Figure 1: Faecal egg excretions: (A) during the initial infection in BBB and INRA 401
groups A, and (B) following primary infection (groups B) and challenge infection (groups A)
of the two breeds. Each infected animal was orally drenched with 10.000 L3 of H. contortus.
Figure 2: Mean blood eosinophilia in BBB lambs (A) and INRA 401 lambs (B) during the
initial and challenge infections in groups A, and following primary infection in groups B of
the two breeds. Eosinophilia in control groups was also evaluated during the period of the
challenge infection.
Figure 3: Cytokine mRNA transcriptions for IL-4, IL-5 and IL-13 in the abomasal fundic
mucosa (AFM: A, C, E) and total abomasal lymph node (ALN: B, D, F) in all infected and
control groups at 4 and 30 dpc. Assays were performed in duplicate samples using an external
standard and results were expressed after normalisation (ratio) with a housekeeping gene
(ovine beta-actin).
