  1. Data representing average cell number of CD4+, CD8+, IgM and macrophages with standard deviation from chicken bursa of Fabricius cells of five chickens from each group.
  2. Different asterisk signs show significant difference between infection time points (P ≤ 0.05).
  3. Different alphabets show significant difference between different strains of NDV (P ≤ 0.05).
