Yeast

Yeast are a biologically paraphyletic group of eukaryotic organisms.

Importance of yeasts in medicine
They are important for medicine for several reasons. Some yeasts can cause diseases, such as vulvovaginal candidiasis. Yeast of the genus Candida can be pathogenic, mostly as opportunistic infections. Opportunistic infections in immunocompromised patients are in practice caused only by the yeast of the genus Cryptococcus. Yeast extracts can be used as a dietary supplement or medicine, especially in the supplementation of certain B vitamins. The basis is often the yeast  Saccharomyces cerevisiae , the yeast that is the basis of yeast used for baking.

Some yeasts can be used as an inexpensive model organism in molecular biology research. In particular, the yeast Saccharomyces cerevisiae is one of the basic model organisms in molecular biology. Some yeasts can be used as an active ingredient in a bioreactor in the synthesis of some proteins.

Candidiasis (candidosis)
Candidiasis is an infection caused by a yeast of the genus Candida. There are more than 20 types of candida that can cause infections in humans. The most common pathogen is  Candida albicans . Yeast is a common component of the intestinal, mucosal and cutaneous flora. If they overgrow, problems can develop. Candidiasis of the mouth and throat is called thrush (powdery mildew, oropharyngeal candidosis). Vaginal candidiasis or yeast vulvovaginitis (vulvovaginitis candidomyceta). When yeast enters the bloodstream, invasive candidiasis develops.
