ЖУРНАЛ ДЛЯ ПРОФЕССИОНАЛОВ ОТ ПРОФЕССИОНАЛОВ sensitivity of the associated antigen in detecting specific antibodies in patients with tuberculosis, as well as in animals with mixed infection, was observed, as evidenced by the study of 105 samples of animal blood serum in the farm, where a double infection was confirmed by the results of allergic, pathological and laboratory studies. Studies have shown the possibility of using of the associated antigen for the simultaneous detection of complement-binding brucellosis and tuberculosis antibodies in blood serum. The data obtained open the prospect of using of an antigenic combination in study of the diagnosis of mixed infections in animals, which is promising of increasing of economic efficiency and reducing the time for identifying epizootic and economic significant diseases.

The aim of this study was to evaluate the effectiveness of four biosorbents in comparison with commercial adsorbents Vetohit and Zaslon in reducing the toxic effects of fumonisin B1. Quantitative determination of fumonisin B1 in supernatants from simulated digestion in different parts of the gastrointestinal tract was carried out by enzyme-linked immunosorbent assay using the RIDASCREEN® FUMONISIN kit (R-Biopharm). In vitro studies (pH 2.0, 8.0) showed that sample № 1, obtained on the basis of extracellular polysaccharides synthesized by strain 574 of the bacterium P. mucilaginosus and calcined bentonite, adsorbed more fumonisin B1 than other biosorbents and commercial preparations (9.43 μg versus 8.60, 8.83, 8.90, 9.09 and 8.13 μg, respectively). This suggests that the developed biosorbents are effective in reducing the toxic effects of fumonisin B1.
