Post-weaning diarrhea (PWD) is an often disease affecting piglets. It caused mainly by enterotoxigenic Escherichia coli (ETEC) colonization in pig gut. Antibiotics has been used to prevent, combat and control PWD its negative impact on the productivity of breeding sector. Nonetheless, antibiotics due their wide antibacterial spectrum also can reach beneficial gut bacteria, such as Lactobacillus. Lately, essential oils (EOs) have emerged a potential alternative using animal because effect...
Fusarium mycotoxins deoxynivalenol (DON), nivalenol (NIV) and zearalenone (ZEN) were investigated in wheat from the 2009 2010 crop years. Samples (n = 745) commercial fields collected four producing regions (WPR) which differed weather conditions. Analyses performed using HPLC-DAD. Contamination with ZEN, DON NIV occurred 56, 86 50%, respectively. Also, mean concentrations different: 1046 µg kg(-1), < 100 kg(-1) ZEN 82 kg(-1). Co-occurrence of was observed 74% samples 12% 2010. Wet/cold...
The mycotoxin deoxynivalenol (DON) contaminates animal feed worldwide, frequently resulting in poor performance and economic losses. Data concerning the effects on poultry health or focusing intestinal toxicity response to oxidative stress are scarce. Also, there is a need for strategies mitigate negative of DON. This study aimed investigate Lactobacillus spp. treatments intestine, liver kidney fed DON-contaminated diet. To achieve this aim, histological, morphometrical histochemical assays...
Deoxynivalenol (DON) is a predisposing factor for necrotic enteritis. This study aimed to investigate the effects of DON and Clostridium perfringens (CP) challenge on intestinal morphology, morphometry, oxidative stress, immune response broilers. Additionally, we evaluated potential Lactobacillus spp. mixture as an approach mitigate damage induced by challenge. One-day-old broiler chickens (n = 252) were divided into seven treatment groups: Control, DON, CP, CP + VL (DON viable mixture), HIL...
Yerba mate (Ilex paraguariensis St. Hil.) has been studied for its important biological activities mainly attributed to phenolic compounds. This study evaluated the antimicrobial activity of methanolic and ethanolic extracts yerba against food pathogens, such as Staphylococcus aureus, Listeria monocytogenes, Salmonella Enteritidis Escherichia coli through minimum inhibitory (MIC) bactericidal (MBC) concentrations, in addition determination chemical composition by gas chromatography with mass...
ABSTRACT: Essential oils are possible alternatives to the use of synthetic pesticides for control fungal contamination. Ginger (Zingiber officinale) essential oil (GEO) is known having antifungal and antiaflatoxigenic properties, but its as a fumigant in situ has not been studied yet. The aim this study was evaluate GEO’s effects upon Aspergillus flavus agent stored maize grains. main compounds reported GEO were α-zingiberene (23.85%) geranial (14.16%), characterized by gas...
Essential oils (EOs) from Citrus are the main by-product of Citrus-processing industries. In addition to food/beverage and cosmetic applications, citrus EOs could also potentially be used as an alternative antibiotics in food-producing animals. A commercial EO—Brazilian Orange Terpenes (BOT)—was fractionated by vacuum fractional distillation separate BOT into various fractions: F1, F2, F3, F4. Next, chemical composition biological activities its fractions were characterized. Results showed...
This survey evaluated the presence of AFM1 in human urine samples from a specific Brazilian population, as well corn, peanut, and milk consumption measured by two types food inquiry. Urine donors who live city Piracicaba, State São Paulo, Brazil were analyzed to detect aflatoxin M1 (AFM1), an B1 metabolite, which may be used exposure biomarker. The analysis was performed using immunoaffinity clean-up detection high-performance-liquid chromatography with fluorescence detector. A total 69 45...
Efficient detection of aflatoxins B1, B2, G1, and G2 has been performed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry using a UV-absorbing ionic liquid matrix to obtain "matrix-free" spectra addition NaCl enhance sensitivity via Na+ cationization. Using α-cyano-4-hydroxycinnamic acid (Et3N−α-CHCA) as the matrix, matrix-free in m/z range interest are acquired, readily detected with an LOD low 50 fmol. The technique is fast, requires little sample preparation...
Abstract The fungus Colletotrichum gloeosporioides , which is the causal agent of anthracnose disease in green-skinned avocados, responsible for significant postharvest fruit losses. In this context, strategies should be considered to avoid problem. use essential oil (EO) can represent an alternative contribute antifungal activity, avoiding chemical products, as their indiscriminate have harmful effects on human health. It known that may exhibit activity and used products. Therefore,...
