Distribution and Quantification of Lymphocytes in the Major Lymphoid Organs of Naturally Gumboro Infected Broilers

Gumboro disease is caused by the infectious bursal disease virus (IBDV) which rapidly destroys immature B-lymphocytes of bursa of Fabricious, and causes immune suppression and high mortality in commercial broiler farms in Bangladesh. To investigate the possible effect of IBDV on lymphocytes and its...
