Aspergilli as Ochratoxin Producers
Mycologia, 1972To determine whether ochratoxin is produced by species of Aspergillus other than Asp. ochraceus, 44 strains representative of the 9 spp. composing the Asp. ochraceus group were grown on both pearled wheat and cracked corn in duplicate shaken flasks at 28°C for 5 days. Rice was a poor substrate for ochratoxin production.

Ochratoxin A and Related Mycotoxins
2014Ochratoxins are toxins produced by fungal species belonging not only to Aspergilli but also to Penicillia with ochratoxin A (OTA) being the main toxin of the group followed by ochratoxin B (OTB) and ochratoxin C (OTC). These mycotoxins are formed in a variety of plant products as well as in some animal-derived products following fungal invasion.

Mycotoxins are produced by fungi, commonly known as mold. Ochratoxins are a dangereous group of mycotoxins produced as secondary metabolites by several fungi of the Aspergillus or Penicillium families. Ochratoxin have been detected in foods and beverages, including grape juice and wine.

The Lancet, 1978
Flour delivered to a school in the Bournemouth area was found by thinlayered chromatography to contain up to 6.25 mg/dg of ochratoxin. A. Penicillium cyclopium, a fungus known to produce this toxin, was found in discoloured portions of the caked flour. Ochratoxin was also found in a second sack delivered to the school, but not in samples of sound flour

Metabolic Pathways of Ochratoxin A
Current Drug Metabolism, 2011Ochratoxin A (OTA) as a carcinogenic of group 2B to humans is produced by various fungi strains as Aspergillus and Penicillium. It is one of the most common contaminant in foodstuff. OTA is nephrotoxic, hepatotoxic, teratogenic, and immunotoxic and is assumed to cause Balkan Endemic Nephropathy (BEN), a chronic kidney disease in humans when it is ...

Toxicity and metabolism of ochratoxin A
Natural Toxins, 1995AbstractThe frequent occurrence of ochratoxin A (OA) in food and feed commodities and the high incidence of human exposure, as confirmed by different surveillance studies initiated several investigations devoted to elucidating the molecular mechanisms underlying OA toxicity.

Determination of ochratoxin A in beer
Food Additives and Contaminants, 1995Because of concern about possible transmission of ochratoxin A (OA) from contaminated grain adjuncts, development of a sensitive method for its determination in beer was investigated. Solid phase extraction (SPE) on C-18 and silica gel columns in series and on an immunoaffinity column (OchraTest) were used to obtain extracts for quantitation by reverse

Interaction of citrinin and ochratoxin A
Natural Toxins, 1994AbstractThe mycotoxins citrinin and ochratoxin A are produced in common by some molds and have been found together in a number of foods and animal feeds. We used in vitro tests to determine if the Same effects are produced by these two mycotoxins when they act both independently and together.

The dialysis of Ochratoxin A (OTA)
Mycotoxin Research, 2001Standard dialysis did not result in a decrease of the OTA level in the blood serum of patients regularly treated by dialysis. Therefore, we examined the effect of dialysis on both OTA bound to the blood plasma proteins and free OTA. We carried out an in vivo experiment to determine OTA levels in the serum of patients in the terminal stage of chronic ...

The fate of ochratoxin A (OA) was studied in goats given a single oral dose of 3H-OA (0.5 mg/kg). More than 90% of the radioactivity was found to be excreted in 7 days and the majority (53%) was found in feces. Thirty-eight percent, 6% and 2.26% of the activity was found in urine, milk and serum, respectively.
