THE PHARMACOKINETICS OF OCHRATOXIN A IN RATS

open access: yesJapanese Journal of Pharmacology, 1977
The absorption and tissue distribution of ochratoxin A (OCT A) following a single oral dose of OCT A were investigated in adult, male Wistar rats. In experiments concerning excretory patterns of OCT A, 14C-OCT A was used. A relatively large amount of OCT A was found in the circulating blood 48 hours after dosing.

Effective chemical management of Aspergillus flavus and aflatoxin contamination in pistachio nuts and orchards

open access: yesPest Management Science, EarlyView.
The study demonstrates the effectiveness of various chemical fungicides in controlling Aspergillus flavus growth and aflatoxin production in pistachios, with cyprodinil, fludioxonil, pyrimethanil and flusilazole showing the most promising results. Abstract BACKGROUND Significant presence of aflatoxins (AFs) in pistachio nuts has been reported during ...

Amplification of Polyketide Synthase gene fragments in ochratoxigenic and nonochratoxigenic black aspergilli in grapevine

open access: yesPhytopathologia Mediterranea, 2011
Members of the Aspergillus section Nigri, also known as black aspergilli produce Ochratoxin A (OTA), a contaminant of wine. Despite potentially severe health effects and economic losses caused by OTA in wine, almost nothing is known about the genetics ...

Efflux at the Blood-Brain Barrier Reduces the Cerebral Exposure to Ochratoxin A, Ochratoxin α, Citrinin and Dihydrocitrinone

open access: yesToxins, 2021
Recent studies have implied that environmental toxins, such as mycotoxins, are risk factors for neurodegenerative diseases. To act directly as neurotoxins, mycotoxins need to penetrate or affect the integrity of the blood-brain barrier, which protects ...

The Pathology and Blood Biochemistry of Juvenile Lates calcarifer on Diets Contaminated With Mycotoxins, Histamines and Rancid Fats—A Case Study

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Mycotoxins, originating from contaminated raw materials or suboptimal feed storage, are a growing concern in tropical aquaculture. Common fungi such as Aspergillus spp. and Fusarium spp. produce mycotoxins including aflatoxin, fumonisin, deoxynivalenol and zearalenone. High doses or prolonged exposure (weeks) to low doses of these mycotoxins (<

Control of Ochratoxin A Production in Grapes [PDF]

open access: yesToxins, 2012
Ochratoxin A (OTA) is a mycotoxin commonly present in cereals, grapes, coffee, spices, and cocoa. Even though the main objective of the food and feed chain processors and distributors is to avoid the extended contamination of plant-derived foods and animal feeds with mycotoxins, until now, complete OTA removal from foods and feedstuffs is not feasible.
