A photomicrograph of Candida albicans showing hyphal outgrowth and other morphological characteristics. Some species of yeast are opportunistic pathogens that can cause infection in people with compromised immune systems. Cryptococcus neoformans and Cryptococcus gattii are significant pathogens of immunocompromised people.
Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
Saccharomyces is a genus of fungi that includes many species of yeasts. Saccharomyces is from Greek σάκχαρον (sugar) and μύκης (fungus) and means sugar fungus.Many members of this genus are considered very important in food production where they are known as brewer's yeast, baker's yeast and sourdough starter among others.
Candida albicans is an opportunistic pathogenic yeast [5] that is a common member of the human gut flora.It can also survive outside the human body. [6] [7] It is detected in the gastrointestinal tract and mouth in 40–60% of healthy adults.
Cryptococcus neoformans is an encapsulated basidiomycetous yeast [1] belonging to the class Tremellomycetes and an obligate aerobe [2] that can live in both plants and animals. Its teleomorph is a filamentous fungus, formerly referred to Filobasidiella neoformans. In its yeast state, it is often found in bird excrement.
Antibiotics promote yeast (fungal) infections, including gastrointestinal (GI) Candida overgrowth and penetration of the GI mucosa. [9] While women are more susceptible to genital yeast infections, men can also be infected. Certain factors, such as prolonged antibiotic use, increase the risk for both men and women.
Accurate identification of species is important for understanding yeast ecology, something that is now possible with the increased use of DNA-based methods. Before molecular methods were available, identification was mainly based on morphology , something that resulted in misclassifications and further prevented reliable results of ecological ...
Cryptococcus is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species.The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella, while Cryptococcus was reserved for the yeasts.
