Attention should be focused on natural alternatives to antibiotics, like propolis, royal jelly (R J) and honeys. They all have strong antibacterial properties due to the active substances they contain. This study investigated the effect of combination of water soluble propolis (WSP) Greitl20 or fresh royal jelly (F-RJ) (MiZigoj) and Forest honeys as antibacterial against Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, Acinetobacter baumanii, Staphylococcus aureus, methicillin resistant Staphylococcus aureus (MRSA), Streptococcus pyogenes, Streptococcus agalactiae and Candida albicans. These substances are also cell growth promoters for human macrophage (TLT) cell line. WSP Greitl20, F-RJ (M) and different Forest honeys were prepared in saline as 10% solutions. The antimicrobial activity was expressed as the minimal inhibitory concentration (MIC) in mg/mL. The growth promotion activity was measured at optical density (OD) 595 nm. The combination ofWSP Greitl20 with different Forest honeys is better than F-RJ (M) in same combination with different Forest honeys. The best antibacterial/antifungal activity was found with the combination of 10% WSP Greit 120 in the Forest honey (1:10) from Italy or Spain. When measuring the growth promoting activity of TLT cell line, the best activity was detected at the combination of 10% WSP Greitl20 in the Forest honey from Italy (GI3 = 0.796 ± 0.014 and GI5 = 1.133± 0.022). Antimicrobial and growth promoting activities are correlated and WSP-dependent.展开更多
