The aim of this study was to determine the suitability of clove and rosemary oil to incorporate them in the probiotic yeast preparations for animals, as additives which enhance the activity of antimicrobial preparations. The effect of plant oils on the growth of potentially probiotic yeast Candida guilliermondii 1621 KKP was assessed, the antibacterial activity of this yeast was acknowledged previously. Experiments were performed using the impedimetric method and traditional microbiological techniques. It was found that the presence of rosemary essential oil reduces the growth of Candida guilliermondi KKP 1621 to 40 percent at a concentration of 0,02 of the oil in the medium and 30 percent at a oil concetration of 0,001 percent. The clove oil less limits the growth of Candida guilliermondii KKP 1621. It was also demonstrated that the presence of essential oils at concentrations of 0,02 percent does not inhibit the growth of selected pathogenic strains of Salmonella and Escherichia, regardless of the presence in the medium of yeast Candida guilliermondii KKP 1621
