Effect of overexpression of elr operon on E. faecalis virulence. Kaplan-Meier survival analysis in a mouse peritonitis model with the E. faecalis WT strain (open circles), the ΔelrA strain (squares), and the P+-elrA-E strain (closed circles). A total of 10 mice were infected intraperitoneally with ~3 x 108 (a) or ~1 x 108 (b) CFU of each strain. For pairwise comparisons of P+-elrA-E / WT and P+-elrA-E / WT, P values were < 0.05 for each inoculum
