Preliminary Studies on the Antibacterial Effect of the Assortment of Polyfloral Honey from the Western Part of Romania.

Honey is a bee product that has antimicrobial activity, between different types of honey there being differences in terms of effectiveness and mechanisms of action against the same type of microorganism. Given the constant increase in the number of antibiotic-resistant bacteria and the need to find natural alternatives to them, the purpose of this study was to evaluate the antibacterial activity of polyfloral honey in western Romania. Honey was tested in the following concentrations: 80%; 60%; 40%; 20%; 10%; 5%. Two Gram+ bacterial strains (Staphylococcus aureus ATCC 29213, Streptococcus pneumoniae ATCC 49619) and three Gram- strains (Enterococccus faecalis ATCC 29213, Escherichia coli ATCC 25922 and Salmonella typhimurium ATCC 14028) were used in the study. The results of this study show that polyfloral honey from the western part of Romania has an antiproliferative effect on the bacterial strains tested, depending on the applied concentration. The highest inhibition rates were recorded on Salmonella typhimurium, Streptococcus pneumoniae and Staphylococcus aureus, and the lowest values were recorded in the bacterial strains Enterococcus faecalis and Escherichia coli.
