From: Exploration of the role of the virulence factor ElrA during Enterococcus faecalis cell infection
Effect of ElrA expression on E. faecalis envelope (A) Cell wall polysaccharide profiles from the OG1RF, P+-elrA-E and P+-ΔelrA strains recovered in exponential growth phase. Abbreviations: EPA, Enterococcal Polysaccharide Antigen; TA, teichoic acids. (B) Thickness of the polysaccharide pellicle (PS), the intermediate translucent region (ITR) and of the peptidoglycan layer (PG) was measured from electronic microscopy images using Image J software. Three measurements were made per bacteria. Mean values and SEM were calculated on 10 independent bacteria. Statistical analysis was performed using unpaired Student’s t test.
