Analysis of nuclease activity on DNase agar plates after the transformation of the early S. aureus isolate with low nuclease activity of patient 1 with the plasmid pCM28nuc. (A) The early S. aureus isolate with low nuclease activity (Figure 4, isolate17) shows minimal clearance zones (white arrow) around colonies. (B) The pCM28nuc-transformed early S. aureus isolate exhibits large clearance zones, (C) similar to the corresponding late S. aureus isolate with high nuclease activity (Figure 4, isolate 81).
