Figure 2From: Immune responses associated with homologous protection conferred by commercial vaccines for control of avian pathogenic Escherichia coli in turkeys Levels of cytokine transcripts in the spleens of vaccinated turkeys as measured by real-time qRT-PCR. Results are expressed as corrected ΔCt values ± standard error of the mean after normalization with the Ct value of 28S rRNA product of each sample. Turkey poults were given sterile saline (mock) as a coarse spray (open bars), a formalin-inactivated vaccine based on the parent strain EC34195 formulated in aluminium hydroxide adjuvant via the subcutaneous route (black bars) or Poulvac® E. coli as a coarse spray (checked black and white bars) starting at one day-old. Five birds from each group were sampled per time-point. *denotes P ≤ 0.05 relative to mock-vaccinated controls.Back to article page
