Biosynthesis of Ochratoxin A [PDF]
Applied Microbiology, 1969 Biosynthesis of ochratoxin A by Aspergillus ochraceus Wilh. was investigated by radiolabeling experiments in which phenylalanine- 1 - 14 C and sodium acetate- 2 - 14 C were supplied to the fungus ...

Conversion of ochratoxin C into ochratoxin A in vivo [PDF]
Applied and Environmental Microbiology, 1984 The conversion of ochratoxin C to ochratoxin A was studied in rats after oral and intravenous administration. The concentration of ochratoxin A in the blood as a function of time was the same after oral administration of equivalent amounts of either ochratoxin C or ochratoxin A.

Ochratoxin A: The Continuing Enigma [PDF]
Critical Reviews in Toxicology, 2005 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 ...

The occurrence of ochratoxin A in coffee [PDF]
Food and Chemical Toxicology, 1995 Ochratoxin A (OA) is a nephrotoxic and nephrocarcinogenic mycotoxin which is predominantly produced by the two ubiquitous fungal genera, Aspergillus and Penicillium. OA is found in foodstuffs, predominantly in cereals but also in coffee beans. Inconsistent results have been published regarding the influence of roasting on the OA content in roasted ...

Detection and Estimation of Ochratoxin A [PDF]
Nature, 1966 THE recent isolation1 of ochratoxin A from Aspergillus ochraceus Wilh., which has a widespread natural distribution, made the development of a rapid method for the detection and estimation of the mycotoxin desirable. The following methods have been used during screening of fungal strains and media for toxin production.

Metabolism of ochratoxin A by rats [PDF]
Applied and Environmental Microbiology, 1982 Albino rats were given ochratoxin A (6.6 mg/kg body weight) intraperitoneally or per os. Independent of route administration, 6% of a given dose was excreted as the toxin, 1 to 1.5% as (4R)-4-hydroxyochratoxin A, and 25 to 27% as ochratoxin alpha in the urine.

Poultry Science, 2023 : Herein, we conducted a comparative study on the embryotoxicity of ochratoxin A (OTA) and its diastereomer 2’R-ochratoxin A (2’R-OTA) under in ovo conditions, as well as assess the in vitro embryotoxicity of these substances together with ochratoxin B ...

Toxins, 2019 Food raw materials can contain the mycotoxin ochratoxin A (OTA). Thermal processing of these materials may result in decreased OTA levels but also in the formation of the thermal isomerization product 2′R-ochratoxin A (2′R-OTA).

Toxins, 2021 Ochratoxins (OTs) are mycotoxins frequently found in wines, and their contamination can occur during any stage of the winemaking process. Ochratoxin A (OTA) has been the most widely reported and the only one whose concentrations are legislated in this ...
