The ability of fungi to grow well at mammalian body temperatures is a fundamental characteristic of invasive human fungal pathogens. Cryptococcus neo Cryptococcus gattii used to be regarded as a third variety of C. neoformans. However, based on differences in biochemical, ecological, epidemiological and molecular characteristics, it is now recognized as a separate species

Cryptococcus neoformans é uma levedura encapsulada de grande importância médica, por ser o agente etiológico da criptococose. É encontrada em fontes ambientais, incluindo fezes de pombos, constitituindo-se em importante causa de morbidade e mortalidade em indivíduos imunodeprimidos em …

Cryptococcus (Greek for "hidden sphere", literally "hidden berry") 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. Cryptococcus neoformans is a rapidly growing typically round yeast (5-10µm) capable of producing polysaccharide capsules which often surround the cell. Recognition of encapsulated yeast cells in histopathological material, which are clearly visualized by mucicarmine staining, is sufficient to diagnose C. neoformans infections, even in the absence of culture data. Accumulation of sterylglucosides (SGs) altered the structural and physical properties of glucuronoxylomannan (GXM).
