Growth curves of thiazolidione derivatives against planktonic bacteria of E. faecium EF16M64 in sub-MIC concentrations. The E. faecim EF16M64 was treated with a H2-60 and b H2-81 at 1×, 1/2×, 1/4×, 1/8×, and 1/16× MICs for 24 h. The growth of their planktonic cells was determined by optical density at 600 nm (OD₆₀₀). Data (means ± SDs) were performed in triplicate independently
