摘要: Abstract Primary and secondary immune responses to Newcastle disease virus (NDV) was evaluated in chickens infected with infectious bursal (IBDV) at one 28 days of age. The geometric mean primary hemagglutination-inhibition antibody titers (GMT) IBDV day age significantly lower ( P ⩽ 0.01) than those Infection had no influence on response NDV. effect infection the cell-mediated immunity by skin allograft acceptance or survival time. There significant difference between percentage grafts accepted noninfected control chickens. However, graft time longer 0.05) group. This suggested a suppression due infection.
