  1. Emax is â–³logCFU24 h in the control sample (drug-free); E0 is â–³logCFU24 hrs in the experimental sample comprising ENR when the maximum potential against bacterial growth was obtained; EC50 represents the PK-PD index for the drug which shows 50% of the highest antibacterial effect; N represents Hill coefficient (demonstrating the steepness of the effect curve obtained from PK-PD index)
