Antimicrobial potential of Sicilian honeys against commensal
Escherichia coli and pathogenic Salmonella serovar infantis
J Prev Med Hyg. 2013 Dec
INTRODUCTION:
The purpose of this study was to investigate the
antibacterial effect of 71 locally produced honeys from different botanical
sources collected from apiarist's open markets in Sicily .
METHODS:
Antimicrobial activity was determined against Escherichia
coli (ATCC 25922) and Salmonella serovar Infantis (ATCC 1523) by an
agar-diffusion assay from the estimation of the diameter of the inhibition zone
produced by the honeys. Statistically) significant differences (P < .000)
regarding inhibition were observed for the honeys tested.
RESULTS:
The chestnut and polyfloral honey samples exhibited the
largest and highest inhibition (diameter of the inhibition zone > 25 mm)
against both E. coli and S. Infantis. The honey of oregano origin showed
intermediate or low activity against E. coli and S. Infantis, respectively.
Prickly pear and erica honeys showed no antimicrobial activity against the two
reference strains.
DISCUSSION:
The results may partially suggest the usefulness of
the Sicilian honeys on treating multi-resistant enterobacteria. In light of the
enormous potential for application of honey in the clinical practice, it is
important that research continues not only into those honeys well recognized as
antimicrobial, but also into other locally produced and yet untested honeys.
