Emergence pattern of egg-adapted avian encephalomyelitis virus by alternating passage in chickens and embryos.
The chance of inducing complete egg-adaptation was slight in alternating passage in chickens and embryos with chicken-brain-passaged viruses of wild avian encephalomyelitis viruses: egg-adaptation was accomplished by use of an incipient egg-adapting mutant, but failed with other passaged virus.
