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 .
It is caused by the fungi Cryptococcus neoformans or less commonly Cryptococcus gattii, and is acquired by breathing in the spores from the air. [4] These fungi are found globally in soil, decaying wood, pigeon droppings, and in the hollows of some species of trees.
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
Cancer patient Gail Armstrong, 73, died in January 2019 after she was diagnosed with cryptococcus, a fungal infection linked to pigeon droppings, in late autumn the previous year while being ...
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 .
Other pigeon related pathogens causing lung disease are Chlamydophila psittaci (which causes psittacosis), Histoplasma capsulatum (which causes histoplasmosis) and Cryptococcus neoformans, which causes cryptococcosis. Avian mites may infest domestic pigeons and cause gamasoidosis in humans. There are several methods to treat birds infested with ...
[1] [6] He also proved an association between Cryptococcus neoformans and pigeon nesting sites, after being the first to isolate the fungus from its natural habitat. [1] He provided early evidence for the effectiveness of amphotericin B in treating of systemic fungal infections. [1]
Further research conducted at the Albert Einstein College of Medicine showed that three melanin-containing fungi—Cladosporium sphaerospermum, Wangiella dermatitidis, and Cryptococcus neoformans—increased in biomass and accumulated acetate faster in an environment in which the radiation level was 500 times higher than in the normal environment.
