Cryptococcus neoformans and Cryptococcus gattii are responsible globally for almost one million cryptococcosis cases yearly, mostly in immunocompromised patients, such as those living with HIV. Infections due to C. gattii have mainly been described in tropical and subtropical regions, but its adaptation to temperate regions was crucial in the species evolution and highlighted the importance of ...
Cryptococcosis is a serious fungal infection in both huaman and animals caused by members of the Cryptococcus neoformans/ Cryptococcus gattii species complex. The main route of entry is respiratory tract. Meningitis is the most common clinical manifestation of cryptococcosis in immunocompromised patients and considered as one of AIDS defining illnesses. The known natural sources of the fungus...
Compared to the incidence in adults, cryptococcosis is rare among children. We report a case of neurocryptococcosis due to Cryptococcus gattii in a five-year-old girl without identified risk factors living in French Guiana. Neurological surgery in combination with long-term antifungal treatment with amphotericin B and 5-flucytosine successfully resolved the cryptococcal infection. Subsequent mo...
Interspecies hybrids of Cryptococcus neoformans and C. gattii have only recently been reported. We describe a novel C. neoformans x C. gattii hybrid strain (serotype AB) that was previously described as C. gattii and that caused a lethal infection in an AIDS patient from Canada.
BACKGROUND Cryptococcus gattii is a pathogenic basidiomycetous yeast that is emerging in temperate climate zones worldwide. C. gattii has repetitively been isolated from numerous tree species. Ongoing environmental sampling and molecular characterization is essential to understand the presence of this primary pathogenic microorganism in the Mediterranean environment. AIMS To report the first ...
Cryptococcus neoformans and Cryptococcus gattii are important agents of meningoencephalitis in humans in the city of Belém. This clinical data suggests that the region may be a highly endemic area for the pathogenic Cryptococcus species within the state of Pará (PA), Northern Brazil. Preliminary analysis of 11 environmental samples from the city of Belém showed two positive locations, including...
We report a case of fatal disseminated infection with Cryptococcus gattii in a patient from New Mexico. The patient had no history of recent travel to known C. gattii-endemic areas. Multilocus sequence typing revealed that the isolate belonged to the major molecular type VGIII. Virulence studies in a mouse pulmonary model of infection demonstrated that the strain was less virulent than other C....
This study presents a 7-year retrospective analysis of seasonal variations in the prevalence of Cryptococcus neoformans var. grubii and Cryptococcus gattii in decayed wood inside trunk hollows of 518 trees belonging to 20 species in north-western India during 2000-2007. Of the 1,439 wood samples investigated, 406 (28.2%) were found to be positive for the Cryptococcus neoformans species complex ...
Recent Cryptococcus gattii infections in humans and animals, including several outbreaks in goats, were the basis of this environmental survey in six provinces of Spain. A total of 479 samples from 20 tree species were studied. Cryptococcus gattii was found for the first time in autochthonous Mediterranean trees in Spain. Fourteen isolates of this pathogen were obtained from seven trees of thre...
Molecular types of the Cryptococcus neoformans/Cryptococcus gattii species complex that infect dogs and cats differ regionally and with host species. Antifungal drug susceptibility can vary with molecular type, but the susceptibility of Cryptococcus isolates from dogs and cats is largely unknown. Cryptococcus isolates from 15 dogs and 27 cats were typed using URA5 restriction fragment length po...
