[Isolation of immunoglobulins from the egg yolk of hens immunized with intestinal viruses].

Antibodies from the yolk of eggs of chicken immunized with enteric viruses (simian rotavirus SA 11, poliomyelitis virus type 2, and Coxsackie B2) were obtained. The time course of the emergence and amplification of antibody in the yolk was followed for several months by neutralization tests and enzyme immunoassay. The long-term persistence of a high antibody level in the yolk, the simplicity of generation of large amounts of chromatographically pure preparations, as well as specificity of chicken immunoglobulins open ways for their employment in different test systems for the detection and identification of enteric viruses.
