We aimed in this study to evaluate the effectiveness of Syrian propolis on some bacterial strains isolated from Al-Assad hospital in Latakia, to estimate its antimicrobial activity. Thus, we studied two propolis samples from two regions in the Syrian
coast, and prepared ethanolic extracts of propolis (EEP) with different concentrations (0.5%, 1%, 5%, 10%, and 20%). Then we tested these extracts on four strains of bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii), using pore method on Muller Hinton Agar. As we observed, the bacteria showed diverse susceptibility to the extracts and the most susceptible bacterium was Staphylococcus aureus which was sensitive to all concentrations and especially for EEP 20%. However, the least affected bacteria were E. coli and Pseudomonas, as the 0.5% and 1% EEP had no efficacy. On the other hand, there were little differences in antimicrobial activity between the two samples of propolis.
This In Vivo study aimed to compare the antibacterial activity of
alcoholic extract of propolis and Miswak with sodium hypochlorite and saline.
The study was performed on 40 infected single root canals for
patients of both sexes, regardless of gender or age.
Essential oils from peels of 6 citrus species were extracted. The species were
lemon (Citrus limon), orange (C. sinensis), grapefruit (C. paradisi), pomelo
(C. maxima), mandarin (C. reticulata) and bitter lemon (C. aurantium) using
hydro-distillat
ion (Clevenger type).
In general Gram-positive bacteria were more sensitive to the oil
extracts tested than Gram-negative bacteria, and P. aeruginosa was the most
sensitive within the Gram-negative group.
