• Abstract:

  Denture stomatitis (DS) is considered a common alteration in the palatal mucosa region in users of tooth-tissue supported dentures. Despite the outstanding role of the fungal species Candida albicans in this disease, its etiology is also associated with bacteria of the genus Staphylococcus, Pseudomonas and enterobacteria. The classical treatment for it is allophatic, however there is an increasing interest in the use of natural products, like the case of the fruit of the Plinia cauliflora (Brazilian Grape Tree), a fruitful species native of Brazil, whose antioxidant and antimicrobial properties may characterize it as herbal or phytotherapic. The objective of this paper was to evaluate the inhibitory effect of the jabuticaba skin on the strains of Staphylococcus spp., enterobacteria, Pseudomonas aeruginosa and Candida albicans. Suspensions of these microorganisms have been grown in means of culture added with the skin of the Plinia cauliflora in concentrations from 0,5 to 50 mg/mL (agar dilution method) and incubated at 37°C for 24 hours. In the case of Staphylococcus spp. and Pseudomonas aeruginosa, the results were similar, with minimum inhibitory concentration (MIC) 50 and 90 of 15 and 20 mg/mL, respectively. As for the enterobacteria, the MIC 50 was of 20 mg/mL and MIC 90 of 30mg/mL. The strains of Candida albicans have not been inhibited to the maximum concentration tested (50 mg/mL). From the applied methodology, it was possible to verify that the skin of the Plinia cauliflora was able to inhibit enterobacteria, Staphylococcus spp. and Pseudomonas aeruginosa, but not Candida albicans.
