Effects of Inh2-B1 enhances the bactericidal activity of Ceftriaxone and Cefotaxime. Time-to-kill experiment shows Optical Density (OD) at 620 nm and viable bacterial counts (colony forming units) of (A,B) MW2-WT at different time intervals, when grown in the presence and absence of Inh2-B1 inhibitor. Optical Density and corresponding Colony forming units of (C,D) MW2-WT and (E,F) MW2ΔSTK1 cultures in the presence or absence 50 µM Inh2-B1, 1.51 µM (1 µg/ml) Ceftriaxone, 2.125 µM (1 µg/ml) Cefotaxime, and combination of Inh2-B1 plus Ceftriaxone, and Inh2-B1 plus Cefotaxime. The experiments were carried out as described in the Materials and Method section using Muller-Hinton broth and seeded with 4 × 106 CFUs of S. aureus MW2-Wild type or MW2ΔSTK1 strains per well. Each data points represent Mean ± S.D. P values of significance (**<0.01, ***<0.001) were determined using the t-test with Welch’s corrections. NS-Not significant.
