Assessing the Antibacterial Activity of Honey and Lemon Juice Against Bacterial Isolated from Upper Respiratory Tract Infections
This study aims to assess the antibacterial activity of honey and lemon juice extracts on clinical isolates from
upper respiratory tract infections. The antibacterial effect of honey and lemon were investigated, their use separately and in
combination against Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiellapneumoniae, Streptococcus pyogenes and
Streptococcus pneumoniae.. Agar diffusion methods were employed to assess degree of susceptibility of the bacteria isolates
to honey and lemon juice. Lemon juice together with mixture of honey and lemon juice alone showed a very good
antibacterial activity when compared to honey itself. The results indicated that both (lemon and honey) extracts showed
considerable antibacterial activity against all clinical isolates from respiratory tract infections. This study justifies the use of
honey and lemon juice separately and in mixture as an alternative medicine in the treatment of respiratory tract infections.
