THE CHICK EMBRYO - TYPES OF CULTIVATION OF HUMAN VIRUSES

 

Fertile chicken eggs, 9–11 days old, are used as a convenient cell system to grow a number of human pathogenic viruses. Their usefulness derives from the many types of different tissues found in the eggs, tissues that will support the growth of different viruses (Table 5.3). The use of chicken eggs is expensive and the use of cell culture is preferred wherever possible. The use of chicken eggs for the production of vaccine is necessarily subject to many controls. The eggs have to be free from specific pathogens and originate from healthy flocks. The processing of the fertilized eggs must be conducted under aseptic conditions in an area where no other infectious agents or cells are handled at the same time.
