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 neoform
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.
It may also infect organ-transplant recipients and people receiving certain cancer treatments. [9] In its yeast state C. neoformans is found in the droppings of wild birds, often pigeons; when dust of the droppings is stirred up, it can infect humans or pets
However, there are examples of animal and human parasites where the species are dimorphic but it is the yeast-like state that is infectious. [18] 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 ...
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]
Infecting C. neoformans cells are usually phagocytosed by alveolar macrophages in the lung. [11] The invading C. neoformans cells may be killed by the release of oxidative and nitrosative molecules by these macrophages. [12] However some C. neoformans cells may survive within the macrophages. [11]
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
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]
