For most of the half century that aflatoxigenic species have been intensively studied, these molds were known only to reproduce asexually, with parasexuality found only in the laboratory between certain mutant strains. Therefore, the fairly recent discovery of their sexual (teleomorphic) states creates a new wrinkle in our understanding of the field behavior of these agriculturally significant ...

To assess the incidence of aflatoxins contamination in different commodities, a representative countrywide study was conducted. One hundred composed samples of cereals, grains, spices, condiments and refined and raw sugars were analysed for aflatoxin B1, B2, G1 and G2. The moisture contents of all the food samples were also invariably determined. Only 6% of the samples namely maize and red chil...

this study was done to evaluate the effects of harvest time on some factor of ‘ahmadaqaie’ pistachio nuts in rafsanjan. in three consecutive years (2009-2012) during three stages of friut ripening (40, 70 and 100 percent of hulling), fruit was harvested and physiological and biochemical parameters were measured. the experiments were conducted as randomized complete block design with compound an...

The effects of cotton-corn rotation and glyphosate use on levels of soil-borne Aspergillus flavus, aflatoxin and fumonisin contamination in corn and cotton seed were determined during 2002-2005 in Stoneville, Mississippi (USA). There were four rotation systems (continuous cotton, continuous corn, cotton-corn and corn-cotton) for both glyphosate-resistant (GR) and non-GR cultivars-herbicide syst...

Since the early 1960s, the fungal pathogen Aspergillus flavus (Link ex Fr.) has been the focus of intensive research due to the production of carcinogenic and highly toxic secondary metabolites collectively known as aflatoxins following pre-harvest colonization of crops. Given this recurrent problem and the occurrence of a severe aflatoxin outbreak in maize (Zea mays L.), particularly in the So...

BACKGROUND Fumonisins and aflatoxins are mycotoxins that are produced by Fusarium and Aspergillus genus respectively. Due to the toxicity of aflatoxin and fumonisin and its effects on human and animals' health, the purpose of this study was analysis of total fumonisin and total aflatoxin contamination in biscuit and cookie samples in Babol City, Northern Iran. METHODS Thirty biscuit (n=15) an...

The aflatoxins are a group of chemically similar poisonous, carcinogenic fungal secondary metabolites produced by Aspergillus flavus, A. parasiticus, and A. nomius, which are abundant in warm and humid regions of the world. They are probably the most intensively researched toxins in the world due to their carcinogenic and mutagenic effects. Aflatoxins have also been identified as a potential bi...

AIMS The aims of the study were to quantify aflatoxins, the potent carcinogens associated with stunting and immune suppression, in maize and groundnut across Zambia's three agroecologies and to determine the vulnerability to aflatoxin increases after purchase. METHODS AND RESULTS Aflatoxin concentrations were determined for 334 maize and groundnut samples from 27 districts using lateral-flow ...

Thirty-six inbred lines selected in West and Central Africa for moderate to high resistance to maize ear rot under conditions of severe natural infection were screened for resistance to aflatoxin contamination using the previously established kernel screening assay. Results showed that more than half the inbreds accumulated aflatoxins at levels as low as or lower than the resistant U.S. lines G...
