Avaliação das propriedades antimicrobianas do mel e da geoprópolis da abelha plebeia aff. Flavocincta frente aos microorganismos staphylococcus aureus e enterococcus faecalis.

Abstract

Due to the great demand for natural products from stingless bees that produce honey and the geopropolis, delicacies that exploited for pharmacological purposes, the present work aimed to evaluate the therapeutic potential through the antimicrobial properties of honey alcohol extract and the geopropolis, produced by Plebeian aff. Flavocincta, which were collected in a meliponary in the Quixaba settlement in the municipality of Mossoró - RN, and in the Amazona settlement in the municipality of Serra do Mel – RN, against the microorganisms Staphylococcus aureus and Enterococcus faecalis. The technique of plate diffusion with Mueller-Hinton solid media was used for this purpose, taking as reference the agar diffusion method, according to Kirby-Bauer (1966) and the recommendations of the National Committee for Clinical Laboratory Standart (NCCLS, 2002). The alcoholic extract of bee propolis Plebeian aff. Flavocincta considered effective as regards antibacterial activity in relation to both Staphylococcus aureus and Enterococcus faecalis microorganisms, since during the analysis of the plaques made in triplicate for each bacterium, they had an effect that showed similar reactions, demonstrating that the two questioned microorganisms did not grow on the specific surface of the propolis drip. However, similarly to the bacteria under study, there were no inhibitory halos, which differed from the control antibiotics, which normally exhibited the formation of the inhibitory halo suggestive of the antibiotic used. Thus, not allowing enough conditions to quantitative measure this antimicrobial action. The analysis of the alcoholic extract of bee honey Plebeian aff. Flavocincta, carried out under the same conditions of the analysis of the propolis alcoholic extract, was considered ineffective in the antimicrobial action against the microorganisms studied, considering that, they did not offer characteristics that indicated an inhibitory action, since the two microorganisms invaded the total area of the drip Honey extract. So that they presented bacterial growth under the substance under analysis, which differed from the control antibiotics that normally presented the formation of the inhibitory halo suggestive of the antibiotic used.
