Characterization of a New Immunosuppressive and Antimicrobial Peptide, DRS-DA2, Isolated from the Mexican Frog, Pachymedusa dacnicolor

Figure 6

DRS-DA2N and DRS-DA2NEQ induce the death of Gram-negative bacteria rapidly. The death of bacteria was measured by the time-killing assay (TKA). Curves representing the amount of surviving bacteria (CFU/mL) in the absence or presence of DRS-DA2N, DRS-DA2NEQ, melittin, or omiganan at their MIC concentrations. The control corresponds to bacteria without any peptide.
