  • Left= an agar air plate exposed for 2 minutes after the barley had been turned. showing numerous colonies of the fungus following incubation at 26C on 2% malt agar.Right= A sputum sample taken from a maltworker after exposure showing many fungal colonies when cultured on agar. His commensal yeast flora is seen towards the right base as cream/white colonies.
