Trypanosoma evansi β-tubulin specific recall response with Th1 polarization in lethal challenge of rTe-β-tubulin immunized mice. a Higher rTe-β-tubulin specific (IgG) antibody titers in sera of mice immunized with rTe-β-tubulin and challenged with T. evansi blood stream forms; asterisk indicates significant difference (p ≤ 0.05) between the mean OD492 value for serum IgG in the serum of rTe-β-tubulin immunized mice compared with adjuvant and infection controls. b-f Kinetics of the serum levels of IL-4 (b), IL-5 (c), IFN-γ d and TNF-α (e) in rTe-β-tubulin or the adjuvant control immunized mice post challenge with T. evansi blood stream forms. Data presented as mean ± s.e.m. from at least 6 mice/treatment
