Propolis and wax antimicrobial potential of different species of bees stingless

Abstract

-The objective to evaluate antimicrobial activity of propolis and wax different species of stingless bees front of the pathogenic bacteria. Bees wax were collected Canudo (Scaptotrigona sp.), Jandaíra (Melipona subnitida) and Jati (Plebéia sp.), and two samples of propolis species Cupira (Partamona sp.) and Jati (Plebléia sp). For the analysis of the antimicrobial activity of wax and propolis in hydroalcoholic extracts were produced concentrations of 100, 75 and 50 µg/mL -1 and used diffusion technique discs. To evaluate the antimicrobial activity of the extracts were used strains Enterobacter aerogenes (ATCC 1304), Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 6538). It was observed that the extracts of Canudo bees wax, and Jandaíra Jati showed activity against the tested microorganisms. As for the propolis extracts was verified that the Cupira at concentration of 100 µg/mL -1 had activity against all the tested bacterial strains, as in other concentrations, only Staphylococcus aureus was inhibited their growth. The Jati propolis extract inhibited the bacteria Enterobacter aerogenes and Staphylococcus aureus at a concentration of 100 µg/mL -1 and E. coli suffered no inhibition. So the wax and propolis extracts of bee species assessed sting have antimicrobial potential against strains of microorganisms tested.
