BACKGROUND New fungal species that are morphologically similar to Aspergillus fumigatus were recently described and included in section Fumigati. Misidentification of such fungal species, particularly of the human pathogens, Aspergillus lentulus, Neosartorya fischeri, Neosartorya hiratsukae, Neosartorya pseudofischeri and Neosartorya udagawae, has been(More)
Microsatellites (or short tandem repeats, STRs) are the genetic markers of choice for studying Aspergillus fumigatus molecular epidemiology due to its reproducibility and high discrimination power. However, the specificity of these markers must be investigated in a group of isolates from closely related species. The aim of this work was to test a(More)
Multilocus sequence typing (MLST) represents the gold standard genotyping method in studies concerning microbial population structure, being particularly helpful in the detection of clonal relatedness. However, its applicability on large-scale genotyping is limited due to the high cost and time spent on the task. The selection of the most informative(More)
The characterization, analysis and validation of evidence that concludes the description of an intentional act of biocrime or bioterrorism represent the main target of microbial forensics. But, even nowadays with the most recent technical advances, it remains extremely difficult, labour-demanding and time consuming to investigate and confirm the origin of(More)
OBJECTIVE Early diagnosis of invasive aspergillosis is essential for positive patient outcome. Likewise genotyping of fungal isolates is desirable for outbreak control in clinical setting. We designed a molecular assay that combines detection, identification, and genotyping of Aspergillus fumigatus in a single reaction. METHODS To this aim we combined 20(More)
The Structural Economic Dynamic approach is distinguished by its simultaneous approach to demand and supply sides of economic growth. However, the idea that growth itself can transform an economy, which became known in the literature as cumulative causation, cannot be properly studied by this framework because technological progress is treated in the same(More)
Practical schemes based on single nucleotide polymorphisms (SNP) have been proposed as alternatives to simplify and replace the molecular methodologies based on the extensive sequencing analysis of genes. SNaPshot mini-sequencing has been progressively experienced during the last decade and represents a fast and robust strategy to analyze critical(More)
