Antimicrobial Effect of Essential Oils of the Plant Eucalyptus Camaldulensis on Some Pathogenic Bacteria

Mouna Mehani and Segni Ladjel

Abstract—Essential oils have many therapeutic properties. In herbal medicine, they are used for their antiseptic properties against infectious diseases of fungal origin, against dermatophytes, those of bacterial origin [3, 4]. The aim of our study is to determine the antimicrobial effect of essential oils of the plant Eucalyptus camaldulensis on some pathogenic bacteria which is a medicinal plant used in traditional therapy. The test adopted is based on the diffusion method on solid medium (sensitivity), this method allows to determine the susceptibility or resistance of an organism vis-à-vis the sample studied. The analysis allowed obtaining by hydrodistillation of the plant samples one essential oil of light Yellow color with a 0, 99 % returns. Our study reveals that essential oil of the plant Eucalyptus camaldulensis has a different effect on the resistance of germs to Pseudomonas aeruginosa is a strain weakly sensitive with 6,33 mm zone of inhibition, Escherichia coli is moderately sensitive with a zone of inhibition equal to 9,69 mm. By against, Antirobactère and Proteus are strains which represent a high sensitivity zone of inhibition equal to 10 and 11,66 mm respectively.

Index Terms—Essential oils, hydrodistillation, eucalyptus camnedulensis, antibiogramme.
