Klimentova E.G. THE EFFECT OF BACILLUS THURINGIENSIS δ-ENDOTOXIN ON THE LEVELOF PELLICLE FORMING ACTIVITY AND ADHESIVE PROPERTIESOF OPPORTUNISTIC PATHOGENIC BACTERIA Found that the B. thuringiensis δ-endotoxin subsp. kurstaki introduced in a long time per os laboratory mice, lead to the development of dysbiosis, which is a change to the ability of microorganisms to film formation and adhesion properties of opportunistic pathogens, which creates conditions for the subsequent invasion of the host tissue and causes infections.Key words: B. thuringiensis δ-endotoxin, the formation of bacterial biofilms, increased adhesiveness of microorganisms.
