Yeast Biogeography and the Effects of Species Recognition Approaches: The Case Study of Widespread Basidiomycetous Species from Birch Forests in Russia

Understanding diversity and distribution patterns of fungi, including yeasts, ultimately depends on accuracy of species recognition. However, different approaches to yeast species recognition often result in different entities or operational taxonomic units. We studied the effects of using different yeast species recognition approaches, namely morphological species recognition (MSR) and phylogenetic species recognition (PSR), on the distribution patterns of widespread basidiomycetous yeasts.

Insights on the genotype distribution among Cryptococcus neoformans and C. gattii Portuguese clinical isolates

This study provides a comprehensive picture of the C. neoformans/C. gattii molecular types most often associated with human cryptococcosis in Portugal and assesses the impact of C. gattii in these infections. One hundred and twenty-two clinical isolates, from distinct patients, were identified as C. neoformans and genotyped by URA5-RFLP, with the molecular types VNI (45.5 %) and VNIII (30.9 %) being the most commonly found ones.
