Sensitivity of recombinant and wild type (wt) viruses against antisera. (A) AOaV-1-wt virus was incubated with an antiserum against AOaV-1 for 2 h or was incubated with plain antiserum. The Vero cells were then infected with these viruses and incubated for 24 h before staining against the HN protein of AOaV-1. (B) The mock-neutralization was set to 100%, and the quantitative analysis of the virus replication was plotted for the AOaV-1 neutralized with antiserum. (C) rAOaV-1-SARS-CoV-2 virus was incubated with an anit-AOaV-1 antiserum or SARS-CoV-2 antiserum for 2 h before infection of Vero cells for another 24 h. These cells were then stained for the expression of the HN glycoprotein of rAOaV-1-SARS-CoV-2. (D) Quantitative measurement of the staining intensities plotted against the mock-treated neutralization control. *** indicates statistically significant difference with p < 0.005, and ** indicates level of significance at p < 0.05.
