  1. a Phage production host used; MRSA t127 represents spa type 127, MRSA t223 represents spa type 223
  2. A titer of 1 × 1010 PFU/mL for UPMK_1 and UPMK_2 was used in both spot test and EOP
  3. The host range and susceptibility of the bacterial isolates were the clear spot (susceptible; S), turbid spot (intermediate; I), and no plaque formation or killing effect detected (resistant; R)
  4. The considered EOP values were EOP > 0.5 for high production, 0.1 < EOP < 0.5 for medium production, 0.001 < EOP < 0.1 for low production, and EOP < 0.001 for very low production
  5. The data were presented as the mean of triplicate independent measurements
