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.
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 .
Cryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and in the brain, where it appears as a meningitis. [4] [9] [12] Coughing, difficulty breathing, chest pain and fever are seen when the lungs are infected. [5]
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 gattii. [18] The dimorphic Basidiomycota with yeast stages and the pleiomorphic rusts are examples of fungi with anamorphs, which are the asexual ...
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.
The Cryptococcaceae are a family of fungi in the order Tremellales.The family currently contains two genera.Some species produce filamentous, sexual states with distinctive basidia and are parasites of other fungi.
Infections by other fungi, including Saccharomyces, Aspergillus (as in aspergillemia, also called invasive aspergillosiis) and Cryptococcus, are also called fungemia. It is most commonly seen in immunosuppressed or immunocompromised patients with severe neutropenia, cancer patients, or in patients with intravenous catheters.
CFW shows poor staining and fluorescence of several fungal organisms including Coccidioides immitis, Histoplasma capsulatum, and Cryptococcus neoformans. CFW staining of Pneumocystis carinii in lung biopsies can be optimized by initial CFW at room temperature for five minutes followed by 65 °C incubation for five minutes. Fluorescence may be ...
