C. albicans exhibits a wide range of morphological phenotypes due to phenotypic switching and bud to hypha transition. The yeast-to-hyphae transition (filamentation) is a rapid process and induced by environmental factors. Phenotypic switching is spontaneous, happens at lower rates and in certain strains up to seven different phenotypes are known.
Sporothrix schenckii can be found in one of two morphologies, hyphal or yeast. The hyphal form is found in the environment on plants and decaying matter. When the fungus makes the transition into a host, the yeast morphology predominates.
Candida albicans growing as yeast cells and filamentous (hypha) cells. A dimorphic fungus is a fungus that can exist in the form of both mold [1] and yeast.As this is usually brought about by a change in temperature, this fungus type is also described as a thermally dimorphic fungus. [2]
The white material is made up of debris, fibrin, and desquamated epithelium that has been invaded by yeast cells and hyphae that invade to the depth of the stratum spinosum. [4] As an erythematous surface is revealed beneath the pseudomembranes, some consider pseudomembranous candidiasis and erythematous candidiasis stages of the same entity. [4]
A blastoconidium (plural blastoconidia) is an asexual holoblastic conidia formed through the blowing out or budding process of a yeast cell, which is a type of asexual reproduction that results in a bud arising from a parent cell. [1] [2] The production of a blastoconidium can occur along a true hyphae, pseudohyphae, or a singular yeast cell. [3]
C. tropicalis is virulent due to its ability to produce biofilm, secrete lytic enzymes, adhere to epithelial and endothelial cells, and undergo transition of bud to hyphae. [ 18 ] [ 11 ] [ 7 ] Biofilms are complex structures that are formed from the grouping of microorganisms on a local surface, either biotic or abiotic, [ 18 ] dependent on the ...
A hypha (from Ancient Greek ὑφή (huphḗ) 'web'; pl.: hyphae) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. [1]
All teleomorph forms appear to be parasites of other fungi. In teleomorphs the hyphae are colourless, are clamped or unclamped, and bear haustorial cells with filaments that attach to the hyphae of host fungi. [7] [8] The basidia are club-shaped and highly elongated. Spores arise in succession from four loci at the apex (which is sometimes ...
