Antibacterial Activity of Polyphenolic Extracts from Different Algerian Honeys against Methicillin Resistant Staphylococcus aureus

The prevalence of patients infected with Methicillin resistant Staphylococcus aureus present different
problems of nosocomial infections diseases in addition to multidrug resistance. This work aim to
evaluate the antibacterial effect of four polyphenolic extracts from honey against Methicillin resistant
Staphylococcus aureus. An extraction of polyphenol was carried out from different honey samples
collected from different regions of the Algerian territory. First, the physicochemical, microbiological
quality and pollen analysis was studied. Then, the evaluation of the antibacterial effect was performed
by the determination of inhibition diameter and the minimal inhibitory concentration. The results clearly
show the sensitivity of Methicillin Resistant Staphylococcus aureus against the polyphenolic extracts.
The four samples presented an inhibitory effect and the polyphenolic extract of Jijel has the highest
inhibitory effect among all extracts. This activity depend not only with the type of polyphenolic
compounds but also with the botanical origin and the type of honey as honeydew honeys which is
more effective than nectar honey.
