2. Validation and application of an analytical method for the determination of mycotoxins in crackers by UPLC-MS/MS
Abstract An analytical method applying ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was validated for the determination of aflatoxins M2, M1, G2, G1, B2, B1, deoxynivalenol, ochratoxin A, fumonisins B1 and B2, hydrolyzed fumonisins B1 and B2, zearalenone and sterigmatocystin in crackers. The obtained recoveries (70 to 110%) a

3. Effects of mycotoxin adsorbents in aflatoxin B 1 - and fumonisin B 1 -contaminated broiler diet on performance and blood metabolite
ABSTRACT The present study examined the effect of aflatoxin (AFB1) and fumonisin (FB1) at the levels of 2 mg kg−1 AFB1 and 100 mg kg−1 FB1 and the efficiency of use of different levels of adsorbent based on sodium and calcium aluminosilicate on growth performance, hematological parameters, and biochemical parameters of broilers. A total of 1,440 Cobb bro

4. PERFORMANCE AND NUTRIENT METABOLIZABILITY IN BROILERS FED DIETS CONTAINING CORN CONTAMINATED WITH FUMONISIN B1 AND ESTERIFIED GLUCOMANNAN
ABSTRACTAn experiment was conducted to evaluate the performance and nutrient metabolizability of broilers fed diets containing fumonisin B1 (FB1) and an esterified glucomannan (EGM). In total, 420 male broilers were distributed according to a 3 x 2 + 1 factorial arrangement, corresponding to three FB1 exposure times (seven, 21, or 35 days), two dietary gluco

5. Can Ergosterol Be an Indicator of Fusarium Fungi and Mycotoxins in Cereal Products?
Presence of fungi in food and feed products is a major problem. Fungi synthesize a large number of secondary metabolites including particularly harmful mycotoxins. They can be produced in plant tissues and are commonly found all over the world in many products including cereals. A total of 44 samples were taken for identification of ergosterol - the potentia

6. Effect of fungicide on Fusarium verticillioidesmycelial morphology and fumonisin B1 production
The effect of fludioxonil + metalaxyl-M on the mycelial morphology, sporulation and fumonisin B1 production by Fusarium verticillioides 103 F was evaluated. Scanning electron microscopy analysis showed that the fungicide caused inhibition of hyphal growth and defects on hyphae morphology such as cell wall disruption, withered hyphae, and excessive septation.

7. Fusarium species and fumonisins associated with maize kernels produced in Rio Grande do Sul State for the 2008/09 and 2009/10 growing seasons
Ear rots caused by Fusarium spp. are among the main fungal diseases that contribute to poor quality and the contamination of maize grains with mycotoxins. This study aimed to determine the visual incidence of fungal-damaged kernels (FDKs), the incidence of two main Gibberella (a teleomorph of Fusarium) complexes (G. fujikuroi and G. zeae) associated with mai

8. Interação entre Lipopolissacarídeo de Salmonella Typhimurium e Fumonisina B1 em frangos de corte
Lipopolissacarídeo (LPS) é o principal componente da parede celular de bactérias Gram-negativas, sendo liberado durante a divisão celular ou morte da bactéria após lise. O LPS é um dos mais potentes ativadores do sistema imune, desencadeando uma resposta inflamatória inespecífica. A exposição ao LPS tem sido associada a uma gama de efeitos tóxico

9. Factores ambientales que afectan el contenido de fumonisina en granos de maíz
Regression logistic techniques were used to study the environmental variables associated with fumonisin content in maize grain. The dependent variable consisted of 29 values of fumonisins B1 and B2 (FB1 and FB2) from samples of susceptible hybrid sowed in several sites of the Pampas region from 2006/07 to 2008/09. Meteorological variables were recorded in re

10. Avaliação dos efeitos da fertilização nitrogenada (uréiae uréia com NBPT) e do Fungicida maxim - XL na produção de fumonisinas por Fusarium verticillioides
Corn is an economically important cereal worldwide, but it is susceptible to toxigenic fungi contamination, mainly Fusarium verticillioides. This fungus produces fumonisins, which cause several mycotoxicoses and probably esophageal cancer in humans. Due to the problems caused by F. verticillioides and fumonisin contamination in corn, during its cultivation s

11. Avaliação micológica e micotoxicológica de silagens destinadas à alimentação de bovinos de fazendas no Estado de São Paulo e Rio de Janeiro. / Mycological and mycotoxicology evaluation of silage intended to a food on cattle Farms in the State of São Paulo and Rio de Janeiro.
Despite having the second largest cattle herd in the world, the Brazilian has low rates of productivity. The performance of the animals in pastures is reasonable during the rainy season, being deficient in the dry season, caused by the low availability and quality of grass, which results in weight loss of animals. Thus ensiled foods are a recently solution t

12. Ultra-structural and histochemical analysis of channel catfish (Ictalurus punctatus) liver treated with fumonisin B1
Os efeitos histopatológicos da fumonisina B1 (FB1) foram avaliados quando a toxina foi aplicada intraperitoneal (IP) em bagre (Ictalurus punctatus). Os peixes foram divididos em 4 Grupos, sendo que os Grupos II, III e IV foram tratados com FB1 em injeções IP nas concentrações de 1; 5 e 10 mg/kg p.c./dia, respectivamente, durante 21 dias.
