Infectious bursal disease virus infection leads to changes in the gut associated-lymphoid tissue and the microbiota composition - Fig 4

<p><b>Staining of IBDV-antigen in the BF (A, B, C), CT (D, E, F), and caecum (G, I, H) of chickens at three days post vvIBDV-inoculation (Experiment 1).</b> Control = virus-free control, vvIBDV = vvIBDV-infected group. A, D, G are sections from virus-free controls, and B, E, I are from vvIBDV-infected birds. C, F, H are the summary of antigen positive cells in the BF, CT and caecum, respectively.
