ABSTRACT
Background: Garlic (Allium sativum) has had an important
dietary and medicinal role for centuries. It is a large annual
plant of the Liliaceae family. Garlic is used in traditional medicine
for infectious disease and some other cases.
Aims: The study aims at determining the antibacterial activity of of
aquatic garlic extract, apple vinegar and apple vinegar - garlic extract
combination against some bacterial isolates.
Methods: The antibacterial effects of aqueous garlic extract,
apple vinegar, and apple vinegar- garlic extract combination against
9 Gram-positive and 5 Gram-negative bacterial isolates, including
Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus
pyogenes, Enterococcus feacalis, Streptococcus pneumoniae,
Pseudomonas aeruginosa, Pseudomonas fluresence, Enterobacter
aerugenes, Klebsiella pneumoniae, Escherchia coli, Salmonella
typhi, Proteus mirabilis, Proteus vulgaris, and Acinetobacter, all of
them were studied.
Results: Antibacterial activity of aqueous garlic extract at 50%
concentrations by well-diffusion method was characterized by
inhibition zones of 5 Gram-positive and 9 Gram-negative
pathogenic bacteria. The maximum zone of inhibition of aqueous
garlic extract was observed in Salmonella typhi and the minimum
was observed for Proteus sp. All organisms tested were highly
sensitive to apple vinegar- garlic extract combination, whereas all
organisms tested were slightly sensitive to apple vinegar.
Conclusions: In summary, the aqueous garlic extract showed a
wide spectrum activity and appears to satisfy all of the criteria
for antibacterial agents. These results suggest that garlic can be
used to protect food and reduce the risk of contamination from
pathogenic microorganisms.
Keywords: Garlic, Apple Vinegar, Apple Vinegar - Garlic Extract
