Background
The emergence of multi–drug resistant organisms has created a lot of clinicalproblems. Hence there is a need to find natural alternative treatment to counter the multi–drug resistant organisms. Honey has a well-established usage as wound dressing in ancient and traditional medicine. The aim of this work is to establish a base-line of the antibacterial activity of 32 natural and commercial various honey samples against 8 clinical isolates.
Methods
Thirty two honey samples (raw and commercial honey) collected from different countries with different floral origin were tested in vitro for antibacterial activity against 8 clinical isolates collected from patients, at private Hospital from Sudan, using disk diffusion technique. The following 6 Epsilometer test (E Test), Amoxicillin, Augamentin, Ceftaxime, Chloramphenicol, Gentamicin and tetracycline were used against 8 clinical isolates for Minimum Inhibitory Concentration.
Results
The following 8 clinical isolates were identified by conventional bacteriological methods; Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aerouginosa, Proteus.vulgaris, Salmonella typhi, Shigella sonnei and Methicillin Resistant Staphylococcus aureus (MRSA). Honey has been shown to have antibacterial properties against both Gram-positive and Gram-negative bacteria. The tested organisms showed low sensitivity to antibiotics E test.
Conclusion
Most of the bacterial species studied were uniformly receptive to all the tested honey. In contrast The tested organisms showed low sensitivity to antibiotics with low MIC.
