From: Evaluation of immune protection induced by DNA vaccines from Haemaphysalis longicornis paramyosin in rabbits

Group No. of animals Total no. of ticks Total no. of biting ticks Mortality (%) Feeding time (day) Engorgement weight/female (mg) Ovipositions/female (mg) Hatchability (%) NET EWPF H Eff (%)

  1. NET = Reduction in tick numbers = Total number of biting ticks from the pcDNA3.1(+)-Pmy group / Total number of biting ticks from the control group
  2. EWPF = Reduction in weight of eggs per female = The average eggs weight of female adult from the pcDNA3.1(+)-Pmy group/ The average eggs weight of female adult from the control group
  3. H = Reduction in hatchability = Hatchability from pcDNA3.1(+)-Pmy group / Hatchability from control group
  4. Eff = Overall efficacy compared to control = 100 [1-(NET × EWPF × H)]
