  3. Data are the mean values of four (φ11 and 80α) or three (P22) independent experiments.
  4. aTE, transfer events. TE per donor cell = transductant units (TrU) per ml/6.5 × 107 CFU per ml for S. aureus phages, or transductant units (TrU) per ml/1.0 × 108 CFU per ml for S. Typhimurium phage P22.
