TNF and infection: The results demonstrated that infection was able to induce an increase in the tissue levels of IFN-γ (p<0.0036) (Figure 6I) and TNF (p<0.0258) (Figure 6K) in infected mice treated with vehicle in relation to pregnant uninfected and non-pregnant uninfected mice as well as the levels of IL-6 in relation to non-pregnant uninfected mice (p<0.0006) (Figure 6J).
