Table 2. Evaluation of the role of Ebp pili in E. faecalis cell–cell adherence by fluorescence imaging of plates containing GFP-tagged and non-fluorescent colonies.

GFP-tagged OG1RF (SD234) and OG1RF : : gfpΔebpABC (TX5761) cells were mixed with either piliated or non-piliated OG1SSp (TX5756). Values indicate the mean percentage ± sd.

Cells mixed	Mixed colonies (%)
OG1RF : : gfp+OG1SSp	12.85 ± 1.2
OG1RF : : gfp+OG1SSpΔebpABC	7.1 ± 1.6*
OG1RF : : gfpΔebpABC+OG1SSp	6.8 ± 1.3*
OG1RF : : gfpΔebpABC+OG1SSpΔebpABC	1.8 ± 0.9*
