Which microorganisms occur as yeasts or molds and can infect the skin nail beds and scalp?Dermatophytes are fungi that require keratin for growth. These fungi can cause superficial infections of the skin, hair, and nails. Dermatophytes are spread by direct contact from other people (anthropophilic organisms), animals (zoophilic organisms), and soil (geophilic organisms), as well as indirectly from fomites.
What are yeasts give one example?Yeast are eukaryotic, single celled microorganisms relating to fungi. Examples are - Saccharomyces cerevisiae, Candida albicans, Histoplasma and Blastomyces.
What organisms contain yeast?Yeast is actually a type of fungus related to mushrooms. The type of yeast used for baking is usually Saccharomyces cerevisiae, but it is one of more than 1,000 species of yeast. Our own bodies actually have plenty of yeast species that live peacefully alongside (and inside) us!
