Unlike Cryptococcus neoformans, C. gattii is not particularly associated with human immunodeficiency virus infection or other forms of immunosuppression. Increased virulence may be related to its capability to rapidly proliferate within lymphocytes. [15] C. gattii infection is more likely to be limited to the lung (rather than disseminating to ...
Cryptococcus comprizes two clinically relevant species, Cryptococcus neoformans and Cryptococcus gattii. [51] C. gattii was previously thought to only be found in tropical climates and in immunocompetent persons, but recent findings of C. gattii in regions such as Canada and Western regions of North America have challenged this initial ...
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 .
lack of initial CSF pleocytosis (i.e. low CSF white blood cell count); elevated C-reactive protein; failure to sterilize the CSF before immune recovery. IRIS may be the cause of paradoxically worse outcomes for cryptococcal meningitis in immunocompetent compared with immunocompromised hosts, in whom Cryptococcus neoformans is the usual pathogen ...
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.
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 neoformans is a fungus that causes cryptococcosis, which can lead to pulmonary infection as well as nervous system infections, like meningitis. [25] [26] Histoplasma capsulatum is a species of fungus known to cause histoplasmosis, which can present with an array of symptoms, but often involves respiratory infection. [27] [28]
The taxonomy of C. gattii has been reviewed; it has now been divided into five species: C. gattii sensu stricto, C. bacillisporus, 'C. deuterogattii, C. tetragattii, and C. decagattii. [ 10 ] [ 2 ] Cryptococcus depauperatus is parasitic on Lecanicillium lecanii , an entomopathogenic fungus , and is known from Sri Lanka, England, the Netherlands ...
