- Abstract
OBJECTIVE This study aims to investigate the anti-Staphylococcal activity of honey in combination with bovine milk. MATERIALS & METHODS One sample of Omani honey (OH26) was investigated for its activity against Staphylococcus aureus (NCTC 6571), using an agar well diffusion technique. The honey sample gave excellent anti-Staphylococcal activity. Four different samples of bovine milk (Al Marai, Al Rawabi, A'Sfwa and Sohar) were investigated for their anti-Staphylococcal activity. Two of the milk samples were investigated for their Staphylococcus aureus killing rates, each on its own and in combination with the Omani honey using tube dilution technique. RESULTS Two samples of milk demonstrated moderate anti-Staphylococcal inhibitory activity (zone of inhibition 20mm). OH26 demonstrated excellent anti-Staphylococcal activity (zone of inhibition of 42 mm). OH26 in combination with milk demonstrated enhanced killing activity. At 2 hours, honey demonstrated 50% killing, while the combination of honey with either Al-Marai or Al Rawabi milk demonstrated 66% and 69% killing, respectively. At 6 hours, honey killed 71% while the combination with either milk samples killed >90%. The combination of honey and milk showed better killing rates, enhancing the killing activity by approximately 20%. Honey alone requires more than 20 hours for killing all bacteria, whereas when milk is combined with honey the time for 100% killing is reduced to less than 16 hours. CONCLUSIONS Omani honey possesses in-vitro anti-Staphylococcus aureus activity. Not all milk samples possessed anti-Staphylococcal activity. The killing activity of milk is enhanced by the use of honey.
