Abstract: The present study aimed at investigating the susceptibility of the microorganisms Pseudomonas aeruginosa, Salmonella typhi, Escherichia coli, Staphylococcus aureus, and Bacillus subtilis to ethanolic extracts of propolis (EEP) from three regions of Kenya (Taita, Tana and Samburu). Propolis was extracted using four different concentrations of ethanol: pure, 70%, 50%, and 30%. Ethanol (70%) and Streptomycin were used as controls. The agar diffusion method using filter paper disks was employed. Antibacterial acti… Show more

“…However, ethanolic extract and essential oil of propolis present different chemical compositions (20). Probably, diverse extraction procedures result in dissimilar chemical compounds, and ultimately, could contribute to differences in the antibacterial activities (29,30). It is not so clear whether the antibacterial effect may be caused by a single active component or by the synergy of many active constituents found in the essential oil.…”

“…The gram-positive bacteria were more susceptible to propolis-ethanolic-extract, at low concentration than the gramnegative. [25][26][27][28][29][30] mentioned that both the Gram-positive and Gram-negative bacteria were sensitive to propolis but the most sensitive one was the Gram-negative, so until now the effective propolis-ethanolic-extract against different bacteria is unsettled. Flavonoids have been considered to be the main biologically active components in propolis [31,32].…”

“…Treatment with norfloxacin was effective and increased the survival of fish challenged with A. hydrophila. Antibiotics of the family quinolones (norfloxacin and enrofloxacin) and gentamicin proved to be the most efficacious on A. hydrophila isolates [26]. The experimentally infected fish with A. hydrophila in the current study was responded to propolis and norfloxacin treatment.…”
