*Real-time reverse transcription PCR was used to test the oropharyngeal and cloacal swabs collected from 10 individuals of each poultry species inoculated with SARS-CoV-2 or MERS-CoV. We tested serum samples for antibody 14 dpc by virus neutralization assay. Three birds of each species served as noninoculated controls. CL, cloacal swab; dpc, days postchallenge; MERS-CoV, Middle East respiratory syndrome coronavirus; OP, oropharyngeal swab; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
