ABSTRACT
The embryonated egg is a complex structure comprised of an embryo and its supporting membranes (chorioallantoic, amniotic, and yolk). The developing embryo and its membranes provide a diversity of cell types that allow for the successful replication of a wide variety of different viruses. Within the family Coronaviridae the embryonated egg has been used as a host system primarily for two avian coronaviruses within the genus Gammacoronavirus, infectious bronchitis virus (IBV) and turkey coronavirus (TCoV). IBV replicates well in the embryonated chicken egg, regardless of inoculation route; however, the allantoic route is favored as the virus replicates well in epithelium lining the chorioallantoic membrane, with high virus titers found in these membranes and associated allantoic fluids. TCoV replicates only in epithelium lining the embryo intestines and bursa of Fabricius; thus, amniotic inoculation is required for isolation and propagation of this virus. Embryonated eggs also provide a potential host system for detection, propagation, and characterization of other, novel coronaviruses.
