SARS-CoV-2 Omicron BA.1 infection of ex vivo lung tissue in study of SARS-CoV-2 seropositivity in urban population of wild fallow deer, Dublin, Ireland, 2020–2022. Precision cut lung slices were collected from 2 SARS-CoV-2–seronegative deer and inoculated with SARS-CoV-2 Omicron BA.1; sections were stained by using immunohistochemistry. Control sections were stained with IgG only or mock infected. A) Deer 1; B) deer 2. Arrows in first and middle panels indicate Omicron BA.1 immunoreactivity in cells morphologically consistent with type 2 pneumocytes. Third panel indicates no immunoreactivity after staining with the IgG control. No immunoreactivity was observed in the mock-infected tissues for either animal. Scale bars indicate 60 μm.
