Cryptococcus gattii
Research Article | Host-Microbe BiologyVariation in Cell Surface Hydrophobicity among Cryptococcus neoformans Strains Influences Interactions with AmoebasThe interaction of a microbial cell with its environment is influenced by the biophysical properties of a cell. The affinity of the cell surface for water, defined by the cell surface hydrophobicity (CSH), is a biophysical parameter that varies among different strains of Cryptococcus neoformans. The CSH influences the phagocytosis of the yeast by its natural predator...
Editor's Pick Research Article | Host-Microbe BiologyChitosan Biosynthesis and Virulence in the Human Fungal Pathogen Cryptococcus gattiiThe fungal cell wall is an essential organelle whose components provide the first line of defense against host-induced antifungal activity. Chitosan is one of the carbohydrate polymers in the cell wall that significantly affects the outcome of host-pathogen interaction. Chitosan-deficient strains are avirulent, implicating chitosan as a critical virulence factor. C. gattii...
Editor's Pick Research Article | Host-Microbe BiologyIntranasal Inoculation of Cryptococcus neoformans in Mice Produces Nasal Infection with Rapid Brain DisseminationCryptococcus neoformans causes an estimated 181, 000 deaths each year, mostly associated with untreated HIV/AIDS. C. neoformans has a ubiquitous worldwide distribution. Humans become infected from exposure to environmental sources, after which the fungus lays dormant within the human body. Upon AIDS...
Research Article | Host-Microbe BiologyA Predicted Mannoprotein Participates in Cryptococcus gattii Capsular StructureCryptococcus gattii has the ability to escape from the host’s immune system through poorly understood mechanisms and can lead to the death of healthy individuals. The role of mannoproteins in C. gattii pathogenicity is not completely understood. The present work characterized a protein, Kpr1, that...
Research Article | Therapeutics and PreventionDiscovery of a Novel Antifungal Agent in the Pathogen BoxCryptococcus neoformans and Candida albicans are two major human fungal pathogens and together account for over 1.4 million infections annually, with very high mortality rates. These fungi often infect immunocompromised individuals, such as HIV/AIDS patients. In an effort to identify novel drugs...
Perspective | Clinical Science and EpidemiologyThe Case for Adopting the “Species Complex” Nomenclature for the Etiologic Agents of Cryptococcosis
Research Article | Ecological and Evolutionary ScienceSpecies in the Cryptococcus gattii Complex Differ in Capsule and Cell Size following Growth under Capsule-Inducing ConditionsInfections with the fungal pathogen Cryptococcus gattii have been increasing in recent years. Recently, four different species have been described within C. gattii, which correspond to four previously known molecular genotypes (VGI to VGIV). Examining traits related to infection and disease is...
