Fig 3. Virulence of the triple ΔefaCBAΔmntH1ΔmntH2 strain is attenuated in the G. mellonella model.

Percent survival of G. mellonella 72 hours post-infection. Each symbol corresponds to a group of 15 larvae injected with ~ 5 x 10⁵ CFU of E. faecalis. Mean value is shown as a horizontal line. Final 72 hours survival of larvae infected with different strains was compared via ordinary one-way ANOVA with Dunnett’s multiple comparison post-test. (****p ≤ 0.0001).
