Résumé:
Currently, there is a global public health problem. These include the long-standing
appearance of resistant bacterial strains involved in some post-operative infections.
This work is intended as a contribution to test the effect of antibiotics used in hospitals and to
enhance the essential oil of Thymus vulgaris from the Nedroma Wilaya region of Tlemcen
(Algeria) on the germs responsible for post-operative infections.
Samples collected from Pus and Compress on wounds show a high prevalence of Grampositive
bacteria such as Staphylococcus aureus from pus specimens and Enterobacteriaceae
such as Escherichia coli, Klebsiella pneumoniae ssp pneumoniae.
The antibiotic tests carried out showed a very high resistance rate of about 8 out of 16
antibiotics tested in strains such as Pseudomonas aeruginosa, Escherichia Coli, Klebsiella
pneumoniae ssp pneumoniae, Staphylococcus aureus with zero diameters for several strains Of
S. aureus.
The antibacterial activity demonstrated by the antibio-aromatogram method, showed
that the essential oil of Thymus vulgaris from the Nedroma Wilaya region of Tlemcen (Algeria)
showed a significant inhibitory effect on certain bacterial strains with profiles of weak
resistance (Proteus mirabilis, E. coli ATCC25922). Medium (Citrobacter freundii, Shigella
group) and Fort (Staphylococcus aureus and Klebsiella pneumoniae ssp pneumoniae) with
diameters of significant inhibition zones.
This study allowed us to evaluate the antibacterial power of the essential oil of Thymus
vulgaris in the Nedroma Wilaya region of Tlemcen (Algeria). Therefore, in our study, we
observed a decrease in the inhibition diameter proportional to the resistance gradient of the
bacteria.
