Jan 24, 2019 · Because Cryptococcus neoformans can be found in many parts of the environment, it is very difficult to prevent coming into contact with it. Moreover, the fungus can live in a person’s body for many months or possibly years before it causes disease, depending on the health of the person’s immune system. Cryptococcus neoformans pneumonia and infection outside the central nervous system in immunocompetent and immunocompromised patients will be reviewed here. The microbiology and epidemiology of C. neoformans infection are presented separately. Cryptococcus neoformans is a fungus that lives in the environment throughout the world.

Cryptococcus neoformans and Cryptococcus gattii are the main pathogenic species of invasive cryptococcosis among the Cryptococcus species. Taxonomic studies have shown that these two taxa have different genotypes or molecular

They belong to the phylum Basidiomycota and can be readily distinguished from other pathogenic yeasts such as Candida by the presence of a polysaccharide capsule, formation of melanin, and urease activity, which all function as virulence determinants. C. uniguttulatus (Filobasidium uniguttulatus is a teleomorph) was the first non- neoformans Cryptococcus to infect a human. It was isolated from ventricular fluid from a patient having had a neurosurgical procedure. This species was found to be very sensitive to amphotericin B … The fungi Cryptococcus neoformans is a yeast-like growth that releases infectious spores into the air. It can be present in decomposing plant or animal material but is most often found in pigeon droppings. The spores cause severe upper respiratory and nasal problems in affected cats. Only a small number of exposed cats develop infection.
