Final answer:
Signs of viral growth in inoculated eggs include cytopathic effects such as changes in cell morphology, damage to tissue membranes with lesion formation, and adverse changes to the embryo like disrupted development or death.
Step-by-step explanation:
Three signs of viral growth in inoculated eggs include:
- Cytopathic effects (CPEs) such as visual changes in cell morphology and cell lysis.
- Damage to tissue membranes including the formation of lesions or pox.
- Changes in the embryo including disrupted development or death.
When a virus is inoculated into an egg, it may replicate in locations such as the chorioallantoic membrane, the amniotic cavity, and the yolk sac, causing observable signs in these areas. The viral growth can be detected by the presence of symptoms or damage caused by the virus to the cells or structures within the egg.
