Figure 2. E. faecalis MN1 inhibits the IL-8 response of HVECs to the staphylococcal superantigen TSST-1.

E. faecalis MN1 (1×10⁷ CFU) was incubated with HVECs in the absence and presence of TSST-1 (100 µg/ml) for 6 h. Cell culture supernates were collected and IL-8 was measured by ELISA. *Significantly higher than all other conditions and #significantly lower than medium only control by one-way ANOVA [F(3,29) = 251.2, p<0.0001] and Tukey's post-hoc test. N = 3–6 replicates.
