Antibacterial Activity of Various Syrian Honey Types against Pseudomonas aueruginosa

Pseudomonas aeruginosa is an opportunistic pathogen causing severe, acute and chronic nosocomial infections in urinary and pulmonary tracts, burns and wounds. Currently, there is an urgent and global need for alternative antimicrobial strategies to fight the continuous rise of P. aeruginosa resistance to different antibiotics. This led to a re-evaluation of the therapeutic use of ancient medicines such as honey. Different concentrations ranging from 0.02-50% of six different Syrian honeys were used in this study against resistant P. aeruginosa. The minimum inhibitory concentration was determined using spectrophotometric at 620 nm. Carduoideae flowers, black seed, anise and oak honey samples showed a MIC of 12.5%, whereas the MIC of Montana and cotton honey samples was 25%. In conclusion, Syrian honey possesses an in vitro antibacterial activity against P. aeruginosa and could be an alternative topical choice in the treatment of wound infections.
