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.
Most infections with C. neoformans occur in the lungs, as the fungus enters its host through the respiratory route. [14] Because it is normally a harmless soil fungus, C. neoformans must first adapt to its new environment inside the human body, making several virulent transformations, including the formation of a polysaccharide capsule.
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 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 ...
During the COVID-19 pandemic some fungal infections have been associated with COVID-19. [10] [23] [24] Fungal infections can mimic COVID-19, occur at the same time as COVID-19 and more serious fungal infections can complicate COVID-19. [10] A fungal infection may occur after antibiotics for a bacterial infection which has occurred following ...
Dec. 10—ROCHESTER — Cris Ross, Mayo Clinic's high-profile information technology chief who managed the $1.5 billion Epic System medical records transition, retired in November. Ross had served ...
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]
Yet, there is an increasing incidence of infections caused by C. glabrata and C. rugosa, which could be because they are frequently less susceptible to the currently used azole-group of antifungals. [25] Other medically important species include C. parapsilosis, C. tropicalis, C. dubliniensis. [8] and the more recently emerging pathogen C ...
