Abstract
Susceptibility of turkeys, chickens and chicken embryos to SARS-CoV-2
virus was evaluated by experiment inoculation. Turkeys and chickens were
inoculated using a combination of intranasal, oral and ocular routes.
Both turkeys and chickens did not develop clinical disease or antibodies
to the virus following inoculation. Viral RNA was not detected in oral
and cloacal swabs and in tissues using quantitative real-time RT-PCR. In
addition, chicken embryos were inoculated using the yolk sac,
intravenous, chorioallantoic membrane and allantoic cavity routes did
not support replication of the virus. SARS-COV-2 virus does not affect
both turkeys and chickens in the current genetic state and does not pose
any potential risk to establish in both species of domestic poultry.
