The aim of this study was to determine the differences between the chemical composition of three different types of bee honeys obtained from different floral origins and produced in different regions in Sudan. This study also aimed to investigate the effect of the three bee honey samples on the growth of common pathogenic bacteria. The apparent reducing sugars content, glucose content, fructose content, fructose: glucose ratio, sucrose content, moisture content, protein content, ash content, macro-mineral elements (K, Na, Mg and Ca), micro-mineral elements (Cu, Co, Zn, Fe and Mn), pH, free acidity, lactone, total acidity, total polyphenols, proline, diastase number and two physical properties: refractive index and electrical conductivity were determined in the bee honey samples (A, B and C). The inhibitory effect of five different concentrations (10%, 25%, 50%, 75% and full strength) of the bee honeys samples (A, B and C) on the growth of standard pathogenic strains of Staphylococcus aureus ATCC (25923), Pseudomonas aeruginosa ATCC (27853) and Escherichia coli ATCC (25922) was tested. Highly significant differences between the bee honey samples were obtained for moisture content (13.47 – 16.93%), fructose: glucose ratio (1.21 – 1.35), sucrose content (1.41 – 11.03 %), free acidity (62.73 – 81.4 meq/ kg), lactone (5.08 – 9 meq/ kg), total acidity (71.73 – 88.73 meq/ kg), diastase number (4.64 – 13.47) and refractive index (1.4944 – 1.5031). Significant differences were observed for the following: fructose content (42.24 – 44.36%), glucose content (32.64 – 35.08%) and the protein content (0.67 – 0.93 %). Insignificant differences were observed for the apparent reducing sugars content (76.76- 79.45%), ash content (0.38 – 0.57 %), pH value (4.44 – 4.47), total polyphenols (0.11 – 0.13 %), proline content (65.76 – 93.62 mg/ 100g) and the electrical conductivity (0.9 – 1.1 mS/ cm). The mineral elements content was also different. Potassium was the highest among the macro-mineral elements and iron was the highest among the micro-mineral elements. Macro-mineral elements (ppm) ranged, K (1500 – 2500), Na (55- 110), Mg (16.25 – 75), Ca (14.25 – 21.5) and the micro-mineral elements (ppm), Fe (20.33 – 32.93), Cu (1.05 - 1.63), Mn (0.83 – 1.98), Co (0.65 – 1.13), Zn (0.35 – 1.5). The antibacterial activities of the bee honey samples (A, B and C) varied causing different diameters of growth inhibition zones (mm). Samples A, B and C caused the occurrence of growth inhibition zones on plates of S. aureus and E. coli when they are in their full strength only. Sample B caused the growth inhibition of P. aeruginosa till 50 % concentrations and sample C till 75% concentrations. Sample B had the highest potency among the bee honeys samples tested. Generally, bee honeys from different floral origins vary considerably in their chemical properties as well as their antibacterial activities.
