Brain invasion results from dissemination via either transport by free yeast cells in the bloodstream or Trojan horse transport within Cryptococcus is a single-celled, oval-shaped yeast that can cause fungal meningitis. C. neoformans is the most common species, but C. gattii has been increasing in prevalence recently in the Cryptococcus cells are spherical and may bud at any point on the surface or simultaneously at several points; a prominent feature is a mucoid polysaccharide capsule which may vary in width from very thin to several times the radius of the parent cell and buds combined. Cryptococcus neoformans is the third most common invasive fungal infection in the transplant setting following Candida and Aspergillus. Cryptococcus neoformans is known for its tropism toward the central nervous system, but kidney involvement has been reported to be as high as 50% in patients with systemic cryptococcosis.

Cryptococcus neoformans and Cryptococcus gattii are closely related basidiomycetous fungi that commonly infect humans to predominantly cause meningoencephalitis.

Cryptococcus spp. is found in bird feces (mainly C. neoformans) throughout the world, but usually the birds themselves are not infected or sick. Humans and animals usually get the infection from inhaling dust contaminated with bird feces, but humans do not transmit cryptococcosis to other humans or animals.

3 Most people who breathe in C. neoformans never get sick from it. Cryptococcus neoformans (formerly known as Torula histolytica) is an encapsulated yeast-like fungus found in dried avian (particularly pigeon) and bat excreta, and in dust contaminated with such droppings.358 From: Weedon's Skin Pathology (Third Edition), 2010 Cryptococcosis is caused by a fungus known as Cryptococcosis neoformans. The infection may be spread to humans through contact with pigeon droppings or unwashed raw fruit. Contact with an infected individual may also spread the infection.

Cryptococcosis is caused by a fungus known as Cryptococcosis neoformans. The infection may be spread to humans through contact with pigeon droppings or unwashed raw fruit. Contact with an infected individual may also spread the infection.

The dramatic increase in the incidence of Cryptococcus neoformans infections calls for an up-to-date look at its biology and pathogenesis. This volume provides a comprehensive review of the ecology, epidemiology, pathogenic mechanisms, host immunity, clinical features and diagnostic conditions, and principles of treatment and prevention of this important fungal pathogen. 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.
