  1. 1 I/T: number of infected lambs/total number of lambs.
  2. 2 Parasite burden is expressed as number of tachyzoites per mg of tissue. Me: median; Q25-Q75: lower - upper quartiles.
  3. Infected lambs = 50 (38 lambs with parasite DNA + 12 ewe lambs used for breeding that transmitted the infection in subsequent parturitions). Total number of lambs from gestations with transplacental passage of N. caninum = 51 (55 born lambs − 4 lambs which could not be analysed).
  4. ♦♦ Infected lambs= 14 (9 lambs with parasite DNA + 5 breeding ewe lambs that transmitted the infection in the subsequent lambing). Total number of lambs from gestations with transplacental passage of N. caninum= 18 (19 born lambs - 1 lamb which could not be analysed). 
  5. a,b Different letters within columns indicate statistically significant differences (< 0.05).
