Avaliação antimicrobiana do mel e da geoprópolis da Plebeia aff. flavocincta aos agentes Pseudomonas aeruginosa e Escherichia coli.

Abstract

The stingless bees or meliponines make up the most diverse group of social bees, distributed in tropical and subtropical regions of the world. The use of the various products of meliponicultura is millenarian among the peoples of the Americas. Some studies highlight the anti-inflammatory and antioxidant activity of honey and geopropolis, attributed to the various polyphenolic compounds that make them up. In the last decades, due to the appearance of antibiotic-resistant pathogens and the incidence of side effects caused by drugs, researchers have investigated the antimicrobial properties of different natural products, such as honey and geopropolis. This study aimed to evaluate in vitro the antimicrobial activity of the honeybee Jati (Plebeia aff. Flavocincta) in bioassays for the control of Pseudomonas aeruginosa and Escherichia coli. The method used was the agar diffusion test, also called plate diffusion. The results of this research demonstrated that the geopropolis extract formed inhibition halo against Escherichia coli, as well as against Pseudomonas aeruginosa, having bacteriostatic activity, even after 8 days of observation. Honey extract did not present antibacterial activity in any of the strains of this study, showing no inhibition halo, thus occurring bacterial growth.
