Table 1 Vaccination parameters weight gain, larvae counts and worm burden

From: Vaccination with recombinant paramyosin against the bovine lungworm Dictyocaulus viviparus considerably reduces worm burden and larvae shedding

Animal ID Weight gain [kg] Larvae counts [LPG] * Total worm count Male worm count Female worm count

  1. SDa = arithmetic standard deviation, SDg = geometric standard deviation, n.a. = not available.
  2. *Values represent the sum of fecal larvae counts from day 84 to 97.
  3. **SDg is a multiplicative factor and therefore dimensionless.
  4. ***Percent reduction based on arithmetic mean with values in brackets representing percent reduction based on geometric mean.
