1 The mortality rate was calculated using Abbott's formula, due to the mortality rate in the control group was close to 10.0%. Values with the same superscript letters within a column do not show statistically significant differences by Sheffé, Tukey-Kramer and Neuman-Keuls tests (p < 0.05). The values are the mean of three assays, ± the standard deviation.
