Start studying fungi: sketchymicro + pictures learn vocabulary, terms, and more with flashcards, games, and other study tools cryptococcus neoformans . Cryptococcus neoformans – a basidomycetous fungus that has two distinct varieties (c neoformans var grubii, formerly type a and c neoformans var neoformans, formerly type d) cryptococcus gattii (formerly c neoformans types b and c) is considered a separate species what is the best treatment .
Cryptococcus gattii – 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, cryptococcus gattii causes the human diseases of pulmonary cryptococcosis, basal meningitis, and cerebral cryptococcomas. Cryptococcus neoformans is a yeast fungus that can be visualized with an india ink stain due to its thick capsule (which prevents the fungi itself from being stained) mucicarmine can also be used to stain the capsule of the fungi red. Cryptococcus neoformans is an encapsulated fungal organism that can cause disease in apparently immunocompetent, as well as immunocompromised, hosts (1,2) most susceptible to infection are patients with t-cell deficiencies ( 1 , 2 ). Cryptococcus (greek for hidden sphere) is a genus of fungi, which grow in culture as yeasts the sexual forms or teleomorphs of cryptococcus species are filamentous fungi in the genus filobasidiella the name cryptococcus is used when referring to the yeast states of the fungi. Cryptococcus gattii infection differs from cryptococcus neoformans infection in that the organism has a greater propensity toward the development of intracerebral and intrapulmonary cryptococcomas, and, in general, it responds more slowly to antifungal therapy.
Description cryptococcus neoformans is a spherical, encapsulated, non-myceliated, non-fermenting fungal cell among pathogenic fungi, c neoformans is unique in that it possesses a mucinous capsule. Cryptococcus gattii has emerged as an important fungal pathogen infection manifests most often as potentially fatal meningoencephalitis and/or pulmonary disease the emergence of clusters of cryptococcosis due to c gattii in british columbia, canada in 1999, with subsequent spread to the united states pacific northwest, challenged our understanding of this disease [ 1,2 ]. Cryptococcosis is an invasive fungal infection caused by cryptococcus neoformans or c gattii c neoformans has been isolated from several sites in nature, particularly weathered pigeon droppings.

Cryptococcus neoformans is an encapsulated yeast and an obligate aerobe that can live in both plants and animals its teleomorph is filobasidiella neoformans , a filamentous fungus belonging to the class tremellomycetes . Cryptococcus neoformans yeast cells identification: c neoformans capsule is composed of a backbone of mannose substituted with xylose and glucuronic acid, referred to as glucuronoxylomannan, much like many bacterial pathogens.
