Abstract
Immunization with inactivated viral antigens protected chickens against Marek's disease. Nonโimmunized chickens could be protected by injections of spleen cells but not of serum from immunized, histocompatible donors. Chickens rendered agammaglobulinaemic by bursectomy and irradiation could also be immunized against Marek's disease by inoculation with viral antigens, but spleen cells from these immunized, bursectomized and irradiated donors did not confer protection on the recipients into which they were injected. It was concluded that, although in the bursectomized, immunized donors cellโmediated immunity alone was able to provide a fair degree of protection against Marek's disease, the protection afforded against the disease by spleenโcell transfer was at least partly attributable to the transfer of antibodyโproducing cells, and that humoral immunity, while not being an absolute requirement for resistance, is normally an important component of the resistance mechanism.
