Testing materials from room A in hospital pediatric hemotology ward in study of environmental and phylogenetic investigations of A. flavus outbreak linked to contaminated building materials, Denmark, 2025. A) Directed air sampling under the kicthenette with a polyethylene tube (red circle). B) V8 contact plate from the top of the coffee machine showing A. flavus colonies after 3 days’ incubation at 37°C. C) Discolored plywood (red circle) next to the drain after dismantling the cupboard. D) Tape preparation of the discolored area showing A. flavus stipes, heads, and spores.
