Over the past two decades, several fungal outbreaks have occurred, including the high-profile 'Vancouver Island' and 'Pacific Northwest' outbreaks, caused by Cryptococcus gattii, which has affected hundreds of otherwise healthy humans and animals. Over the same time period, C. gattii was the cause of several additional case clusters at localities outside of… (More)
The present study investigates further the population structure of Candida dubliniensis and its ability to exhibit microevolution. Using 98 isolates (including 80 oral isolates) from 94 patients in 15 countries, we confirmed the existence of two distinct populations within the species C. dubliniensis, designated Cd25 group I and Cd25 group II, respectively,… (More)
Dementia and generalized myoclonic jerks were the only neurologic features in a patient with cryptococcal encephalitis. Despite the presence of numerous budding yeasts identified as Cryptococcus neoformans in the CSF, there was no inflammatory reaction. Protein and glucose levels were normal, with no pleocytosis.
The fungal meningitis pathogen Cryptococcus neoformans is a central driver of mortality in HIV/AIDS. We report a genome-scale chemical genetic data map for this pathogen that quantifies the impact of 439 small-molecule challenges on 1,448 gene knockouts. We identified chemical phenotypes for 83% of mutants screened and at least one genetic response for each… (More)
OBJECTIVES To investigate the possibilities that: (i) organ toxicity of amphotericin B-deoxycholate (AMB-DOC) is related to induction of interleukin-1beta (IL-1beta), tumour necrosis factor-alpha (TNF-alpha) and apoptosis in target organs; and (ii) the reduced toxicity resulting from the conjugation of AMB with water-soluble arabinogalactan (AMB-AG), is… (More)
