Almonds are among the commodities at risk of aflatoxin contamination by Aspergillus flavus. Temperature and water activity are the two key determinants in pre and post-harvest environments influencing both the rate of fungal spoilage and aflatoxin production. Varying the combination of these parameters can completely inhibit or fully activate the biosynthesis of aflatoxin, so it is fundamental ...

This study was conducted to investigate the effects of aflatoxin B1 (AFB1) on T-cell subsets and mRNA expression of cytokines in the small intestine of broilers. One hundred and fifty-six one-day-old healthy Cobb broilers were randomly divided into control group (0 mg/kg AFB1) and AFB1 group (0.6 mg/kg AFB1) with three replicates per group and 26 birds per replicate for 21 days, respectively. A...

conclusions antimicrobial and antitoxigenic properties of natural products need a firmly established criterion before they could be offered to application. results a significant reduction in aflatoxin production was noted which was not due to the inhibitory effect but because of antifungal property of the oil. interestingly, the oil promoted toxin production for the reasons yet to be investigat...

A sensitive electrochemical molecularly-imprinted sensor was developed for the detection of aflatoxin B1 (AFB1), by electropolymerization of p-aminothiophenol-functionalized gold nanoparticles in the presence of AFB1 as a template molecule. The extraction of the template leads to the formation of cavities that are able to specifically recognize and bind AFB1 through π-π interactions between AFB...

Organically produced spices and herbs were analyzed for determination of aflatoxin B1 (AFB1) by ELISA using immunoaffinity column. For this purpose 93 organic spices and 37 organic herbs were randomly selected from organic markets and organic shops in Turkey. AFB1 was detected in 58 organic spice and 32 organic herb samples. Among organic spice samples, the maximum value was detected in cinnamo...

The purpose of the study was to evaluate short-term effects aflatoxin B1 (AFB1 100 µg/kg feed) and sterigmatocystin (STC 1000 μg/kg exposure individually in combination (100 μg AFB1 + STC/kg on parameters lipid peroxidation glutathione redox system both biochemical gene expression levels one-year-old common carp.

Although the aflatoxins were discovered more than 30 years ago, there is still considerable controversy surrounding their human health effects. Most countries have introduced legislation to control the level of aflatoxins in food, but it is not known if these permitted levels still pose a significant cancer risk. Furthermore, it is unlikely that all the sources of human aflatoxin exposure have ...

Aflatoxin B1 (AFB1) is a highly toxic substance produced mainly by Aspergillus spp., which are known to contaminate wide variety of foods and feeds. The objective this study was understand the growth AFB1 production rate flavus NRRL 3357 investigate impact different infrared (IR) heat intensities on aflatoxin-producing potential A. flavus. Thirty healthy corn kernels were inoculated with 1 × 10...

Mycotoxin is a worldwide problem threatening animal health and performance as well public health. The objective of this experiment was to test the effect ammonization on elimination common mycotoxins in laying hen compound feed (CF) dairy cattle total mixed ration (TMR). CF for hens TMR cows were contaminated with commonly occurring [aflatoxin B1 (AFB1), ochratoxin A (OTA), zearalenone (ZEA)] a...

Antibody based techniques are widely used for the detection of aflatoxins which are potent toxins with a high rate of occurrence in many crops. We developed a murine monoclonal antibody of immunoglobulin A (IgA) isotype with a strong binding affinity to aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1), aflatoxin G2 (AFG2) and aflatoxin M1 (AFM1). The antibody was effectively used i...
