Abstract:
Non neoformans cryptococci are usually regarded as saprophytes and human infections are rare. C.laurentii is rare of the non neoformans Cryptococci that can cause human infections. Incidence of human infections with Cryptococcus laurentii and albidus has increased over last couple of decades. The risk factors for C. laurentii infections usually include diminished Cell mediated immunity and presence of invasive devices, while mortality risks increases with CNS involvement and age above 45 years. Clinical manifestations are indistinguishable from other invasive yeast infections. High index of su

Abstract:
Introduction: Fungi of the genus Cryptococcus are cosmopolitan and may be agents of opportunistic mycoses in immunocompromised and sometimes immunocompetent individuals. Cryptococcus species are frequently isolated from trees and bird excreta in the environment and infection occurs by inhalation of propagules dispersed in the air. The aim was to investigate Cryptococcus species in bird excreta and tree hollows located in a university hospital area and in an academic area of a university campus.
 Methodology: A total of 40 samples of bird excreta and 41 samples of tree hollows were collect

Abstract:
Cryptococcus laurentii has been classically considered a saprophytic species, although several cases of human and animal infection have been already reported. This species is reported to be heterogenous. The taxonomy of yeast Cryptococcus laurentii was always highly ambiguous. The application of molecular biology and bioinformatic methods led to dividing of searched strains to two distinct phylogenetic groups, some varieties were recognized as species and the locution „Cryptococcus laurentii group“ was introduced. The taxonomy of this group is likely not definitive and with advancing knowledge

Both species are mainly saprofytic but Cr. laurentii is also known to be an opportunistic pathogen in immunocompromised patients.

Oilseeds and cereal grains, two major constituents of the diet of animals, contain phytic acid, which is the main storage form of phosphorus in plant cells. Monogastric animals, such as poultry and pigs, are not capable of utilising the bound phosphorus in phytic acid since they do not produce phytase, the essential hydrolysing enzyme.

Abstract:
Three yeast antagonists (two strains of Cryptococcus laurentii and one of Candida sake) from orange trees reduced incidence of green mold by 80 to 95% when tested in wounded orange fruits inoculated with Penicillium digitatum and incubated at 7ºC for 30 days. The yeasts inhibited conidial germination of the pathogen, but did not kill the spores. Effectiveness of the three yeasts as antagonists was associated in part with their ability to rapidly colonize wound sites, despite low nutrient availability. Observations suggested that production of extracellular matrix by the yeasts may have facilit
