S. aureus Tager 104 Susceptibility to Antibiotic Therapy Demonstrates Predation of Resistance Development. a–d Antibiotic susceptibility testing on sheep blood agar (SBA) plates demonstrated S. aureus Tager 104 is susceptible to linezolid (a), vancomycin (b), erythromycin (c), and oxacillin (d) when challenged with E-test strips. Minimum Inhibitory concentrations shown are: linezolid, 1 μg/mL; vancomycin, 2–3 μg/mL; erythromycin, 0.064 μg/mL; and oxacillin, 0.019 μg/mL. e The effects of vancomycin concentrations on Tager 104 growth were confirmed in solution in 96-well plates and indicate a vancomycin intermediate susceptibility phenotype. This experiment is a combination of 8 replicates and was performed as described in "Methods"
