In October and November 2004, 91 spice samples (70 ground red pepper, six black five white mix chilli samples), the majority of which originated from commercial outlets, were analysed for aflatoxins B1, B2, G1 G2 (AFB1, AFB2, AFG1, AFG2) ochratoxin A (OTA) content by high-performance liquid chromatography (HPLC) after immunoaffinity column clean-up. Eighteen 70 pepper contained AFB1, seven them in a concentration exceeding 'maximum level' 5 microg kg(-1) (range 6.1-15.7 kg(-1)). Of other...

The absorption, distribution and elimination of fumonisin B1 (and B2) after oral administration Fusarium verticillioides (MRC 826) fungal culture, mixed into the experimental feed for 10 days, was studied in weaned barrows. In order to determine absorption FB1 from marked by chromium oxide, a special T-cannula implanted distal part pigs' ileum. During feeding toxin-containing diet (45 mg kg−1) until tenth day end treatment, total quantity urine faeces collected their toxin content analysed....

The aim of this study was to evaluate the effect dietary supplementation with spirulina (Arthrospira platensis) or/and thyme (Thymus vulgaris) on total tract apparent digestibility nutrients and performance growing rabbits. At weaning (5 wk age) rabbits were randomly allotted 7 groups (42 rabbits/group, 3 rabbits/cage). Rabbits in control group (C-C) received a pelleted feed throughout experiment (5-11 without any (crude protein: 176 g CP/kg, neutral detergent fibre: 325 NDF/kg). In other...

Male Wistar rats were treated intraperitoneally (i.p.) with fumonisin B1 (FB1; 0, 20, 50 and 100 mg/kg dietary dose equivalent) for 5 10 days (n = 24–24 in each setting) to gain dose- time-dependent effects on antioxidant status oxidative stress response, clinical chemical endpoints liver, kidney lung histopathology lymphocyte damage (genotoxicity). FB1 decreased feed intake, body weight absolute liver weight, irrespective of the toxin dose. Relative increased 10-day setting. Linear response...

Fumonisins are frequent food contaminants. The high exposure to fumonisins can cause harmful effects in humans and animals. Fumonisin B1 (FB1) is the most typical member of this group; however, occurrence several other derivatives has been reported. Acylated metabolites FB1 have also described as possible contaminants, very limited data available suggest their significantly higher toxicity compared FB1. Furthermore, physicochemical toxicokinetic properties (e.g., albumin binding) acyl-FB1...

The ochratoxin A (OTA) content of urine samples from 88 healthy humans living at five settlements in three counties Hungary was determined by immunoaffinity column cleanup and high-performance liquid chromatography (HPLC). OTA detected 61% the an average concentration 0.013 ng/ml (range: 0.006-0.065 ng/ml). concentrations measured men women were not significantly different.

Mycoplasma hyopneumoniae has a primary role in the porcine respiratory disease complex (PRDC). The objective of this study was to determine whether fumonisin mycotoxins influence character and/or severity pathological processes induced lungs pigs by hyopneumoniae. Four groups ( n = 7/group) were used, one fed 20 ppm B 1 (FB ) from 16 days age (group F), only infected with M. on day 30 M), and group FB MF), along an untreated control C). Computed tomography (CT) scans (M MF) 44 demonstrated...

Abstract To test the complex, acute biochemical effects of combined, naturally co‐occurring fusariotoxins, a 5‐day rat study was performed. Mycotoxin treatment invented by intraperitoneal injection: FB 1 (F): 9 µg/animal/day (approx. 30 µg/kg bw/day), DON (D): 16.5 55 bw/day) and ZEN (Z): 12.75 42.5 bw/day). The binary groups (FB [FD], [FZ] [DZ]) as well ternary , [FDZ]) group were dosed at same combined level individual mycotoxins. Body weight, feed intake mortality not affected any...

Weaned rabbits were fed diets contaminated with 2 mg/kg diet T-2 toxin alone, or 10 fumonisin B1 (FB1) and both toxins in combination (2 + mg/kg, respectively) compared to a toxin-free control diet. Samplings performed after 4 weeks (blood liver). Bodyweight of T-2-fed group was lower weeks; the liver weight increased dramatically (threefold control). Liver total phospholipids (PLs) provided slight alterations fatty acid (FA) composition; all three toxin-treated groups showed decrease...
