Tet 1 and 2 mRNAs increase after 48 hpi of IBDV within the bursa of Fabricius. A. Western blot analysis indicating that the capsid protein of IBDV, VP2, is present in both bursa and spleen of six-week old chickens infected with IBDV (48 hpi) but not in uninfected control birds. B. Relative expression of Tet 1 and Tet 2 mRNAs following IBDV infection (48 hpi) within the bursa of Fabricius. Bars are mean ± SEM. *Indicates statistical significance at the p < 0.05 level between uninfected and 48 hpi birds for the same gene as determined by unpaired t-test. n =3 birds per group.
