Resistant ratios RR50 and RR95 were obtained by calculating the ratio between the LD50 and LD95 between Vauclin and Bora-Bora strains; Synergism ratios SR50 and SR95 were obtained by calculating the ratio between LD50 and LD95 with and without enzyme inhibitor. (CI): Confidence Interval. Significant RR and SR are shown in bold. |
