Faecal egg counts (FEC) and anti-Barbervax IgG titer of individual sheep. (A) FEC from each of the 12 sheep in the trial were plotted for each available time point post challenge. The plot shows a 15-fold difference in egg excretion between vaccinated and control sheep on day 29 post challenge infection. Dots for V_1, V_3 and V_4 overlap around 0 as a result of low counts. (B) FEC measured at necropsy, plotted against respective anti-Barbervax® vaccine IgG titer, showing a negative correlation between vaccine response and egg count.
