Leila Derradji* and Youssef Hadef
The flowery stalks dried by hirtus Thymus are collected in the region of El-Oued (the South of Algeria). The species is spontaneous, used in the traditional medicine in Algeria. To make the evaluation of the bacteriostatic effect of the essential oil, we used the method of the aromatogramme. The selected bacterial strains are collected in a hospital environment (central laboratory of Microbiology C.H.U Annaba): Klebsiella pneumoniae, Proteus vulgaris, Esherichia coli, Pseudomonas aeroginosa and Serratia marcescenc. The results of the aromatogramme show us that the essential oil burned is active on the selected origins which sensitive differs according to the degrees of its dilutions. Indeed important zone of inhibition are observed with diameters affecting 36 mm. The species Thymus hirtus the region of the South of Algeria establishes a source of bioactive natural substances. We have to exploit this source because she could be a solution to the treatment of the infectious pathologies.
Keywords: essential oil, sensibility, bacteriostatic germs, resistance, aromatogram.
