Survival of C. elegans fed on (A)
E. faecalis OG1RF without or with pCF10 or the Δprg plasmid variants listed, (B) pCF10ΔprgA, pCF10ΔprgC, pCF10ΔprgA-C complemented with their respective genes expressed from the PQ promoter carried on plasmids pMB5, pMB7, or pINY1801. Survival was scored daily and the differences in survival from the control (pCF10) are shown for pCF10ΔprgB (**P<0.01) and for pCF10ΔprgA, pCF10ΔprgC, and pCF10ΔprgA-C (***P<0.001). Each experiment was repeated in triplicate at least 3 times and the average values for a representative experiment are shown.
