Fatty acid supplementation protects liaR-deficient Enterococcus faecalis from high bile challenge. Shown are the averages ± standard deviations for n = 3. (A) Bile supplementation and challenge with 20% bile. All strains supplemented with 0.2% bile had statistically increased numbers of survivors versus those of their unsupplemented counterparts at all time points analyzed (P ≤ 0.001). (B) Oleic acid (OA) supplementation and challenge with 20% bile. All strains supplemented with 20 μg/ml OA had statistically increased numbers of survivors versus those of their unsupplemented counterparts at all time points analyzed (P ≤ 0.023). WT, wild type.
