Melanogenesis in Cryptococcus neoformans [PDF]
Microbiology, 1988 Melanogenesis in Cryptococcus neoformans begins with the oxidation of dihydroxyphenylalanine by the enzyme phenol oxidase. The succeeding steps are very rapid. Two intermediates, dopachrome and 5,6-dihydroxyindole, have been isolated and characterized by high performance liquid chromatography. A pathway of melanin formation in C. neoformans is proposed,

Galactoxylomannans of Cryptococcus neoformans [PDF]
Infection and Immunity, 1992 Galactoxylomannans (GalXMs) from single isolates of Cryptococcus neoformans serotypes A, B, and D were isolated from culture supernatants and then purified by affinity, ion-exchange, and gel-filtration chromatography. GalXMs are a group of closely related complex polysaccharides.

The capsule ofCryptococcus neoformans [PDF]
Virulence, 2018 The capsule of Cryptococcus neoformans is its dominant virulence factor and plays a key role in the biology of this fungus. In this essay, we focus on the capsule as a cellular structure and note the limitations inherent in the current methodologies available for its study.

Ultrastructure of Cryptococcus neoformans
Acta Dermato-Venereologica, 1982 The ultrastructure of C. neoformans was studied in two cases of cutaneous cryptococcosis. Extracellular and intracellular fungi were observed. Their capsules and clear zones were thick and distinct, but their cytoplasmic organelles were not obvious. In macrophages, a few stages of fungal degeneration could be observed.

Revista do Instituto de Medicina Tropical de São Paulo, 1994 El aislamiento de Cryptococcus neoformans var. gattii, serotipo B, a partir del medio ambiente se estableció inicialmente en Australia en 1989, en asocio con el Eucalyptus camaldulensis y posteriormente con E. tereticornis. Con estos hallazgos se postuló

Visible DNA microarray and loop-mediated isothermal amplification (LAMP) for the identification of Cryptococcus species recovered from culture medium and cerebrospinal fluid of patients with meningitis [PDF]
Brazilian Journal of Medical and Biological Research, 2020 Cryptococcal meningitis affects normal hosts and immunocompromised patients exhibiting high mortality rates. The objective of this study was to design two molecular assays, visible microarray platforms and loop-mediated isothermal amplification (LAMP ...
