Three cases of Cryptococcus neoformans var. gattii infection in AIDS patients observed in Rio Grande do Sul (Brazil) are related. A brief comment on the epidemiology of cryptococcosis in Brazil is also made.
The emergence of distinct populations of Cryptococcus gattii in the temperate North American Pacific Northwest (PNW) was surprising, as this species was previously thought to be confined to tropical and semitropical regions. Beyond a new habitat niche, the dominant emergent population displayed increased virulence and caused primary pulmonary disease, as opposed to the predominantly neurologic ...
Cryptococcus gattii causes life-threatening yeast infection in the pulmonary and central nervous systems of humans and animals, and traditionally has been considered to restrict into the tropical and subtropical areas. Despite rare incidence of cryptococcosis caused by C. gattii in Korea, three strains of C. gattii isolated from cryptococcosis patients between 1993 and 2010 were identified. To ...
Mating in basidiomycetous fungi is often controlled by two unlinked, multiallelic loci encoding homeodomain transcription factors or pheromones/pheromone receptors. In contrast to this tetrapolar organization, Cryptococcus neoformans/Cryptococcus gattii have a bipolar mating system, and a single biallelic locus governs sexual reproduction. The C. neoformans MAT locus is unusually large (>100 kb...
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...
We present four patients from South Africa with meningitis caused by Cryptococcus neoformans var. gattii, serotype C. These are the first patients with human immunodeficiency virus (HIV) infection to be reported with serotype C meningitis.
BACKGROUND We present antifungal susceptibility data on environmental isolates of Cryptococcus neoformans (serotype A, n=117) and Cryptococcus gattii (serotype B, n=65) cultured from decayed wood of trunk hollows of Ficus religiosa and Syzygium cumini trees. METHODS Susceptibilities to amphotericin B, fluconazole, ketoconazole, itraconazole and voriconazole were determined by using Etest. The...
Cryptococcus gattii is a fungal pathogen that can cause life-threatening respiratory and disseminated infections in immune-competent and immune-suppressed individuals. Currently, there are no standardized vaccines against cryptococcosis in humans, underlying an urgent need for effective therapies and/or vaccines. In this study, we evaluated the efficacy of intranasal immunization with C. gattii...
‘Division of labour’ in response to host oxidative burst drives a fatal Cryptococcus gattii outbreak
Cryptococcus gattii is an emerging intracellular pathogen and the cause of the largest primary outbreak of a life-threatening fungal disease in a healthy population. Outbreak strains share a unique mitochondrial gene expression profile and an increased ability to tubularize their mitochondria within host macrophages. However, the underlying mechanism that causes this lineage of C. gattii to be ...
