This research examined the expression patterns of 94 stress-related genes in seven maize inbred lines with differential expressions of resistance to aflatoxin contamination. The objective was to develop a set of genes/probes associated with resistance to A. flavus and/or aflatoxin contamination. Ninety four genes were selected from previous gene expression studies with abiotic stress to test th...

Plants are unique sources of useful metabolites. Plant essential oils display a wide range of antimicrobial effects against various pathogens. Here, we studied the essential oil from the seeds of Carum copticum. We monitored aflatoxin by high-performance liquid chromatography. Results show that Carum copticum essential oil inhibits Asergillus parasiticus growth and prevents aflatoxin production...

Aflatoxin resulting from the consumption of contaminated cereals has always been a concern in Kenya. The purpose this study was to determine economic costs aflatoxin contamination Meru and Tharaka Nithi counties A multi-stage cluster sampling using Kenya National Bureau Statistics (KNBS) design used select clusters households. Once were identified, households selected each stratified random met...

in this survey aflatoxin contamination of fifty two samples of raw milk and nine samples of commercial milk were determined by t.l.c. method. the results showed that 92.31% of the samples of raw milk and all the samples of commercial milk were contaminated by aflatoxin m1 and m2. none of the samples contained alatoxin b1, b2, g1 and g2. the maximum amounts of 23/. g/lit and 20.1 g/lit were foun...

Aflatoxin contamination of food and feed have gained global significance due to its deleterious effect on human and animal health and its importance in the international trade. The potential of aflatoxin as a carcinogen, mutagen, teratogen, and immunosuppressive agent is well documented. The problem of aflatoxin contamination of food and feed has led to the enactment of various legislation. How...

Aflatoxins are produced by the fungi Aspergillus flavus and Aspergillus parasiticus and are common food contaminants in tropical developing countries. Extensive aflatoxin consumption has been shown to be highly associated with liver disease. A case-control study was conducted to determine the association between aflatoxin and liver disease in Kumasi, Ghana. A questionnaire was administered to e...

Introduction: There are a lot of fungi in our environment which grow and reproduce if the heat and humidity are suitable. Aspergillus flavus and parasilicus are among the most important food contaminants and have major roles in food poisoning. These fungi secrete poisons which contaminate feedstuffs as well as the milk we get from the animals fed with them. Because of the dire effects of thes...

background there are different types of aflatoxins, including aflatoxin m1, m2, g1, g2, b1 and b2 produced in the food chain, especially when the food is infected with fungi and can directly be consumed by humans. considering that our country is located in the subtropical geographic region where temperature and humidity ecological factors are among determining factors in contamination with afm1...

Aspergillus flavus is a diverse assemblage of strains that include aflatoxin-producing and non-toxigenic strains with cosmopolitan distribution. The most promising strategy currently being used to reduce preharvest contamination of crops with aflatoxin is to introduce non-aflatoxin (biocontrol) A. flavus into the crop environment. Whether or not introduction of biocontrol strains into agricultu...

In order to study the contamination of Aspergillus flavus and aflatoxin production in pistachio cultivars in the Semnan province, eight cultivars of pistachio were collected from major pistachio growing areas. Using the serial dilution method, ground pistachio kernels were inoculated on plates containing AFPA medium and incubated at 28° C. This experiment was performed using three replications ...
