Fig. 1: FAMACHA© scores in the five study groups (n = 7 sheep/group) during the 16-week study period (x-axis).

The five graphs show the FAMACHA© results for the NEG, the POS, the BVAX, GEA and NEA groups. Each column shows the relative percentage of the FAMACHA© score of the seven sheep within each group per study week. Black arrows highlight the 1st (week 1), 2nd (week 4) and 3rd (week 7) vaccination with either vaccine. The red arrow indicates the timepoint of challenge with 5000 L3 H. contortus (week 10).
