HIV/AIDS-Associated Cryptococcosis in Portugal Spanning the Pre- to Post-HAART Era: A Retrospective Assessment at the Genotypic Level Based on URA5-RFLP.

Cryptococcosis caused by the fungus Cryptococcus neoformans is an opportunistic mycosis, infecting mainly immunodepressed individuals. Molecular epidemiology studies of cryptococcosis in Europe are limited. This paper presents a retrospective study of cryptococcosis in 105 cryptococcal isolates from two hospitals in Lisbon, Portugal, among HIV/AIDS patients, from 1991 to 2007. Among these patients, the number of […]

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 […]

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.
