Дослідження сорбційних та дезінфікуючих властивостей осушувача підстилки «Міказез»

Abstract

The article presents the results of experimental studies of the sorption and disinfecting properties of the drying agent for layer dryer "Mikadez" TU U 08. 1 - 36613759 - 002: 2013 in vitro for standard test - cultures of microorganisms (Echerichia coli, Staphilococcus aureus). It is known that the increased moisture content of the litter leads to disruption of biothermal processes and the development of pathogenic, anaerobic and putrefactive microflora in it, contributes to contamination with various pathogenic microorganisms, affects the health and productivity of poultry, the yield and quality of products. The experiments were carried out in the Scientific Laboratory of Molecular Genetic Research Methods. P.I. Verbitsky Department of Epizootology and Veterinary Management of the Kharkov State Zooveterinary Academy using generally accepted microbiological methods. The sensitivity of microorganisms of the standard test - cultures of Echerichia coli, Staphilococcus aureus to the drug "Mikadez" was determined by the disco - diffusion method. According to the research results, it was found that the dryer "Mikadez", which contains mineral and plant adsorbents has sorption properties and negatively affects the development of test cultures of microorganisms. The effect of the drug on microbial cells is due to the effect of active substances (nanodispersed amorphous silicon dioxide and other minerals of the complex) on glucoprotein structures and phospholipids of membranes, surface receptors of microorganisms, which leads to a detrimental effect on the development and viability of microorganisms of standard test cultures Echerichia coli and Staphilococcus aureus, the drug also has a pronounced sorption effect (bacagglutination) on G + and G- microorganisms, in which its antiseptic and disinfecting properties are manifested. The zone of growth inhibition of standard test - cultures by the disc - diffusion method was 17-20 mm. &nbsp
