The mycotoxin, ochratoxin A (OTA), is thought to be responsible for Balkan endemic nephropathy. OTA accumulates in several tissues, especially in the kidneys and liver. The excretion of OTA into urine is thought to be mainly by tubular secretion, presumably via the organic anion transport system. Recently, several families of multispecific organic anion transporters have been identified: organi...

Mycotoxins food contamination represents a serious risk for consumers health. They are 12 secondary metabolites of fungi that can be present in a wide range of foodstuffs. Ochratoxin A 13 (OTA) is one of the most toxic compound and it is classified as a possible carcinogenic molecule. 14 The harmful effects of OTA on human and animal health lead to a big boost to develop and 15 optimize highly ...

Samples of blood, kidney and liver per animal were randomly selected from slaughtered pigs (n=60) and analyzed for ochratoxin A. Determination of ochratoxin A (OTA) concentration in samples of kidney and liver was performed by HPTLC after immunoaffnity column clean-up, while for plasma samples, spectrofluorometric procedure was used. Of the 60 plasma samples, 60% contained OTA in the range of 2...

Ochratoxins, and particularly ochratoxin A (OTA), are toxic fungal-derived contaminants of food and other agricultural products. Growing evidence supports the degradation of OTA by chemical, enzymatic and/or microbial means as a potential approach to remove this mycotoxin from food products. In particular, hydrolysis of OTA to ochratoxin α (OTα) and phenylalanine is the presumptive product of d...

270 samples of different types of pasta and cereal products, distributed in a nursery school canteen in Milan (Italy), were analyzed to estimate the occurrence of ochratoxin A. OTA was found in all analyzed samples (100%), 39 samples exceeded the maximum limit established by European Commission Regulation for OTA in the foodstuffs listed in the relevant category. The mean concentration of ochra...

Among the many mycotoxins, T-2 toxin, citrinin (CTN), patulin (PAT), aflatoxin B1 (AFB1) and ochratoxin A (OTA) are known to have the potential to induce dermal toxicity and/or tumorigenesis in rodent models. T-2 toxin, CTN, PAT and OTA induce apoptosis in mouse or rat skin. PAT, AFB1 and OTA have tumor initiating properties, and OTA is also a tumor promoter in mouse skin. This paper reviews th...

The mycotoxin ochratoxin A (OTA) has been linked to the genesis of several disease states in both animals and humans. It has been described as nephrotoxic, carcinogenic, teratogenic, immunotoxic, and hepatotoxic in laboratory and domestic animals, as well as being thought to be the probable causal agent in the development of nephropathies (Balkan Endemic Nephropathy, BEN and Chronic Interstitia...

Abstract The goal of this study is to identify the optimum conditions for ochratoxin A (OTA) biodegradation by supernatant Agaricus campestris strain. Plackett–Burman and Box–Behnken methods were used determine OTA degradation under various incubation conditions. method was planned through 16 varied experiments with 15 variants. three most potent variants, sucrose, yeast extract wheat bran, sel...

Background: Ochratoxin A (OTA) and Aflatoxin B1 (AFB1) are toxic secondary  metabolites produced by certain mold species. In this primarily survey, we examined the OTA and AFB1 contamination of pearl millet grains distributed in Tunisia. Methods: Twenty-five pearl millet (Pennisetum glaucum L.) samples from different regions of Tunisia were analyzed by High Performance Liquid Chromatography co...
