Differentiation of aflatoxin‐producing and non‐producing strains of Aspergillus flavus group
Aims: Three conventional methods and a multiplex PCR procedure with a set of four primers (Quadruplex‐PCR) were used to differentiate between aflatoxin‐producing and non‐producing strains of the… Expand
First molecular method for discriminating between Candida africana, Candida albicans, and Candida dubliniensis by using hwp1 gene.
The authors report here a polymerase chain reaction-based assay using a single primer pair (CR-f/CR-r), allowing discrimination between Candida africana and Candida albicans by using the hwp1 gene.… Expand

Aflatoxigenic Aspergillus flavus isolates always show, by using a multiplex PCR-system, four DNA fragments specific for aflR, nor-1, ver-1, and omt-A genes. Non-aflatoxigenic A. flavus strains give… Expand
Cryptococcus neoformans/Cryptococcus gattii Species Complex in Southern Italy: An Overview on the Environmental Diffusion of Serotypes, Genotypes and Mating-Types
Given the lack of comprehensive molecular epidemiology studies in Reggio Calabria and Messina, Italy, we decided to perform an extensive environmental sampling to describe the current molecular… Expand
Current methods for identifying clinically important cryptic Candida species.
In recent years, the taxonomy of the most important pathogenic Candida species (Candida albicans, Candida parapsilosis and Candida glabrata) has undergone profound changes due to the description of… Expand
New Insight into Molecular Phylogeny and Epidemiology of Sporothrix schenckii Species Complex Based on Calmodulin-Encoding Gene Analysis of Italian Isolates
In this study, we investigated phylogenetic relationships among Italian Sporothrix schenckii isolates, by comparing their partial calmodulin sequences. In this analysis, we used 26 environmental… Expand
Molecular Epidemiology of Candida albicans and Its Closely Related Yeasts Candida dubliniensis and Candida africana
ABSTRACT We performed a molecular study to determine the occurrence of Candida albicans, Candida africana, and Candida dubliniensis in different clinical samples. The study provides new insights into… Expand
Isolation and molecular characterization of Candida africana from Jos, Nigeria.
During a survey of the prevalence of Candida spp. in Jos, Plateau State, Nigeria, two atypical C. albicans isolates were recovered. These two yeasts were germ tube positive, chlamydospore-negative… Expand
Ribosomal DNA Sequencing and Phylogenetic Analysis of Environmental Sporothrix schenckii Strains: Comparison with Clinical Isolates
The authors reported the isolation and genetic characterization of Sporothrix schenckii strains from natural environmental samples and commercial amended and garden soils. Twenty-six isolates were… Expand
Candida africana and its closest relatives
Candida africana is a recently described opportunistic yeast pathogen that has been linked to vaginal candidiasis. This yeast was first described, in 1995, as atypical chlamydospore‐negative Candida… Expand
