This study was conducted to determine the frequency of sensitization to Aspergillus antigens in 27 patients with perennial rhinitis. Immediate cutaneous reactivity was observed in 7 (26%) patients. In 3 of these 7 patients, hypersensitivity was restricted to Aspergillus antigens alone. One patient had an isolated late cutaneous reaction. Hypersensitivity was observed most commonly with A. flavu...

Anidulafungin (AFG) showed high activity against 27 strains of Aspergillus flavus by use of broth microdilution and disk diffusion methods. This drug was effective in vivo in a murine model of disseminated infection with five isolates tested. AFG was able to prolong survival and reduce tissue burden of infected mice but not able to reduce galactomannan serum concentrations. The AFG serum levels...

We characterize the mating-type genes in Aspergillus flavus,Aspergillus parasiticus and Petromyces alliaceus. A single MAT1-1 or MAT1-2 gene was detected in the genomes of A. flavus and A. parasiticus, which is consistent with a potential heterothallic organization of MAT genes in these species. In contrast, the only known, functionally homothallic species in Aspergillus section Flavi, P. allia...

Antifungal activity of some newly synthesized inorganic complexes I, II, III and IV against soil fungi such as Aspergillus flavus, A.fumigatus, A. niger, A. Oryzae and A.terreus. The inhibition studies reveal the better activity of the complexes towards the growth of pathogenic fungi.

The in vitro susceptibility of 105 clinical and environmental strains of Aspergillus fumigatus and Aspergillus flavus to antifungal drugs, such as amphotericin B, azoles, and echinocandins was evaluated by the broth microdilution method proposed by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Following the EUCAST-proposed breakpoints, 20% and 25% of the clinical and ...

AIMS To evaluate the cultivable mycobiota from agricultural soils exposed to pesticides, the aflatoxigenic capacity of Aspergillus section Flavi strains and the effect of glyphosate on lag phase and growth rates of native nontoxigenic Aspergillus flavus under different water potential (MPa) conditions on soil-based medium. METHODS AND RESULTS Culturable mycobiota analysis from different agric...

Stonebrood is a disease of honey bee larvae caused by fungi from the genus Aspergillus. As very few studies have focused on the epidemiological aspects of stonebrood and diseased brood may be rapidly discarded by worker bees, it is possible that a high number of cases go undetected. Aspergillus spp. fungi are ubiquitous and associated with disease in many insects, plants, animals and man. They ...

A nontoxigenic Aspergillus flavus strain, K49, is currently being tested as a biological control agent in corn fields in the Mississippi Delta. However, little is known about the overall genetic diversity of A. flavus from year to year in corn fields and specifically in Mississippi. Our objective was to assess the genetic variability of A. flavus isolates from different seasons, inoculum source...

presently appearance of resistance to antifungal agents among aspergillus species is dramatically increasing. the objective of this study was to look at the in vitro activities of antifungal drugs against iranian clinical (from nail, bronchoalveolar lavage, paranasal sinus) isolated a. flavus strains. the susceptibility of 45 aflatoxigenic and non-aflatoxigenic aspergillus flavus strains were e...

The genus Aspergillus is one of the most important filamentous fungal genera. Aspergillus species are used in the fermentation industry, but they are also responsible of various plant and food secondary rot, with the consequence of possible accumulation of mycotoxins. The aflatoxin producing A. flavus and A. parasiticus, and ochratoxinogenic A. niger, A. ochraceus and A. carbonarius species are...
