Abstract

The clinical significance of Pseudomonas aeruginosa and Escherichia coli is a strong factor for regular monitoring of their sensitivity to both established and novel antimicrobial compounds. Human isolates of these organisms were collected from different pathological sources and tested for their sensitivity to gentamicin - an established aminoglycoside antibiotic - and to honey, a natural product that is generating renewed interest for its therapeutic application. In an agar-cup diffusion method, three undiluted different samples of honey and their 1:2 to 1:6 aq. dilutions showed activity on 100% and 96.4% respectively of Pseudomonas aeruginosa isolates compared with 95.4% of Escherichia coli using either of the undiluted or 1:2 aq. dilutions of the honey samples. Gentamicin used in concentrations of 8.0 and 4.0 µg/ml varied in its activity against both organisms but was generally lower than the antibacterial activity of each undiluted honey and its 1:2 aq. dilution. In the event of therapeutic failure with gentamicin or any other related antibiotics, honey offers a suitable and better alternative in managing infected burn wounds and other forms of infected wounds as well as prophylaxis in trauma wounds.
