Main Article

Figure 1

SARS-CoV-2 neutralizing antibodies found in serum samples from fallow deer in an urban deer population located in Dublin, Ireland, 2020–2022. A) Serum samples collected in November 2020 (n = 28); B) samples from November 2021 (n = 25); C) samples from February 2022 (n = 21). Serum samples were collected from wild fallow deer and screened in duplicate for SARS-CoV-2 neutralizing antibodies by using the Genscript cPass SARS-CoV-2 surrogate virus neutralization test (Genescript, https://www.genscript.com). Deer identification numbers are shown on the x axes for each year. Dotted lines indicate a cutoff of 30% neutralization. Red dots indicate serum samples that had >30% neutralization and were considered seropositive for SARS-CoV-2. Data are presented as mean percent neutralization calculated from duplicate wells from 2 independent assays.
