FIG 1.

Timeline of MRSA strain isolation over the 5-year period, along with the dates of the 15-day periods of the 600-mg twice-daily (b.i.d.) LZD therapeutic regimen (black arrows). A total of 13 MRSA isolates were included in the study. The name of the MRSA isolate susceptible to LZD is highlighted in gray, and those resistant to LZD are framed in black. Images of isolates cultured on Colombia blood agar plates are presented for 3 isolates, with S. aureus reference strain ATCC 29213 shown for comparison.
