Phage activity against PJI Staphylococcus aureus isolates. Seven phages were tested against 122 S. aureus isolates. (a) Results of planktonic susceptibility testing using all seven phages. (b) The three phages that yielded plaques or zones of clearance for ≥25% of the bacterial collection in planktonic experiments were evaluated for anti-biofilm activity isolates for which planktonic activity had been observed. This included phage ATCC 11988-B1 (58 bacterial isolates); phage ATCC 19685-B1 (89 bacterial isolates); and phage ATCC 23360-B1 (79 bacterial isolates). The percentage of biofilms susceptible to each phage is shown.
