Table 3 Control of H. longicornis infestation in rabbits vaccinated with rPmy

From: Evaluation on two types of paramyosin vaccines for the control of Haemaphysalis longicornis infestations in rabbits

Trial 1 Total number of ticks Number of biting ticks Feeding time (day) Engorgement weight (mg) Oviposition (mg) Hatchability (%) NET EWPF H Eff (%)
Control group (n = 6) 240 240 7.21 ± 0.06 176.37 ± 2.65 87.48 ± 1.73 86.60 ± 1.08  
Trx group (n = 6) 240 231 7.04 ± 0.07 171.67 ± 3.91 86.56 ± 2.61 85.83 ± 1.68     
rPmy group (n = 6) 240 206 6.73 ± 0.08*# 156.44 ± 3.18*# 63.33 ± 2.13*# 52.48 ± 1.89*# 0.89 0.73 0.61 60.37
  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)
