Saccharomyces pastorianus is a yeast used industrially for the production of lager beer, and was named in honour of Louis Pasteur by the German Max Reess in 1870. [1] This yeast's complicated genome appears to be the result of hybridisation between two pure species in the Saccharomyces species complex, a factor that led to difficulty in establishing a proper taxonomy of the species.
Cryptococcus gattii, formerly known as Cryptococcus neoformans var. gattii, is an encapsulated yeast found primarily in tropical and subtropical climates. Its teleomorph is Filobasidiella bacillispora, a filamentous fungus belonging to the class Tremellomycetes.
The capsule functions as the major virulence factor in cryptococcal infection and disease. [5] Some Cryptococcus species have a huge diversity at the infraspecific level with different molecular types based on their genetic differences, mainly due to their geographical distribution, molecular characteristics, and ecological niches.

In its yeast state, it is often found in bird excrement. It has remarkable genomic plasticity and genetic variability between its strains, making treatment of the disease it causes difficult. [3] Cryptococcus neoformans causes disease primarily in immunocompromised hosts, such as HIV or cancer patients.
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.
Saccharomyces cerevisiae virus L-A, also called L-A helper virus, is a member of the Totiviridae family of viruses found primarily in Saccharomyces cerevisiae. [3] Its discovery in the 1970s was the main starting point of research on yeast virology. [ 4 ]
However, there are examples of animal and human parasites where the species are dimorphic but it is the yeast-like state that is infectious. [18] The genus Filobasidiella forms basidia on hyphae but the main infectious stage is more commonly known by the anamorphic yeast name Cryptococcus, e.g. Cryptococcus neoformans [19] and Cryptococcus ...
