Synergistic effect of propolis and antibiotics on the Salmonella Typhi TY21

الملخص EN

The study was aimed at determining the synergistic effect of crude ethanolic extract of AL-Najaf propolis (EENP) with antibiotic (Ampicilin and Gentamycin) against Salmonella typhi by the method of disc diffusion.

Result revealed that EEP a good antibacterial activity against bacteria at different concentrations 100, 50 mg / ml and the results of Apmicillin–propolis combination on the bacterial isolates were ; synergistic to words Salmonella Typhi.

Statistical analysis showed significant differences between effect of Apmicillin and Apmicillin–propolis combination on bacterial isolates, there was no significant differences between gentamycin and gentamycin–propolis combination at level (P ≤ 0.05).

But there is additive effect on salmonella typhi.
