Varietes and serotypes of Cryptococcus neoformans clinical isolates in Colombia.
The aim of this study was to contribute to the knowledge of the geographic distribution of Cryptococcus neoformans varieties, in Colombian patients, and to determine the mating types of such varieties. A total of 370 clinical isolates were studied. C. neoformans var. neoformans was identified in 95.2% of them. C. neoformans var. gattii in 4.8%, 4.5% being serotype B and 0.3%, serotype C. Fifty-...
متن کاملIn vitro antifungal susceptibility of clinical isolates of Cryptococcus neoformans var. neoformans and C. neoformans var. gattii.
One of the differences observed between the two varieties of Cryptococcus neoformansis the greater difficulty to achieve an adequate therapeutical response in patients affected by C. neoformans var. gattii, an observation that has been validated in vitro only rarely. The aim of this work was to study the susceptibility patterns of 35 Colombian clinical isolates of C. neoformans, 20 of which bel...
متن کاملMolecular typing and antifungal susceptibility of clinical sequential isolates of Cryptococcus neoformans from Sao Paulo State, Brazil.
The antifungal susceptibility profiles and the genetic variability of 83 sequential clinical isolates of Cryptococcus neoformans, including four Cryptococcus gattii isolates, obtained from 38 Sao Paulo AIDS patients with cryptococcal meningitis were assessed by electrophoretic karyotyping and random amplified polymorphic DNA (RAPD) analysis. The majority of the Cryptococcus neoformans isolates ...
متن کاملGlobal Molecular Epidemiology of Cryptococcus neoformans and Cryptococcus gattii: An Atlas of the Molecular Types
Cryptococcosis is a fungal disease affecting more than one million people per year worldwide. The main etiological agents of cryptococcosis are the two sibling species Cryptococcus neoformans and Cryptococcus gattii that present numerous differences in geographical distribution, ecological niches, epidemiology, pathobiology, clinical presentation and molecular characters. Genotyping of the two ...
متن کاملCryptococcus neoformans var. grubii - Pathogenicity of environmental isolates correlated to virulence factors, susceptibility to fluconazole and molecular profile.
The pathogenicity of Cryptococcus neoformans is heterogeneous and is associated with the expression of virulence factors. This study aimed to correlate the pathogenicity of C. neoformans var. grubii in BALB/c mice with in vitro virulence factors, fluconazole minimal inhibitory concentrations (MICs) and molecular profiles, before and after animal passage. Ten environmental isolates and one ATCC ...
