  1. 1The birds (N = 39) were infected with 200 H. gallinarum-eggs, and necropsied 8 weeks p.i.
  2. 2For worm length it is the lowest or the highest average of an infrapopulation, not a single worm length.
  3. 3Average daily number of eggs per female worm (CEE/fem/35d).
  4. 4Defined as [Sex ratio = (females/(females + males) × 100].
