Reindeer moss samples taken in 2009–2010 in northern European Russia (Murmansk oblast, Karelia) are found to be extensively
and multiply contaminated with mycotoxins. The possibility of the development on reindeer moss of individual species of toxic
fungi belonging to the genera Penicillium, Aspergillus, Alternaria, and Fusarium is discussed. 相似文献

It is established that direct solid-phase ELISA performed with the use of specific reagents allows determining the content of citrinin and ochratoxin A in poultry tissues in an amount of 4.0 and 0.8 ng/g, respectively. After broilers consumed feed contaminated with various levels of toxins for 24 h, 9–15% of the doses received were transmitted to the liver. 相似文献

OBJECTIVE: To assess a ready-to-use formulation of dicyclanil to prevent blowfly strike on Merino sheep under Australian conditions. DESIGN: Randomised clinical trials conducted in an environment house and in the field. PROCEDURE: Two environment house trials were used to measure the protection against flystrike provide by a jetting or a ready-to-use 5% spray-on formulation of dicyclanil over 22 and 31 weeks respectively. Oviposition and strikes were recorded weekly for each sheep. In two field trials the occurrence of strike in Merino sheep treated off-shears or in long wool with dicyclanil or with cyromazine was compared for up to 38 weeks after treatment. Efficacy was assessed by calculating the cumulative percentage of sheep struck. RESULTS: Under environment house conditions, sheep jetted with dicyclanil at 1.50, 0.75 and 0.30 g per sheep developed 0, 8 and 9 strikes respectively during the 22 weeks of the trial, whereas there were 358 strikes present in the placebo group. Sheep sprayed with dicyclanil at 2.25, 1.50 and 0.75 g per sheep developed 5, 11 and 29 strikes respectively between weeks 15 and 31 after treatment, whereas there were 185 strikes present in the untreated controls. In field trials the cumulative percentage of sheep struck reached 1% between weeks 12 to 13 after sheep had been treated with cyromazine. Sheep treated with dicyclanil reached the 1% limit at week 21 after treatment. CONCLUSION: Under Australian field conditions, a ready-to-use 5% spray-on formulation of dicyclanil applied off-shears or to long wool protected Merino sheep from blowfly strike for a period of at least 20 weeks. 相似文献

A highly specific enzyme immunoassay of diacetoxyscirpenol is developed on the basis of polyclonal antibodies and immobilized protein conjugate of the toxin. The possibility of using it for assessing the toxigenic potential of fungi of the genus Fusarium is shown. 相似文献
