two novel aflatoxin-producing aspergillus species from argentinean peanuts.	two novel species from aspergillus section flavi from different species of arachis (peanuts) in argentina are described as aspergillus arachidicola sp. nov. and aspergillus minisclerotigenes sp. nov. their novel taxonomic status was determined using a polyphasic taxonomic approach with phenotypic (morphology and extrolite profiles) and molecular (beta-tubulin and calmodulin gene sequences) characters. a. minisclerotigenes resembles aspergillus flavus and aspergillus parvisclerotigenus in produci ...	2008	18319485
molecular strategy for identification in aspergillus section flavi.	aspergillus flavus is one of the most common contaminants that produces aflatoxins in foodstuffs. it is also a human allergen and a pathogen of animals and plants. aspergillus flavus is included in the aspergillus section flavi that comprises 11 closely related species producing different profiles of secondary metabolites. a six-step strategy has been developed that allows identification of nine of the 11 species. first, three real-time pcr reactions allowed us to discriminate four groups within ...	2010	20377644
fungal and mycotoxin assessment of dried edible mushroom in nigeria.	in order to determine whether dried mushrooms are a foodstuff that may be less susceptible to infection by toxigenic molds and consequently to mycotoxin contamination, 34 dried market samples were analyzed. fungal population was determined in the samples by conventional mycological techniques and molecular studies, while the spectrum of microbial metabolites including mycotoxins was analyzed by a liquid chromatography tandem mass spectrometric method covering 320 metabolites. molds such as fusar ...	2013	23454813
analysis of the contrast between natural occurrence of toxigenic aspergilli of the flavi section and aflatoxin b1 in cassava.	aflatoxin b1 (afb1) is a carcinogenic mycotoxin produced by aspergilli of the section flavi that may contaminate food, in the field or during storage. cassava represents an important staple food in sub-saharan africa. the analysis of aflatoxigenic fungi in 36 cassava samples obtained from producers in benin indicated that 40% were contaminated by aspergilli of the section flavi. upon morphological and molecular characterization of the 20 isolates, 16 belonged to aspergillus flavus, 2 to aspergil ...	2014	24290638
population structure and aflatoxin production by aspergillus sect. flavi from maize in nigeria and ghana.	aflatoxins are highly toxic carcinogens that contaminate crops worldwide. previous studies conducted in nigeria and ghana found high concentrations of aflatoxins in pre- and post-harvest maize. however, little information is available on the population structure of aspergillus sect. flavi in west africa. we determined the incidence of aspergillus sect. flavi and the level of aflatoxin contamination in 91 maize samples from farms and markets in nigeria and ghana. aspergillus spp. were recovered f ...	2014	24750813
