The antibacterial activity of nano-encapsulated basil and cinnamon essential oils against certain multidrug-resistant bacteria recovered from infected wounds
This study was conducted to evaluate the antibacterial activity of nano-encapsulated essential oils of basil (Ocimum basilicum) and cinnamon (Cinnamomum verum) against multidrug-resistant (MDR) bacteria. A total of 115 wound swab samples were collected from patients admitted to Naser Institute, C...

This study was conducted to evaluate the antibacterial activity of nano-encapsulated
essential oils of basil (Ocimum basilicum) and cinnamon (Cinnamomum verum) against
multidrug-resistant (MDR) bacteria. A total of 115 wound swab samples were collected from
patients admitted to Naser Institute, Cairo, Egypt, suffering from wounds discharge; pain,
swelling, foul-smelling, delayed and non-healing wound infections. Six genera of bacteria
were isolated from the collected swab samples, and then identified using conventional
biochemical methods and API 20 kits. Staphylococcus aureus was found to be the most
prevalent isolate (26.1 %), following by Pseudomonas aeruginosa (25.2 %), Klebsiella
pneumonia (23.5 %), Acinetobacter baumannii (12.2 %), Proteus vulgaris (7.8 %), and the
less common isolate of Escherichia coli (5.2 %). Among 14 antibiotics tested in vitro for their
susceptibility using the standard disk diffusion assay, results showed that imipenem was the
most efficient antibiotic against most of the tested Gram (-) and Gram (+) isolates followed by
meropenem. Currently, all the recovered bacterial isolates were MDR. The nano-encapsulated
basil oil (NEBO) and nano-encapsulated cinnamon oil (NECO) showed potential antibacterial
potentials against all the tested MDR bacteria. Results of testing the antibacterial potential of
the NEBO and NECO demonstrated that the encapsulation process protected the oils from
oxidation, and consequently enhanced their antibacterial potencies. It could be concluded that
the nano-encapsulated essential oils act as promising antibacterial agents against the MDR
