title: The effect of bursectomy on vaccination against Marek's disease with the herpesvirus of turkeys.
abstract: Protection against Marek's disease following vaccination with the herpesvirus of turkeys was significantly impaired but not abolished by ablation of the bursa-dependent lymphoid system by surgery and X-irradiation. It was concluded that the humoral immune system is relatively more important in vaccinal immunity induced by the herpesvirus of turkeys compared with that induced by attenuated Marek's disease virus.
