BACKGROUND Meningitis continues to be one of the most important infections diagnosed and treated by emergency physicians. Despite the advent of anti-infective therapy, meningitis carries a mortality rate of 20%-40%. In this study, we describe the first reported emergency medicine case of meningitis associated with Cryptococcus gattii to alert providers of this insidious, emerging global pathoge...
Cryptococcus spp. other than Cryptococcus neoformans or Cryptococcus gattii were previously considered saprophytes and thought to be non-pathogenic to humans. However, opportunistic infections associated with non-neoformans and non-gattii species, such as Cryptococcus laurentii and Cryptococcus albidus, have increased over the past four decades. We experienced a case of cryptococcosis caused by...
The pathogenic yeast Cryptococcus gattii, which is causing an outbreak in the Pacific Northwest region of North America, causes life-threatening pulmonary infections and meningoencephalitis in healthy individuals, unlike Cryptococcus neoformans, which commonly infects immunocompromised patients. In addition to a greater predilection for C. gattii to infect healthy hosts, the C. gattii genome se...
Cryptococcosis is a life-threatening infection in humans and animals caused by encapsulated yeasts of the genus Cryptococcus. Cryptococcus neoformans and Cryptococcus gattii are the main agents of this mycosis. Until 2002 C. gattii was classified as a variety of C. neoformans but now is accepted as an independent species. The laccase (phenoloxydase) enzyme produced by these yeasts is considered...
UNLABELLED Cryptococcosis is caused by the opportunistic pathogen Cryptococcus neoformans or by the primary pathogen Cryptococcus gattii. Epidemiological studies suggest that patients infected with C. gattii mainly present with pulmonary disease, while those infected with C. neoformans commonly manifest meningoencephalitis. We compared the pathogenesis of the two species using the C. neoformans...
The environmental isolation of Cryptococcus spp. is typically a difficult undertaking. Collecting samples in the field is costly in terms of travel, personnel time and materials. Furthermore, the recovery rate of Cryptococcus spp. may be very low, thereby requiring a large number of samples to be taken without any guarantee of success. Ecological niche modeling is a tool that has traditionally ...
Pulmonary infections from the environmental fungus Cryptococcus gattii (C. gattii) are notable for cryptococcomas, which are usually solitary and can be very large. As with infections with Cryptococcus neoformans (C. neoformans) patients can have concomitant cryptococcal meningitis; however, unlike for C. neoformans, infections with C. gattii often occur in immunocompetent patients. The highest...
Cryptococcosis is a potentially lethal disease of humans/animals caused by Cryptococcus neoformans and Cryptococcus gattii. Distinction between the two species is based on phenotypic and genotypic characteristics. Recently, it was proposed that C. neoformans be divided into two species and C. gattii into five species based on a phylogenetic analysis of 115 isolates. While this proposal adds to ...
