While soil application of a competitive non-toxigenic Aspergillus flavus strains is successful in reducing aflatoxin contamination in certain crops, direct application to aerial reproductive structures could be more effective for maize. A sprayable, clay-based water-dispersible granule formulation was developed to deliver non-toxigenic A. flavus strain K49 directly to maize ears. The efficacy o...

Background & Aims of the Study : Consumption of honey has remarkably increased in the last years all over the world. Factors such as plant species, environmental, processing, and storing condition are affecting honey quality. The purpose of this study was to evaluation of Hygienic quality of honey samples produced from Qazvin province. Materials and Methods: 34 fresh honey Samples were obta...

Aflatoxicosis has repeatedly affected Kenyans, particularly in the eastern region, due to consumption of contaminated maize. However, save for the cases of acute toxicity, the levels of sub-lethal exposure have not been adequately assessed. It is believed that this type of exposure does exist even during the seasons when acute toxicity does not occur. This study, therefore, was designed to asse...

Every year during the 5-year period 1976-1980, approximately 100 samples each of corn and wheat from trucks delivering the grains at elevators in Virginia were collected by personnel of the Federal Grain Inspection Service and shipped to NRRC. Samples were analyzed as soon as possible for aflatoxin, zearalenone, and ochratoxin A. The 3 mycotoxins were not detected in any wheat sample. Zearaleno...

background and purpose: mycotoxins are secondary fungal metabolites with a very high diversity that are produced by some species of aspergillus which frequently leads to contaminate food and agricultural products. recently, elimination of aflatoxin contamination in food and feed has been considered by scientists worldwide. although, the antibacterial and antifungal effects of vitamins as natura...

Background: This study intended to assess individual and combined adsorption potentials of three adsorbents (processed bentonite as an inorganic adsorbent, and cell walls of Saccharomyces cerevisiae and of the GG strain of Lactobacillus rhamnosus as organic adsorbents) for aflatoxin B1 and ochratoxin A under in vitro conditions. Methods: This study was conducted in Ferdowsi University of Mashh...

Aspergillus flavus Link:Fr. is a soilinhabiting fungus that saprophytically utilizes a wide range of organic substrates. From an agro-ecological perspective, it is an important degrader of crop debris contributing to nutrient recycling (11). A. flavus first attracted the attention of cotton researchers in the early 1950s, when it was associated with a fluorescent fiber condition of raw cotton (...

PURPOSE To document the clinical profile of patients with keratitis due to Aspergillus flavus and to elaborate on differences in the aflatoxin-producing potential of keratitis strains versus environmental strains of A. flavus. METHODS Over a 6-month period, strains of Aspergillus flavus were isolated in culture from corneal scrape or biopsy material of patients who presented with suppurative ...
