Invasive aspergillosis is a devastating disease caused by breathing in small airborne spores of the fungus Aspergillus fumigatus and it is a condition where drug resistance has been encountered.
In a healthy person these spores are destroyed by the body's immune system but in those with a weakened immune system -- such as following organ transplantation or in someone with a lung condition such as asthma or cystic fibrosis -- they can trigger a range of problems including infections.

Every year aspergillosis leads to more than 200,000 life-threatening infections and increasingly resistance to vital antifungal drug treatments makes those infections harder to treat.
National Institutes of Health (USA) funding supported a collaboration between the University of Tennessee, the University of Texas and Swansea University as part of a $2 million, five-year research programme. This support enabled investigation of resistance to the triazole class of antifungal drugs used for treating the disease
A new paper shows how researchers have been able to identify a previously uncharacterised genetic mutation in clinical isolates that leads to resistance.
