Is there a possibility that viral propagation promoted on SPF embryonated eggs but not on non SPF ones?

Is antibody produced against fowlpox virus vertically transferred via eggs and further inhibited viral propagation on non-SPF cells?

C.A. (Kees) Kan

It is well established that laying hens do excrete (specic) antibodies (IgY) in their eggs when exposed to immune stimulating agents. SPF animals will be no exception , as SPF only covers certain specified pathogens and Fowl fox might not be one of them.
