  1. Formulas for the calculation of reductions in biting ticks (NET), oviposition (EWPF) and hatch (H) are described in the “Methods” section. Efficacy (Eff) = overall efficacy compared with control = 100 [1 − (NET × EWPF × H)]. The number of rabbits immunized in each group is six (n = 6)
  2. *Significantly different vs control group (P < 0.05, Student’s t-test). #Significantly different vs Trx group (P < 0.05, Student’s t-test)
