Figure Lengend Snippet: ( a ) Combenefit mapped surface plot visually depicting the synergistic potential between QCX compounds and levofloxacin antibiotic against S. pneumoniae . The heat map was generated based on OD600 values after 24 h incubation across a minimum Inhibitory concentration (MIC)-guided concentration matrix, ranging from full MIC down to 1/8 MIC in two-fold serial dilutions for both agent types. Deeper blues illustrate where combinations yielded enhanced reduction beyond individual effects (synergy), while fading yellows and reds indicate no interaction between agents, ( b ) Time-kill assay data showing the growth pattern of S. pneumoniae treated with different combinations during 24 h, and ( c ) Effect of different combinations at lowest FIC i on percentage of inhibition of biofilm formation.
