Figure Legend Snippet: Antibacterial activity of BUN against MRSA. A Chemical structure of bunamidine hydrochloride (BUN). B MIC determinations of BUN against MRSA ATCC 43300 and USA300 in MH and TSB media. C XTT assays showing concentration-dependent inhibition of metabolic activity by BUN. D Comparison of OD 630 changes over time between BUN and the bacteriostatic comparator LZD. E Time-kill kinetics demonstrating concentration-dependent bactericidal activity of BUN. F Live/dead staining of MRSA using SYTO9/PI probes after 2 h exposure to BUN. G Quantification of PI-positive (dead) cells following BUN treatment. Data are presented as mean ± SD from at least three independent experiments. Statistical analyses were performed using one-way ANOVA with post hoc comparisons; ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001
Techniques Used: Activity Assay, Concentration Assay, Inhibition, Comparison, Staining
