title: Failure of maternally derived infectious bursal disease antibodies to serotypes 1 and 2 to protect against heterologous virus.
abstract: Chicks with maternally derived infectious bursal disease antibodies to either serotype 1 or 2 were challenged at intervals between day-old and 7 weeks of age using the homologous and the heterologous viruses. With both serotypes good protection was demonstrated against the homologous challenge, but not against the heterologous virus.
