Figure 3From: Route of infectious bronchitis virus vaccination determines the type and magnitude of immune responses in table egg laying hensRelative mRNA expression of IgA in A turbinate and B tracheal tissues, and IgY in C turbinate and D trachea tissues at 1, 3, and 5 dpv. Data are expressed as log2 mean fold change compared to the control group  ±  SEM. Expression is calculated based on double delta Ct (ΔΔCt) values. Different letters indicate significant differences (p  <  0.05) within time points, determined using one-way ANOVA.Back to article page
