Antibacterial efficiency for alcoholic extracted of (thymus vulgaris and negilla sativa)‎

الملخص EN

The aim of this study was to evaluate the Antibacterial activity of various concentrations of mixtures of Thymus vulgaris and Negilla sativa on various pathogenic bacteria (Escherichia coli, Pseudomonas aeroginosa, Staphylococcus aureus, Enterococcus faecalis, Serratia sp.

and Bacillus subtilis ) In general, all extracts in concentraction (40 μg/ml) have the same effects on Gram positive bacteria (, Staphylococcus aureus, Streptococcus faecalis, and Bacillus subtilis) , whereas the less effect on Escherichia coli (60 μg /ml), the biggest effect on Serratia sp.

(20 μg /ml) and Pseudomonas aeroginosa was (40 μg /ml) The limits of minimal inhibitory concentration (MIC) of all extracts are between (10-320 μg /ml).

The efficiency of antibacterial activity of T.

vulgaris and N.

sativa extract were compared with efficiency of standard antibiotics against (Ampicillin, Amikacin, Erythromycin, Kanamicin, Tobramycin, Imipenem, Neomycin, cephalothin, Cephalexin and Augmentin) the same bacterial types.
