Figure 1

CATH-1 shows effective killing of SS2. Time-killing kinetics of CATH-1 against SC19 (A) and P1/7 (B) are shown. SS2 strain SC19 in mid-logarithmic growth was treated with CATH-1 at 2 × MIC for 2 h. Then, bacterial morphology and ultrastructure were observed by scanning electron microscopy (C) and transmission electron microscopy (D).
