Vancomycin and linezolid were dosed at 3, 8, 24, and 32 h postinfection. MEDI4893* and R347 were dosed at 3 h postinfection. See Materials and Methods for further details.
The CFU value is significantly lower than that for the R347 control (P < 0.05).
Vancomycin combination therapy is significantly different from vancomycin monotherapy (P < 0.05).
Significantly different from MEDI4893* monotherapy (P < 0.05).
Significantly different from vancomycin monotherapy and vancomycin-MEDI4893* therapy (P < 0.05).
