Average Th2-Th1 ratio. The balance between Th1 and Th2 responses was determined using the cytokine levels of each mouse, as follows: Th2/Th1 ratio = (sum of IL-4 and IL-10 levels) - (sum of IFNγ and TNF levels). Average values ± SD are presented per day. p < 0.05 (t-test) when comparing *non-infected and S. mansoni-infected mice; **non-infected and PbA-infected mice; ^†S. mansoni- and PbA-infected mice; ^‡S. mansoni- and co-infected mice; ^§PbA- and co-infected mice.
