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. Most yeast species formerly referred to Cryptococcus have
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 .
Cryptococcosis is usually associated with immunosuppressed people, such as those with AIDs, corticosteroid use, diabetes, and organ transplant. [48] Cryptococcus comprizes two clinically relevant species, Cryptococcus neoformans and Cryptococcus gattii. [49]
Some species produce filamentous, sexual states with distinctive basidia and are parasites of other fungi. Most, however, are only known from their yeast states. Several species of Cryptococcus are human pathogens.
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 majority of Cryptococcus species live in the soil and do not cause disease in humans. Cryptococcus neoformans is the major human and animal pathogen. Papiliotrema laurentii and Naganishia albida, both formerly referred to Cryptococcus, have been known to occasionally cause moderate-to-severe disease in human patients with compromised immunity.
Cryptococcus consortionis is a fungus species. It produces colonies that are cream colored with a glistening, mucoid appearance. When grown in liquid media, this species requires constant agitation. This species growth range is from 4 °C to 23 °C, with growth at 23 °C occurring very slowly.
Naganishia adeliensis (synonym Cryptococcus adeliensis [1]) is a species of fungus in the family Filobasidiaceae. It is currently only known from its yeast state, isolated from decaying algae in Antarctica. When plated on agar Naganishia adeliensis produces colonies that are cream, with a smooth, glossy appearance. The colonies frequently ...
