Aspergillus flavus is a well-known ubiquitous fungus able to contaminate both in pre- and postharvest period different feed and food commodities. During their growth, these fungi can synthesise aflatoxins, secondary metabolites highly hazardous for animal and human health. The requirement of products with low impact on the environment and on human health, able to control aflatoxin production, h...

AIM The aim of this study was to determine the antifungal activity of titanium dioxide activated by indoor light on Czapek Yeast Agar (CYA). METHODS The agar plate method was used and titania P25 (Evonik) was added to the medium in the amount of 20 g.dm(-3). The control experiments without titania were also carried out. The water activity (a(w)) of the basal media was adjusted to 0.999, 0.997...

Seven fungal species (Aspergillus niger, Aspergillus versicolor, flavus, fumigatus, Rhizomucor pusillus, Trichophyton equinum and Rhizopus oryzae) were isolated from the tannery effluent collected at a industry located Challawa industrial estate of Kano State, Nigeria. niger had highest percentage occurrence frequency 36% (31) while least 4% (5). Consequently, recorded mean tolerance indices 1....

Submicronic fungal fragments have been observed in in vitro aerosolization experiments. The occurrence of these particles has therefore been suggested to contribute to respiratory health problems observed in mold-contaminated indoor environments. However, the role of submicronic fragments in exacerbating adverse health effects has remained unclear due to limitations associated with detection me...

In view of the growing incidence and the high mortality of invasive aspergillosis and candidiasis, adequate diagnostic techniques permitting timely onset of treatment are of paramount importance. More than 90 % of all invasive fungal infections in immunocompromised individuals can be attributed to Candida and Aspergillus species. To date, standardized techniques permitting rapid, sensitive and,...

Posaconazole, ravuconazole, and voriconazole are new triazole derivatives that possess potent, broad-spectrum antifungal activity. We evaluated the in vitro activity of these investigational triazoles compared with that of itraconazole and amphotericin B against 239 clinical isolates of filamentous fungi from the SENTRY Program, including Aspergillus spp. (198 isolates), Fusarium spp. (7 isolat...
