Dimorphic fungi are organisms that have the ability to switch between two morphologies during their lifecycle: yeast and hyphae. In thermal-dimorphic fungi, morphologic changes are induced by temperature.

Novel High-Throughput Screening Method for Identification of Fungal Dimorphism Blockers. Journal of Biomolecular Screening, Vol. 20, (2) : 285-91. Stylianou

Dimorphism can be defined as the property of different fungal species to grow in the form of budding yeasts or in the form of mycelium, depending on the environmental conditions. Dimorphism may be considered as a differentiative phenomenon, similar to others exhibited by fungi: spore germination, sporulation, etc, but comparatively simple to analyze. The ability of pathogenic fungi to switch between a multicellular hyphal and unicellular yeast growth form is a tightly regulated process known as dimorphic switching. Dimorphic switching requires the fungus to sense and respond to the host environment and is essential for pathogenicity. Inhalation of spores of these dimorphic fungi causes systemic mycoses. Histoplasma capsulatum: H. capsulatum is a dimorphic fungus that exists as a mold in soil and as yeast in tissue. Dimorphic Fungal Pathogens These are fungal infections of the body caused by fungal pathogens which can overcome the physiological and cellular defences of the normal human host by changing their morphological form.

Dimorphism fungi

The term dimorphic refers to having 2 fungal shapes, typically yeasts and filamentous fungi. In most human pathogenic species that take more than one form (morphology) such as Histoplasma capsulatum, temperature is the key environmental stimulus determining the fungal cell shape.Higher temperatures (ie >35ºC) shift the fungus towards the The present invention relates to a method of identifying a dimorphism gene from a dimorphic fungus; dimorphism genes isolated from dimorphic fungi; the encoded products (proteins, peptides, RNA) which have a role in the dimorphic switch and antibodies raised against proteins or peptides encoded by dimorphism genes. It further relates to agents (drugs) useful for inhibiting the dimorphic switch Dimorphism definition, the occurrence of two forms distinct in structure, coloration, etc., among animals of the same species.

Dr. Roberts discusses the distribution and eco Histone deacetylases: revealing the molecular base of dimorphism in pathogenic fungi – – Plant pathogenic fungi need to undergo a series of morphological changes in particular phases of their infection cycle.

Dimorphism has often been deﬁned as an environmen- tally controlled ‘reversible’ process, by which certain fungi FEMS Microbiol Lett 284 (2008) 127–134 c 2008 Federation of European The yeast–hyphal dimorphism occurs to fungi belonging to different phyla and is usually stimulated by environmental factors . In fungal pathogens, including the human pathogen C. albicans and corn smut fungus U. maydis, the morphological transformation occurs during infection and is necessary for adaptation to host cells (44 ⇓ ⇓ –47). A review is presented describing the mechanism of dimorphism, subdivision into groups according to developmental stages, colonies, microscopical types, and morphogenesis of medically important dimorphic fungi (Histoplasma capsulatum, Sporotrix schenckii, Candida albicans, Wangiella dermatitidis, Exophiala verneckii, Blastomyces dermatitidis, Coccidioides immitis).
