The airborne mycobiome and associations with mycotoxins and inflammatory markers in the Norwegian grain industry

Abstract Grain dust exposure is associated with respiratory symptoms among grain industry workers. However, the fungal assemblage that contribute to airborne grain dust has been poorly studied. We characterized the airborne fungal diversity at industrial grain- and animal feed mills, and identified...
