Susceptibility of Candida albicans Strains Isolated from Vaginal Secretion in Front of the Mycocins of Wickerhamomyces anomalus.

Mycocins are substances that have the potential to affect other sensitive yeasts or microorganisms. Wickerhamomyces anomalus is a yeast that produces mycocins that have great biotechnological potential, being highly competitive in many habitats, as it is adaptable to a wide range of environmental conditions. Thus, they are targets for studies in different areas, including the environment, industry, and medical sciences. Yeasts of the genus Candida are of great importance due to the high frequency with which they colonize and infect the human host. Yeast infections are often difficult to treat due to the acquisition of resistance against antifungals, leading to studies focusing in new treatment alternatives. This work aims to verify the inhibition of Candida albicans isolated from vaginal secretion by mycocins produced by Wickerhamomyces anomalus. Tests were carried out in solid medium and microdilution tests, where mycocins proved to be efficient in inhibiting the growth of C. albicans, hemolysis, and irritation in an organotypic model, which showed that the mycocins produced by W. anomalus are safe and non-irritating. Thus, the results of this work can provide scientific evidence for the application of mycocins in the production of new antifungal alternatives.
