Nasal organoids (IMAGE) The University of Hong Kong Caption Nasal organoids were inoculated with SARS-CoV-2 WT and BA.5 at 0.01 MOI. Virus-infected (Nucleocapsid, NP+) cells in BA.5-infected nasal organoids were remarkably more abundant than those in WT-infected organoids (Diagram A). NP+ multi-nucleated syncytia with typical morphology were readily discernible in BA.5-infected monolayers of the nasal organoids (Diagram B).
