Measurement of CWH351—656 lytic activity. (A) Relative lytic activity of CWH351—656 against C. difficile, observed as being dose-dependent. Relative activity of 200 µg mL−1 of CWH351—656 was determined as 100%. Error bars represent the standard deviations of two independent assays. (B) Appearance of C. difficile cell suspensions with lysin (C+L) or without lysin (C), photographed over time at room temperature.
