The MICs reported were averaged over three biological replicates. The HOU503 (LiaRW73C LiaST120A) DAP MIC was 3 μg/mL, and the FOS MIC was 128 μg/mL.
The selected mutations shown do not include those observed in the no-drug control isolates or the initial starting ancestor. Two isolates were not included due to contamination issues.
The “Additional mutations” column includes occurrences of van operon (vanRSHAXYZ) loss. All isolates lost both van operon copies.
