The IFN-γ production resulting from the induced toxoplasmosis in pigs and the involvement of the different lymphocyte populations are in line with other studies, where the in vitro cytokine profile was investigated until 14 (Dawson et al., 2005), 40 (Solano Aguilar et al., 2001), or 56 dpi (Verhelst et al., 2011). Here, IFNG is linked to toxoplasmosis.
