Investigating and exploiting fungal natural products in Aspergillus spp.
… to the virulence of the human pathogen Aspergillus fumigatus. It contains a characteristic disulphide bridge responsible for the deleterious effects of this molecule. GT also displays antifungal properties, however the mechanisms of cytotoxicity behind it has not been fully …

Studies on the fungal microflora of the environment of the allergic patient
… The dominant fungi isolated were Penicillim spp. and Aspergillus spp. A size effect was demonstrated in the sistribution of spores. Lung tissue from patients suffering with respiratory disease contained many fungi, whereas the lungs of those patients dying from diseases other than respiratory …

Fungos de pré e pós colheita e a qualidade de grãos de milho
… a elevação da incidência dos fungos das espécies Aspergillus spp., Cephalosporium spp., Fusarium graminearum e Penicillium spp. A incidência de GA se elevou enquanto os grãos apresentavam umidade acima de 20%. A incidência de Fusarium moniliforme foi reduzindo à medida que os grãos perdiam água. O …

Neumonías en pacientes con cáncer: análisis epidemiológico, utilidad de los métodos diagnósticos y pronóstico
… principalmente por microorganismos específicos: Aspergillus spp., CMV, y P. jiroveci, con lo que la etiología global de este síndrome en los pacientes con cáncer no ha sido estudiada. Por último, los factores de riesgo asociados a la mortalidad por neumonía sólo se han analizado en algunos grupos …

Mid-Infrared Spectral Characterization of Aflatoxin Contamination in Peanuts
… identifications were 16% and 0%, respectively. Aspergillus species of section Flavi and the black fungi, A. niger are the most common colonists of peanuts in nature and the majority of the aflatoxin producing strains are from section Flavi. Seed colonization by selected Aspergillus spp. was …

Investigating post-harvest insect-microbe interactions and their ramifications for global food quality, human health, and insect behavior
… nine genera. Over half of the samples were from Aspergillus spp. Our data suggests that there is a more persistent risk of microbial contamination by S. oryzae than by L. serricorne. In elucidating the behavioral response of S. oryzae to microbial volatiles, two stages (sexual and asexual) of A. …

Respuestas fúngicas a señales ambientales: Funciones de las proteínas CarO, OpsA, CutA y AcyA en Fusarium fujikuroi
… wcoA. Previous data on glycerol production in Aspergillus spp. and features of the predicted CutA protein lead us to propose that F. fujikuroi produces glycerol from dihydroxyacetone, and that CutA is the enzyme involved in the synthesis of this precursor by dephosphorylation of …
