dimorphic fungi definition
MICROBIOLOGY NOTES DIMORPHIC FUNGIDimorphic fungi are those fungi that can exist in two different morphological forms under two different environmental conditions. These fungi exist as moulds in their natural habitat and in vitro at room temperature and as yeasts in vivo or in vitro at 37oC.hese fungi exist as moulds in their natural habitat and in vitro at room temperature and as yeasts in vivo or in vitro at 37 o C. Most of the dimorphic fungi are responsible for systemic or deep mycoses. For definitive identification of the fungus, yeast-to-mould conversion should be demonstrated.
