Study of the biocidal properties of a new agent based on modified bee parchment

The problem of prevention and treatment of gastrointestinal diseases of infectious etiology of calves is still relevant. Recently, bee products (honey, bee venom, bee parchment, propolis, royal jelly) have been used for this purpose. Taking into account the unique properties of beekeeping products, we have developed a new biologically active agent based on modified bee parchment. The developed product is made by alkaline hydrolysis of 3-4 % solution of sodium hydroxide of bee parchment and contains a complex of biologically active substances. In order to accelerate the study of the effect of the developed product on living organisms, a model of using the ciliated protistic organism Paramecium caudatum , inhabiting freshwater reservoirs, was proposed. The aim of the study was to study the biocidal properties of the developed agent of the biological model. The study of the effect of a new agent based on modified bee parchment was carried out according to the methodological recommendations “Screening of bio-stimulating and biocidal substances (adaptogens, bactericides and other drugs)” on a model of a free-living infusoria slipper Paramecium caudatum . As a result of the study, it was found that the developed agent has pronounced biocidal properties (similar to widely used antibacterial drugs). In order to study the cytotoxic and ecotoxic effects of the developed medium, it is necessary to conduct a number of additional studies to determine their comprehensive effect on protistic organisms as a test laboratory model.
