Ochratoxin A (OTA) producing fungi are members of the genera Aspergillus and Penicillium. Nowadays, there are about 20 species accepted as OTA producers, which are distributed in three phylogenetically related but distinct groups of aspergilli of the subgenus Circumdati and only in two species of the subgenus Penicillium. At the moment, P. verrucosum and P. nordicum are the only OTA producing s...

Aspergillus is one of the economically most important fungal genera. Recently, the ICN adopted the single name nomenclature which has forced mycologists to choose one name for fungi (e.g. Aspergillus, Fusarium, Penicillium, etc.). Previously two proposals for the single name nomenclature in Aspergillus were presented: one attributes the name "Aspergillus" to clades comprising seven different te...

Aspergillus fungi produce mycotoxins that are detrimental to human and animal health. Two sections of aspergilli particular importance cereal food crops such as corn barley. section Flavi species like A. flavus parasiticus aflatoxins, while Circumdati ochraceus sclerotiorum ochratoxin Mitigating these toxins in feed is a critical ongoing worldwide effort. We have previously investigated biosynt...

according to the increased fungi contaminations and related damages, microbiologist's incentive in considering the fungal contaminations in human habitats had increased. some of fungi cause disease through production of toxins in animals as well as humans. since these toxins are not easily distinguishable, then it is crucial to study their characteristics. aspergillus are among the most importa...

Aspergillus, Penicillium, and Talaromyces are among the most chemically inventive of all fungi, producing a wide array of secondary metabolites (exometabolites). The three genera are holophyletic in a cladistic sense and polythetic classes in an anagenetic or functional sense, and contain 344, 354, and 88 species, respectively. New developments in classification, cladification, and nomenclature...

Occupants may complain about indoor air quality in closed spaces where the officially approved standard methods for risk assessment fail to reveal cause of problem. This study describes a rare genus not previously detected Finnish buildings, Acrostalagmus, and its species A. luteoalbus as major constituents mixed microbiota wet cork liner from an outdoor wall. Representatives were also present ...

Swine production has been associated with health risks and workers' symptoms. In Portugal, as in other countries, large-scale swine production involves several activities in the swine environment that require direct intervention, increasing workers' exposure to organic dust. This study describes an updated protocol for the assessment of occupational exposure to organic dust, to unveil an accura...
