IL-4 and IFNγ levels were also depicted in this study, showing low hepatic lymph node IFNγ levels in both the infected and immunised goats, suggesting the Th2 polarisation had occurred in the later stage of infection that is also observed in other goat vaccination trials and in cattle and sheep infections [100,101,102,103,115,116,117,118]. Here, IL4 is linked to infection.
