACS analysis in triplicate with the SEM depicted.
