Sulfonylurea-mediated inhibition of intracellular replication of B. suis in human macrophage-like THP-1 cells. (A) Growth of untreated cells (•) or growth in the presence of 100 μM MSM (○) or CE (□); (B) dose-response effect in macrophages of 1 μM (open bars) and 10 μM (hatched bars) MSM compared with that of no treatment (filled bars). Standard deviations of the means of two experiments performed in triplicate are represented (**, significant for P < 0.001; ***, significant for P < 0.0001).
