Ochratoxin A: The Continuing Enigma [PDF]

open access: yesCritical 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 ...

Detection and Estimation of Ochratoxin A [PDF]

open access: yesNature, 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.
