Atividade antifúngica e potencial antibiofiome do extrato hidroetanólico de Spondias mombin L. e de suas frações frente a leveduras do gênero Candida. 2021. 73f.

The treatment of this pathology is carried out with antifungal agents, but due to the resistance of the fungi that cause this disease, it is necessary to know other antifungal agents. The antimicrobial action of the hydroethanolic extract of Spondias mombin L. is already known and it is essential that the antibiofilm activity of the substances be researched, since these fungi cause illness when they accumulate and proliferate. Knowing that, this study aimed to investigate the antifungal and antibiofilm action of the hydroethanolic extract (EH) of Spondias mombin L. and its fractions, against fungi of the genus Candida, of clinical importance. For this, the minimum inhibitory concentration was determined through the use of disks and the technique of microdilution in broth, minimum inhibitory concentration of adhesion, determination of the fungal death curve and antibiofilm activity of the fractions of phenolic acids, flavonoids and tannin, against the fungi Candida albicans, Candida tropicalis, Candida Krusei and Candida Glabrata, using nystatin (100,000 IU) as a positive control, in triplicate. It was seen that the antifungal and antibiofilm activity of EH and its analyzed fractions exists, however, when we compare the fractions with EH, the latter showed better activity at its highest concentrations (500 µg/mL e 250 µg/mL) and when we draw the comparison between the antifungal and antibiofilm action of the tested substances and the control group, we had better results than the control group against the tested fungi. Thus, it was possible to conclude that the hydroethanolic extract presented superior results of antifungal activity against all tested microorganisms, except C. krusei and antibiofilm against at least one of the Candida species and that this extract had very similar results and, for times higher than the control group.Acesso AbertoAnacardiaceaeFitoterapiaCandidíase bucaldoctoralThesis
