VNII as the Main Cause of Cryptococcosis in Domestic Cats from Rio de Janeiro, Brazil.

Cryptococcosis is a systemic fungal disease acquired from contaminated environments with propagules of the basidiomycetous yeasts of the and species complexes. The species complex classically comprises four major molecular types (VNI, VNII, VNIII, and VNIV), and the species complex comprises another four (VGI, VGII, VGIII, and VGIV) and the newly identified molecular type VGV. These major molecular types differ in their epidemiological and ecological features, clinical presentations, and therapeutic outcomes.

Genotypic and Phenotypic Stability of Mixed Primary Isolates of and : A Comparative Analysis of Four Preservation Methods.

The choice of a suitable preservation method is critical for long-term microorganisms' viability. The strains should be preserved for long periods using reliable and reproducible methods that minimize genotypic and phenotypic variations and viability losses. The methodologies are usually designed for a better performance in isolated microorganisms.
