<abstract xmlns="http://www.w3.org/1999/xhtml"><p>The first aim of the study was to compare the antibacterial activity of several types of honey of different origins, against some bacterial resistant strains.

Ten honey samples (polyfloral, linden, acacia, manna, and sunflower) from the centre of Romania were tested to determine their antibacterial properties against the following bacterial species: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enterica serovar Typhimurium, Bacillus cereus, Bacillus subtilis, and Listeria monocytogenes. Bacterial cultures in nutrient broth and the culture medium Mueller-Hinton agar were used. The susceptibility to antibiotics was performed using the disk diffusion method. All honey samples showed antibacterial activity on the isolated bacterial strains, in particular polyfloral (inhibition zone 13-21 mm in diameter) - because it is the source of several plants, and manna (inhibition zone 13-19.5 mm in diameter), and sunflower (inhibition zone 14-18.5 mm in diameter). Pure honey has a significant antibacterial activity against some bacteria which are resistant to antibiotics. Bacterial strains differed in their sensitivity to honeys. Pseudomonas aeruginosa and Staphylococcus aureus were the most sensitive. The present study revealed that honey antibacterial activity depends on the origin of the honey. We also found that there was a significant correlation between antibacterial activity of honeys and the colour of the honey but not between acidity and pH.
