IFN-γ and IL-2 levels in peripheral blood from DTMUV-infected ducks. a IFN-γ levels of serum from the two groups of ducks infected with DTMUV. b IL-2 levels of serum from the two groups of ducks infected with DTMUV. Data were expressed as mean ± SD (n = 3). The statistical differences between both groups were evaluated by Student’s t-test. * p < 0.05, ** p < 0.01
