Abstract

The antimicrobial activity of Bolivian propolis was assessed for the first time on a panel of bacteria and two endemic parasitic protozoa. Ten samples of Bolivian propolis and their main constituents were tested using the micro-broth dilution method against 11 bacterial pathogenic strains as well as against promastigotes of Leishmania amazonensis and L. braziliensis using the XTT-based colorimetric method. The methanolic extracts showed antibacterial effect ranging from inactive (MICs > 1000 μg ml^-1) to low (MICs 250-1000 μg ml^-1), moderate (62·5-125 μg ml^-1) and high antibacterial activity (MIC 31·2 μg ml^-1), according to the collection place and chemical composition. The most active samples towards Leishmania species were from Cochabamba and Tarija, with IC₅₀ values of 12·1 and 7·8, 8·0 and 10·9 μg ml^-1 against L. amazonensis and Leishmania brasiliensis respectively. The results show that the best antibacterial and antiprotozoal effect was observed for some phenolic-rich propolis.
