Antimicrobial activity of ethanol extracts of propolis-antibiotics combination on bacterial and yeast isolates

الملخص EN

Propolis samples were collected during spring and summer seasons (2010 and 2011).

Bacterial and yeast strains ; standard bacterial strain represented by E.

coli ATCC 25922 and S.

typhi TY21, while the local bacterial isolates represented by S.

aureus, P.

aeruginosa, S.

pyogenes, L.

monocytogenes, H.

pylori, E.aerugenes, S.

typhi, K.

pneumoniae, and C.

albicans.

Antimicrobial activities of crude ethanolic extract of Al-Museiab propolis (EEMP) against bacterial and yeast isolates evaluated.

Results revealed that S.

aureus was higher sensitive to 10 % concentration of EEMP than other Gram positive and Gram negative bacteria, while standard E.

coli strain was highly sensitive to EEMP than other Gram negative bacteria.

EEP was not effective against C.

albicans.

The results of Amoxicillin-propolis combination on the bacterial isolates were; synergistic to words P.

aeruginosa, H.

pylori, E.

coli and K.

pneumoniae, while the results of clindamycin-propolis combination on the bacterial isolates were ; synergistic to words P.

aeruginosa, H.

pylori, K.

pneumonia, and E.

aerugenes.

The results of Rifampin-propolis combination on the bacterial isolates were; synergistic to words on P.

aeruginosa, E.

coli, K.

pneumoniae, S.

pyogenes, and E.

aerugenes.

Last but not least, the effect of Nistatin and propolis combination against C.

albicans isolates indicated for additive effect.
