Effects of QX and Mass-type IBV in different segments of the oviduct on mRNA expression of proinflammatory cytokine genes. A IL-6, B IL-1β, C IFN-γ and D IL-2. Values are shown as the mean ± SEM (n = 3) of fold change in expression. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 represent significant differences between the infection groups and the control group. DPI, days post infection; SEM, standard error of the mean
