Cryptococcus
the ‘machine level’ language of life is and remains chemistry. We have to preserve our fluency in chemistry in the pursuit of our long-term dream of understanding biology and of curing disease. We need good chemical gear to avoid that the study of phenotypes remains an exercise of cartography at low-resolution. If potential targets for cures are identified, we need to remember that we cannot re...
متن کاملCryptococcus neoformans.
Seven nonencapsulated mutants of Cryptococcus neoformans were isolated from an encapsulated strain of human origin. Initially, the mutants were avirulent for mice. After several months of subculturing, six of the seven isolates reverted LO the encapsulated state and possessed varying degrees of virulence. The results of these experiments suggest that a strong correlation exists between the pres...
متن کاملExtracellular DNase activity of Cryptococcus neoformans and Cryptococcus gattii.
Extracellular DNase activity was studied in 73 strains of Cryptococcus neoformans and 12 strains of Cryptococcus gattii. DNase activity was measured by DNase agar clearance with and without Methyl Green. All strains tested showed extracellular DNase activity and no significant difference was found betweenC. neoformans and C. gattii strains. DNase production was higher in strains from clinical o...
متن کاملDiversity of the Cryptococcus neoformans-Cryptococcus gattii species complex.
More than 110 years of study of the Cryptococcus neoformans and Cryptococcus gattii species complex has resulted in an enormous accumulation of fundamental and applied biological and clinical knowledge. Recent developments in our understanding of the diversity within the species complex are presented, emphasizing the intraspecific complexity, which includes species, microspecies, hybrids, serot...
متن کاملCryptococcus neoformans and Cryptococcus gattii, the etiologic agents of cryptococcosis.
Cryptococcus neoformans and Cryptococcus gattii are the two etiologic agents of cryptococcosis. 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. Infection proceeds via inhalation and subsequent ...
