In the modern world, one of the most serious problems in the treatment of chronic infectious diseases of animals is the creation of biomembranes by microorganisms, in which they become inaccessible to the vast majority of antimicrobial agents. In this study, we investigated the structural and functional features of three strains of Candida albicans, Candida tropicalis and Candida africana on the ability to form biomembranes. A reliable diagnostic algorithm for quantitative evaluation of Candida biomembranes and remaining native cells has been tested. The dependence of the biomembrane formation process and the number of remaining native cells on the time of cultivation was determined. Morphological studies of the process of biomembrane formation without architectonics disturbance with the use of scanning electron microscope and cell holographic microscope were carried out. © 2018, Advanced Scientific Research.
