a
Cell lysates from DF1 cells infected with recombinant rLaSota/VP2, rLaSota and GLS-5, and homogenized bursa of IBDV classic strain D78, were used for AC-ELISA.
b
Neutralizing MAbs with known reactivity to epitopes on VP2 protein of IBDV.
c
Antigenic reactivity determined by AC-ELISA. The presence (+) and the absence (−) of the epitope in viruses are indicated.
d
IBDV classic strain D78.
