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.
1. Morphologically fungi are unicellular (yeasts) or multicellular (hyphae). Some fungi can alternate between the two forms (dimorphic fungi). 2. Hyphae are branching, threadlike, tubular filaments that either lack cross walls (coenocytic) or have cross walls (septate). 3. Hyphae reproduce asexually via the formation of spores termed microconidia or macroconidia. 4. Fungi produce toxins such as ergot alkaloids, psychotropic agents and aflatoxins. 5. Visualization of fungi in human tissue is accomplished by treatment with 10% KOH and staining with lactophenol cotton blue,
