SARS-CoV-2 Neutralizing Antibodies in Free-Ranging Fallow Deer (Dama dama) and Red Deer (Cervus elaphus) in Suburban and Rural Areas in Spain

Figure 3

(a) Neutralization (cVNT) profile of SARS-CoV-2 Alpha, Delta, and Omicron BA.1 variants by antisera from fallow deer (FD) and red deer (RD) in Spain. Experiments were perfomed in duplicates for Alpha and Delta and as single replicate for Omicron variant due to limited amount of sample. Shown are reciprocal dilution for each sample and percentage of inhibition of virus. (b) Serum titers expressed as IC50 values (cVNT) and as inhibition percentage (sVNT) of seropositive FD (1,721, 1,723, 1,724, 1,727) and RD (1,736, 1,367), positive control American white-tailed deer (U.S. WTD #24), and negative controls (FD 1,722 + 1,728, RD 1,731 + 1,735). Samples under limit of detection were assigned a value of <10. (c) Bar chart of IC50 titers for each serum sample and SARS-CoV-2 variant.
