Aflatoxins (AF) are a major problem in broiler production and significant economic public health burdens worldwide. A commercial sodium bentonite (Na-B) adsorbent was used to prevent the effect of AF [50 µg aflatoxin B1 (AFB1)/kg feed] productivity, biochemical parameters, macroscopic microscopic liver changes, AFB1 residues. The influence Na-B (0.3%) monensin (MON, 100 mg/kg), alone or combination, investigated depth. dietary treatments were as follows: treatment (T) 1: basal diet (B); T2:...

Synthetic zeolites (NaX, NaY, NaA, and CaA) were evaluated in vitro for their ability to sorb aflatoxin (AF) B1 from an aqueous solution. Zeolite NaA (ZN) was selected be tested vivo because of its high affinity stable association with AFB1. This sorbent incorporated into diets (1%) containing 2.5 mg/kg Male broiler chicks 21 42 d age received ad libitum access respective water. When compared controls, BW gains lower (P < 0.05) broilers that fed AF diets. No differences found between the...

The aims of this work were to evaluate the mycoflora and identify species Aspergillus with potential produce ochratoxin A (OA) from different wine grape varieties Mendoza, Argentina. Likewise, capacity OA by section Nigri was studied.Fifty samples grapes obtained a winery Mendoza province, surface-disinfection method used for determination using medium dichloran 18% glycerol agar (DG18). Alternaria, Penicillium identified at level. production tested in 63 strains belonging Nigri. Alternaria...

Abstract The aim was to identify the normal mycoflora in wine grapes from Argentina and Brazil. We collected 50 samples Malbec Chardonnay varieties each country during 1997–98 harvest. Yeasts were a major component of fungal population, most frequent genera filamentous fungi isolated were: Aspergillus, Penicillium Botrytis. Other identified (in decreasing order) Phythophthora, Moniliella, Alternaria Cladosporium. From grapes, mean frequency ranged 1.3 × 104 5.4 106 CFUg-1. 48 Aspergillus...

Sodium bentonite (SB) was evaluated for its ability to reduce the deleterious effects of fumonisin B1 (FB1) and aflatoxin (AFB1) in broiler diets. It incorporated into diets (0.3%) containing 2.5 mg/kg AFB1, 200 FB1, or a combination AFB1 FB1. Aflatoxin significantly diminished body weight gain, whereas FB1 SB had no effect. Addition inhibitory dietary AFB1. Feeding alone caused significant increases relative weights most observed organs. did not alter any In combined diet (AFB1 plus FB1)...

To determine fungal genera, Aspergillus and Fusarium species aflatoxin B(1) (AFB(1)), zearalenone (ZEA), deoxynivalenol (DON), fumonisin (FB(1)) contamination from pre- postfermented corn silage produced in the most important region of Argentina where practice is developed.Sampling silos was performed manually through transects at three levels: upper, middle low sections. AFB(1) FB(1) were quantified by high-performance liquid chromatography, enzyme-linked immunosorbent assay DON gas...

Ochratoxin A (OA) is a mycotoxin detected in variety of food and feeds mostly from countries with temperate climate because the fungi that produce it, mainly Aspergillus ochraceus Penicillium verrucosum. In Argentina, there no available information about natural occurrence OA ochratoxigenic feedstuffs. The aim was to evaluate poultry, pig rabbit over 8 months. Likewise, capacity by section Nigri investigated. Mycotoxin analysis showed some months sampling, three feeds. found 38% poultry feed...

Ochratoxin A (OA) is receiving attention world-wide because of the hazard it poses to human health. The aim was test distribution OA in grape juice, pulps frozen grapes, and national imported table wine obtained from markets Rio de Janeiro, Brazil. Analytical methodology using immunoaffinity column for extraction clean-up with a final separation on reversed-phase (C18) fluorescence detection high-performance liquid chromatography showed limit 21 ng l−1. mean recovery 91% red wines 82% white...

Clay feed additives have been increasingly incorporated into animal diets to prevent aflatoxicosis. Due the nonselective nature of binding interaction, many important components could also be made unavailable because these additives. The anticoccidial monensin (MON) sequestered by clays. use sodium bentonite (Na-B) from a mine in province Mendoza, Argentina, was investigated as sequestering agent effects 100 µg/kg dietary aflatoxin B(1) (AFB(1)). In vitro studies demonstrated that above Na-B...

Abstract Since there is no available information about the natural occurrence of ochratoxin‐producing fungi and ochratoxin A (OTA) in peanut seeds Argentina, aims this work were to isolate identify Aspergillus section Nigri evaluate OTA stored seeds. Likewise, capacity produce by was studied. Forty‐seven samples obtained from a storage plant south Córdoba Province, Argentina. Each sample 100 surface‐disinfected plated onto dichloran 18% glycerol agar (DG18). detected HPLC. The production...

Considering the impact of Aspergillus species on crops, it appears to be highly desirable apply strategies prevent their growth, as well eliminate or reduce presence in food products. For this reason, aims investigation were evaluate effects ten natural phenolic compounds parasiticus growth and determine which physicochemical properties are involved antifungal activity. According results minimum inhibitory concentration (MIC) values individual compounds, isoeugenol, carvacrol, thymol most...

Agriculture is one of the bases Argentine economy. Glyphosate undoubtedly most important herbicides used. The increasing consumption and efficiency glyphosate-based have encouraged several studies on their persistence in soils, effects soil microbiota degradation processes. Fungi been reported as being main herbicide-degrading microorganisms well tolerant to environmental stress conditions. This study evaluated growth performance Aspergillus section Flavi niger aggregate strains Czapek Dox...
