Cryptococcus is a yeast which classfied as eukaryote, a rounded encapsulated cells. This fungi is distributed world wide, and in nature are found mainly in soil contaminated by pigeon droppings and decaying trees. The important factors... more
Understanding of the taxonomy and phylogeny of Cryptococcus gattii has been advanced by modern molecular techniques. C. gattii probably diverged from Cryptococcus neoformans between 16 million and 160 million years ago, depending on the... more
Cryptococcus gattii-induced cryptococcosis is an emerging infectious disease of humans and animals worldwide, with rare descriptions of this infection in domestic animals from Brazil. This study presents the findings associated with C.... more

Cryptococcus neoformans is one of the medically important yeast-like fungi. C. neoformans var. gatti has been made a species: C. gatti. In our country, there are few studies about these two species and their serotypes. The aim of this... more
Thirty-seven isolates from 10 HIV-negative and 26 HIV-positive patients in Mato Grosso were evaluated. Direct examination, culturing and chemotyping of species were performed. Ketoconazole, itraconazole, voriconazole, fluconazole and... more
Compared to Cryptococcus neoformans, little is known about the virulence of the molecular types in Cryptococcus gattii. We compared in vitro virulence factor production and survival data using a Drosophila model of infection to further... more
We have developed a two-step method based on high-resolution melting (HRM) that reliably identifies species from the Cryptococcus species complex ( Cryptococcus neoformans var. grubii , Cryptococcus neoformans var. neoformans , and... more
The pathogenic species of Cryptococcus are a major cause of mortality owing to severe infections in immunocompromised as well as immunocompetent individuals. Although antifungal treatment is usually effective, many patients relapse after... more
This paper presents the case of a 75-year-old Brazilian man who developed inflammatory skin lesions with nodules and ulcerations on the right forearm after an injury caused by handling barbed-wire and Eucalyptus spp. logs.... more
Cryptococcus gattii is a basidiomycetous yeast that causes life-threatening disease in humans and animals. Within C. gattii, four molecular types are recognized (VGI to VGIV). The Australian VGII population has been in the spotlight since... more
We report the first environmental isolation from India of Cryptococcus gattii, genotype amplified fragment length polymorphism 5 (AFLP5), which is one of the rarely reported genotypes of this pathogen. It originated from decayed wood... more

ABSTRACTCryptococcus gattiiis the main pathogen of cryptococcosis in healthy patients and is treated mainly with fluconazole and amphotericin B. The combination of these drugs has been questioned because the mechanisms of action could... more
Cryptococcosis is an invasive infection caused by yeast-like fungus of the genera Cryptococcus spp. The antifungal therapy for this disease provides some toxicity and the incidence of infections caused by resistant strains increased.... more
In this study, we examined in Sardinia the brain of 555 autochthonous sheep, 50 goats, and 4 mouflons which were found affected by neurological signs. We found 6 goats and one mouflon with meningoencephalitis caused by Cryptococcus sp.... more
