ABSTRACT

In this study, the antimicrobial activity of eight natural extracts (Citrus bergamia, Ocimum basilicum, Melissa officinalis, Eucaliptus, Pelargonium graveolens, Argania spinosa, Ricinus communis) over some nosocomial bacterial strains isolated from hospital units (Staphylococcus aureus M215, Escherichia coli M49 and Streptococcus pyogenes M372) has been studied using the diffusion method. The highest antibacterial effect was exhibited by the basil (Ocimum basilicum) and eucalyptus (Eucaliptus) oil (0.7 mm and 1.3 mm, 2.3 mm and 2.65 mm respectively) while the lowest was credited to the lemon balm (Melissa officinalis). An inhibition effect over the Staphylococcus aureus M215, Escherichia coli M49 and Streptococcus pyogenes M372 was also observed in the case of the argan (Argania spinosa) oil (0,3 mm-1,25 mm). The results of the present study suggest the fact that essential oils can be used to treat infections caused by these bacterial strains.
