The effects of dsRNA mycoviruses on growth and murine virulence of Aspergillus fumigatus

► Clinical and environmental isolates of Aspergillus fumigatus contain mycoviruses. ► Effects of chrysovirus- and partitivirus-infection were compared in isogenic lines. ► Both viruses impact the phenotype and the growth of A. fumigatus. ► The chrysovirus did not impact the murine virulence of A. fumigatus.
